Authors: Chodor Jaroslaw , Kukielka Leon
Published: January 2014

Properties of the surface layer after cutting or sliding burnishing depend mainly on type of process and its performance conditions. For its comprehensive analysis is necessary to develop an adequate mathematical model and numerical methods of solving it. A common feature of both processes is moving the tool edge on elastic/visco-plastic workpiece. However, these processes are different i.e. the chip formation or chipless forming, therefore, different properties of surface layer depend mainly on: the geometry of the tool edge and its workpiece relative and depth of process. Therefore, this article is about the application of an incremental modelling and numerical solution of the contact problem between movable rigid and elastic/visco-plastic bodies developed in [ to the numerical simulation of physical process of moving a rigid tool on the workpiece.

Authors: Aşık M. Zülfü , Dural Ebru
Published: January 2014

Laminated glass which consists of two glass sheets connected to each other with PVB interlayer is used in many engineering applications for years. Despite the long history of the use of laminated glass in buildings there are serious problems about delamination of laminated glass units. This paper provides information about delamination issues of laminated glass plate structures. Delamination of laminated glass unit may be due to the thinning of PVB (Polyvinyl Butyral) interlayer or the folds which occur during the manufacturing process. Laminated glass behaves in a complex manner due to the effect of geometry that undergoes large deflection even under their own weight and the order difference between the elastic modulus of glass and interlayer. Because of the mentioned reasons large deflection analysis has to be performed in the determination of the effect of delamination on the strength of laminated glasses.

Authors: Liang Dong , Shen Hui Cai , Li Zi Shuo
Published: January 2014

The transverse distribution of lane loading is one of the most concern for the assembly prefabricated T-girder bridges. Longitudinal influence line and transverse distribution coefficient are used in the traditional calculation method of lane loading effects. But, many research results show this method brings a little big error because of the simplification. Along with the advance of computer technology in mathematics, it is not difficult to use the 3D FEM model to calculate the inner force that caused by vehicle load in girder bridge. In this paper, some comparatively accurate 3D FEM models are established to analyze the lane loading effects on the simply supported T-girder bridge. The results show that the moment and shear force of each girder are quite different between traditional method and 3D FEM model. The results indicate that the traditional method in current code is non-conservative.

Published: January 2014

Speed of rolling bearing and flow rate of air have important influences on the bearing’s working temperature under the oil-air lubrication mode. Based on basic principle of lubrication, one of the heat productivity equations of deep groove ball bearing is selected to calculate the heat value of bearing’s cavity. The bearing’s temperature field is simulated by Fluent at different rotational speeds and air flow rates. Results of the simulation show that the highest temperatures of bearing have a quantitative relationship with the bearing’s rotational speeds. The relationships between the velocity of inlet and heat transfer coefficient, viscosity of the lubricant and the heating of bearing are analyzed in the end of this paper.

This paper presents a novel parallel tri-axis force sensor with decoupled feature, and performs its performance analysis. Firstly, the structural characteristics of the parallel tri-axis force sensor are introduced and the stress distribution of each limb elastomer is analyzed. To measure the transformation relationship between the force and strain, the electric bridge is formed by pasting strain on the elastic-sensitive element. Then, the finite element simulation of the elastomer is conducted and performance analysis of the sensor is carried out, which shows that the parallel tri-axis force sensor is decoupled, linear and fully-isotropy. The sensor possesses good static performance and can meet the requirements of tri-axis force measurement in general industrial production. The contents of this paper riches the structure type of the multi-component force sensor and will be useful for the research and development of the parallel force sensor.

Authors: Le Mei Long , Tan Cai Mao , Yu Hang
Published: January 2014

Airline-specific and priority strategy is often used in gate assignment practice. However, there is no such kind of published research paper until now. Taking these practical two as premises, this paper presents a new comprehensive assignment model which considered the factors of multi-runway, service strategy, gate utilization balance and airline-specific gates simultaneously. The data used in the paper is from a hub airport in China, and IBM ILOG CPLEX optimization solver is used to solve the model. Computational result shows that the double runaway can reduce the total waiting time 1155 minutes compared with the single runway; and adopting priority strategy can reduce the waiting time about 30% compared with no priority strategy. As for utilization rate, imposing a utilization rate constraint in the model can greatly reduce the unbalance of gate use.

Aluminium metallization has a disadvantage when it comes to high-end applications as it cannot withstand the high temperature and pressure. This paper studies the factors that affect the surface roughness on a Platinum deposited wafer after reactive ion etching (RIE) using a combination of CF4and Argon gaseous. A total of three controllable process variables, with 8 sets of experiments were scrutinized using a systematically designed design of experiment (DOE). The three variables in the investigation are ICP power, Bias power, and working pressure. The estimate of the effect calculated for ICP power, Bias power, and working pressure are-6.3608, -3.2858, and-5.394 respectively. All three factors gave negative effects. This implies that the surface roughness decreases when ICP power, Bias power, and working pressure is high. The ICP Power is the most influential factor followed by working pressure, and bias power.
