Published: April 2014

Total hip arthroplasty (THA) is a routine procedure for the treatment of advanced hip joint damage. The long-term result of the prosthesis is mainly determined by migration or aseptic loosening caused by bone remodelling. Especially the migration of the artificial hip cup as a consequence of the remodelling process is a major problem. Patient-specific hip cups can be used to counteract this. However, individual hip cups are currently only implanted for the treatment of great deformations or tumours in the hip joint due to the cost-intensive manufacturing. The aim of this project is the development and establishment of a concept for the economical production of patient-individual prosthetic hip cups out of titanium sheets. This process consists of two steps. First, undersized cups of a universal acetabulum geometry are produced. In the second step a true-to-size enlargement of the produced universal cup prothesis is carried out by means of a modified adaptive rubber-die forming process. The development of this process is accompanied by a simulationbased planning of the production process as well as by a realization of a metal forming adapted design method. For the examination of the feasibility of the concept, CT-data of canine pelvis geoemtries are used because of the large number of CT data, which were aviable for the project. Furthermore it is planned, that the first manufactured prototypes will be tested using canine cadaver. In this study the planning of the manufacturing of the standardized titanium sheet metal components is carried out. For this two methods of producing the standardized hip cup were compared. The first method is a hydraulic forming; the second is a normal pressing process with a bunch die and a binder. Pure titanium was introduced in the simulation, which shows the same mechnical properties like the in prosthetics normally used titanium alloy TiAl6V5. The results of the process simulation of both methods showed that the reducing of the blank thickness is a problem of the manufacturing of the prosthesis. Because of that an adaption of the tool geometry was executed and the influence of the increase of the forming temperature at 200 C was examined. These simulations indicated, that the hydraulic forming seems to be a convenient method to produce the prosthetic acetabulum. The first part of the metal forming adapted design method is the deduction of a universal acetabulum geometry, which has to be designed for the production of the standardized component. This deduction shall be realized by means of a superposition of 3D models of pelvis geometries. For this, two different superposition methods were compared and the Best Fit method was determined as the suitable method. By means of the Best fit method a first universal geometry was created.

Published: April 2014

The industrial relevance of bore holes with small diameters and high length-to-diameter ratios rises with the growing requirements on parts and the tendency of components toward downsizing. Examples are components for medical and biomedical products or fuel injection in the automotive industry. An adapted process design is necessary for the production of deep holes with very small diameters, especially when the conditions at the beginning of the deep hole drilling process are unfavorable. In these applications, a hybrid process consisting of a laser pre-drilling and a single-lip deep hole drilling can shorten the process chain in machining components with non-planar surfaces, or can reduce tool wear in machining case-hardened materials. In this research, the combination of laser and single-lip drilling processes was realized and investigated for the very first time. In addition, results for the machining of workpieces with non-planar surfaces are presented.

Authors: Daamen Markus , Dávalos Julca Daniel , Hirt Gerhard
Published: April 2014

Conventional strips can be converted into tailored strips by further processing such as rolling and welding. Tailored strips have a thickness or thickness distribution which is designed according to the expected loads. A new approach for the production of tailored strips is the twin roll casting of profiled strips. This technology combines the advantages of direct strip casting and the production of steel strip with an optimized cross section. In this paper the achievable process limits regarding the geometry of tailored strips with varying thickness in the cross section made by strip profile rolling, twin roll casting and welding are discussed and compared.
Furthermore, experiments to demonstrate the suitability of twin roll casting to produce tailored strips made of AISI 304 stainless steel are treated. A selected tailored strip geometry of 150 x 1.5 mm2 (width x thickness) with a difference in strip thickness of 33% over the width was cast.
Potentials of Pulse Magnetic Forming and Joining
Authors: Uhlmann Eckart , Prasol Lukas , Ziefle Alexander
Published: April 2014

Magnetic pulse production methods such as forming, joining or separating demonstrate innovative high-speed processes. Such processes can be realized using a capacitor and an appropriate tool coil for forming and welding processes. The process strain rates, which can amount to 20,000 s-1, increase the formability of metallic materials significantly.
Magnesium and aluminium alloys find a wider application in the automotive industry due to their light weight potential. Through the low density of these materials, the vehicle weight can be reduced considerably. Due to the hexagonal lattice of magnesium alloys industry-relevant deformation in metal forming processes can only be achieved in hot forming processes. The high-speed forming allows a significant increase of deformability of this alloy.
The use of dissimilar metals in an assembly requires the development of innovative joining methods. Apart from being used form and force closure the magnetic pulse welding and adhesive bonding material with different partners is possible.
Currently at the Institute for Machine Tools and Factory Management (IWF), TU Berlin, various research topics in the field of pulsed magnetic are investigated. The magnetic pulse sheet metal forming of magnesium alloys at room temperature is investigated in a basic research project. A defined demarcation of high-speed forming with respect to the quasi-static deformation is done by means of hardness measurements in the deformation zone. For this purpose a suitable experimental setup with different matrices is constructed. The experimental results of the pulse magnetic deformation are iteratively compared with simulation results. The aim is to develop a new material model which gives a precise prediction about the high-speed process.
In the field of magnetic pulse welding, both basic research and industry-related research projects conducted at the IWF. The process requires an adapted tool coil geometry that meets the requirements of the weld geometry. Different coil geometries and weld geometries and possible applications are presented by way of example, the welding quality is quantified by means of different analytical methods. The material microstructure in the weld zone, characterized by light and scanning electron microscopy shows the typical features of a shock welded joint, as also observed in explosive welding.

Authors: Herrmann Christoph , Raatz Annika , Andrew Stefan , Schmitt Jan
Published: April 2014

The rising number of lithium ion batteries from electric vehicles makes an economically advantageous and technically mature disassembly system for the end-of-life batteries inevitable. The disassembly system needs to cope with the size, the design and the remaining state of charge of the respective battery system. The complex design resulting from the number and type of connection elements challenges an automated disassembly. The realisation of an automated disassembly presupposes the consideration of elements from Design for Disassembly throughout the battery system development.
In this paper a scenario-based development of disassembly systems is presented with varying possible design aspects as well as different amounts of end of life battery systems. These scenarios point out the resulting implications on battery disassembly systems in short, medium and long term. Using a morphological box the best option for each disassembly scenario is identified and framed in a disassembly system design. The disassembly systems are explained and the core elements are introduced. Newly developed and innovative disassembly tools, such as a robot that allows a hybrid human-robot-working-space and an advanced battery cell gripper are introduced. The gripper system for the battery cells enables with an integrated sensor an instant monitoring of the battery cell condition. The proposed disassembly element is verified in an experimental test series with automotive pouch cell batteries.
Simulation and Prediction of Process-Related Power Consumption of Machine Tools
Authors: Heisel Uwe , Braun Steffen
Published: April 2014

Today a criterion for the quality of modern machine tools is their efficient use of energy and resources. Competitiveness can only be maintained if the necessity to significantly reduce the energy consumption of machine tools, plants and facilities is put into practice. Another important aspect is the need to preserve our environment. In order to be able to energetically optimize machine tools, it is essential to know how much energy they consume at all. Hence, this paper deals with modelling the energy consumption to be expected from machining operations. Using these estimations and predictions provides a starting point for carrying out energetic optimizations. The method developed here is presented by example of turning operations. The model comprises the machine components directly associated with the cutting process as well as mediate components such as auxiliary units and peripherals. Experimental tests serve to verify the accuracy of the model. Then the energy consumed by individual components is provisionally categorized as well as their proportion of the total amount of energy consumption. Following this, it is possible to analyze the potentials for saving energy. In future it is intended to minimize and condense the complexity of the model so that it will be possible to simultaneously conduct the simulation on the NC control during the cutting operation. In this way it might become possible to influence the energy state of machine tools in realtime during machining, using expert knowledge about the adaptive control of components and drives, the adjustment of control parameters on the fly or the change of parameters such as cutting speed, feed rate and depth of cut. The investigations presented here were funded by the German Research Foundation within the Research Unit 1088 ECOMATION.
Wear Protection of Deep Drawing Tools by Systematic Optimization of Highly Stressed Surfaces
Authors: Klocke Fritz , Heinen Daniel , Schongen Fabian , Arntz Kristian , Liu Yuan , Bäcker Vladimir , Feldhaus Björn
Published: April 2014

The automotive sector is one of the largest energy consumers in Germany. Requests from politics and industry to significantly reduce emissions require new developments during utilization as well as during production phase. In line with the framework concept "InnoCaT", where more than 60 companies and research facilities from Germany take part, possibilities for producing companies are developed and analyzed to reduce the resource and energy consumption and by this reducing costs along the entire process chain of car body manufacturing.
One approach to design car bodies lighter and more efficiently is to use aluminium and high strength steels. By this means weight and sheet thickness are reduced. However higher strengths of the steels and the adhesion affinity of aluminium significantly increase the requirements regarding the used tool steel. Thus grooves or galling appear more frequent at highly stressed surfaces. To assure high lifetimes and by this increase especially the resource efficiency concerning use of material and setting-up times within the press plant, a local optimization at the highly stressed surfaces is necessary. For this a FEM/BEM-tool for a time efficient and exact calculation of the occurring tool loads for complex die profiles is developed. Based on this development of load calculation a shape-optimization is performed at the corresponding areas. After the geometric optimization of the tool a local laser surface treatment for further wear protection is carried out using laser cladding or laser alloying/ -dispersing. By combining the technologies a highly wear resistant surface is achievable, which increases the tool's lifetime as well as the reproducibility within production.

Authors: Pecat Oliver , Rentsch Rüdiger , Garbrecht Martin , Brinksmeier Ekkard
Published: April 2014

The machining process of carbon fiber reinforced plastics is very complex due to its inhomogeneous material structure and anisotropic properties. Experimental investigation can be very demanding and time consuming because of the different fiber/matrix compositions and the influence of the fiber volume content which needs to be considered. In this work milling of unidirectional CFRP was simulated using two different material models with implicit and explicit description of fiber and matrix. The objective is to improve the knowledge of the physical mechanism of the cutting process and to predict the cutting forces and surface damage. For this purpose machining of unidirectional CFRP with fiber orientations 90°, 0°, +45° and-45° was simulated, verified by experiments. A significant influence of the fiber orientation on all determined variables was found. The cutting mechanism is dominated by matrix crushing for the fiber orientations 90°, 0° and +45°. Surface damage is caused by either matrix cracking and/or failure of fiber/matrix interface and is occurring in orientations 90° and-45° only. Additionally the evolution of a saw-tooth shaped surface could be identified for the-45° orientation.

Authors: Pang Yan Rong , Li Ya Juan , Liu Ran , Qi Shuai , Liu Ru Yue , Zhou Wei
Published: April 2014

In order to achieve the effect of porosity on the mechanical property and acoustic emission (AE) signals of composite materials with mode I delamination, unidirectional tensile tests and real-time AE monitoring of high property and low property composites were conducted. The results show that the porosity of composite materials made a detrimental effect on the mechanical properties. As the load increases to an inflection point, the slope of the curve becomes smaller. And the slope of the high porosity specimen is lower than that of the other one. With the increase of the porosity of composite material, the failure load and tensile strength decrease. AE monitoring data show that different porosity materials lead to different evolution process of the delamination. And the corresponding AE amplitude distribution, relative energy signals are also different. Different from high porosity composites, low porosity composites generated unstable expansion at the inflection point of the load curve in the stretching process. And the highest amplitude and relative energy were obtained at the inflection point.

Authors: Ji Yun
Published: April 2014

Response surface method (RSM) is widely accepted as an efficient method for reliability analysis, especially when the limit state function (LSF) is supposed to be highly nonlinear or closed-form mechanical models to describe the complex structural systems are not available. However, the selection of different response surface functions may result in different computational accuracy and computing time. In this paper, stochastic response surface method (SRSM), in which Hermite polynomials are employed to approximate the real LSF, is adopted in this paper to analyze the fuzzy reliability of structural systems. With a beam presented as an example, traditional methods, such as FORM, JC method and sequence response surface method, and the method raised in the context are compared in case of the study on solving the reliability. The results show that fuzzy reliability analysis with SRSM is relatively much more efficient and less time-consuming, thus the method raised is more suitable for the analysis of this kind of problems.

Two Methods to Test Transducer Array Directivity
Authors: Liu Hong , Zhao Guo Zhu
Published: April 2014

An array which possess more array element number and whose frequency of the drive signal can be as large as possible in a range, directivity will be more preferable. On the other hand, when the structure of the sound radiating surface of the transducer or array layout is symmetrical, the corresponding directivity pattern will be symmetrical. In order to test transducer directivity, two methods are designed. The one is to measure the ultrasonic sound pressure level by instruments. The sound pressure level is measured at multiple points to deduce the directivity angle of the acoustic transducer array. The beam width of the 3×3 array is about at 23kHz, and the directivity acute angle is about 10°; higher frequencies will lead to the side lobes, but it can be negligible when compared to the main lobe. The other method is using the frequency analyzer to test transducer directivity in a silencer chamber. The sound pressure level can be read out from frequency response diagrams. The angle between the sound pressure value that decreasing 3db from the max value 111.7db and the max value is about 11°. So the directivity acute angle is about 11°. It should be noticed that, as the directivity diagram can not be directly attributed, there is some deviation in the conclusion.

Authors: Cucchiella Federica , Gastaldi Massimo
Published: April 2014

In Italy in the past three years, electricity generation from renewables recorded high growth rates. In 2011, it continued to have an upword trend (+7.8% on 2010), reaching 82,961 GWh. The EU directive on renewable requires to increase renewable energy with a target of 19.6% of total electricity consumption from renewables. In 2011, Italy recorded 23.5%, surpassing by wide margin the proposed target. Moreover the year 2011 represents a turning point since until 2010, the extent of renewable generation was mostly affected by the behavior of the hydro source, while in 2011 the hydro output is stable and the new renewables (solar, wind and biomass) increase. At the same time the effort of management science to assessing efficiency is reaching its goals with the use of Data Envelopment Analysis, a mathematical programming technique able to estimate the comparative efficiency of a set of units which, though distinct production processes and technology, take a given level of inputs to produce a given quantity of outputs. In this paper the efficiency of renewable energy technology (photovoltaic, wind, biomass, hydro) is evaluated with Data Envelopment Analysis at regional level in Italy considering investment and operating costs as inputs and installed power capacity, energy intensity and the CO2avoided as outputs. For each sources the more and the less efficient region is selected and an accurate analysis of the obtained results is outlined. The policy implications of the obtained results conclude the paper.

Study on the Fluctuation Law of the Total Coal Output in China
Authors: Zhao Ai Guo , Li Zhong Xue
Published: April 2014

Coal is a major source of energy and an important industrial raw material. Studies show that it is of instructive significance to study the law of cycle fluctuation of coal production for formulating a reasonable coal resource developing plan and guaranteeing the coal supply. Adopting the theory and study framework of the economic cycle fluctuation, this thesis takes the total coal output in China as the object of the study and estimates the fluctuation of coal production by using the econometric methods such as CF filter and the like. Studies show that there is a major cycle fluctuation of 6 years and a seasonal fluctuation of 3 to 6 months of the coal production in China. The additional analysis shows that there is a long term co-integration relationship of the cycle fluctuation of macro economy and seasonal fluctuation of thermal power generation to the cycle fluctuation of coal production in China, which are the major causes of the cycle fluctuation of the coal production; among them, the cycle fluctuation of macro economy has an unidirectional influence on that of the coal production, while the seasonal fluctuation of thermal power generation and the cycle fluctuation of coal production have bidirectional influence.
