This paper focuses on the double hypervelocity impacts of the satellite propellant tank with baffle protection. The simplified 2D axisymmetric analysis model has been built and the double impact damaging effects were simulated based on the SPH algorithm. Three different speeds of the centimeter-size pill (10km/s, 7km/s and 5km/s) were selected and the simulation results turned out to be consistent with the empirical formula of the ground experiments, which proved the effectiveness of the simulation results. The average velocity changing curve showed that the residual energy of the fragment cloud decreased significantly after the second impact.

Published: December 2014

In this study, qualitative and quantitative analyses of peanut oils adulterated with waste oil, soybean oil, corn oil and canola oil were performed by combining near infrared (NIR) spectroscopy with chemometrics methods. With NIR spectrometer, the spectra of 108 adulterated peanut oil samples were collected. The collected data were preprocessed with three different preprocessing approaches, including standard normal variate (SNV) transformation, de-trending (DT), and orthogonal signal correction (OSC). Backward interval partial least squares (BiPLS) was used to extract the characteristic wavelengths of the preprocessed data. On the intervals of the full spectrum and the characteristic wavelengths, support vector classification qualitative discriminant models and support vector regression quantitative analysis models were established. Experiments demonstrated that the established qualitative models could accurately determine the type of adulterant in peanut oil, with the accuracies on both the calibration set and the prediction set reaching 100%. With the quantitative models, the percentage of adulteration (3% ~ 55%) could be determined accurately, with correlation coefficients as high as 99.10%. All the models returned prediction root mean square errors lower than 6.96E-4. It was validated that the combination of NIR spectroscopy with chemometrics methods can realize the qualitative and quantitative detection of adulteration of peanut oil.

One of the most important characteristics of a cosmetic product is maintain or improving the condition and characteristics of the skin surface. In dermatological, respectively cosmetic practice, there is very often a problem of an objective assessment of the obtained data, which corresponds to visual changes in skin relief. With technical advancements has it been proposed many approaches of solution: mechanical needle devices, optical interference devices, and microscopic, holographic, laser and photometers ones. Each of them has its advantages and negative qualities. The newest devices allow not only two-dimensional assessment (2D), but also spatial one (3D). Scientific literature such as Measuring the Skin recommends for these cases scanning the surface in 3D, using the contact scanners for made imprints. Here, however, errors that may be caused by mechanical method of scanning skin relief are not taken into consideration and there is also not clearly described the material suitable for the production of custom impression. The following article focuses precisely on this issue, specifically on the implementation of the biological surface relief imprint using a silicone impression material, its 3D scanning without contact and forming an enlarged replica by rapid prototyping technology.

Published: December 2014

The paper deals with problems of computer modelling of heat treatment processes. The effect of the choice of the coefficient of heat transfer between the coolant and components was quantified. The oil Isorapid HM 277 was chosen as the coolant. Two cases of application of the convective boundary condition were studied through numerical experiment. In the first of the cases, a real functional dependence of the heat transfer coefficient (HTC) was applied on the surface temperature. In the second case, it was used constant and temperature independent values of HTC on the surface temperature. Cooling curves were obtained through numerical experiment. Derived variables such as cooling rate, the density of the thermal flows are shown in the paper. Code ANSYS was used as interpretative tool of the numerical experiment.

Flexible Manufacturing Systems provide a fast reaction possibility to the changes in production conditions. For achieving a quick responsibility of production, it is necessary to leave the traditional form of production process planning. Nowadays, most of the products are designed by using CAx software. The product design of 3D model contains not only the geometrical data of product, but it may contain a part of the process plan and technological data as well.

Topography and surface roughness is defined as a set of surface textures formed due to used machining or other production technology. It is a key factor mainly for dynamically stressed components. Greater surface roughness negatively affects the fatigue strength of component or its wear resistance.The paper deals with the visualization and processing of data obtained from a laser confocal microscope Zeiss LSM 700. Data acquired by LSM software ZEN2009 are exported in the text form of 3D coordinates of the image data points and are arranged as a set of 2D profiles with resolution 1.10-7 m. The aim is to describe an alternative method of evaluating raw data extracted from z-stack of acquired TIFF images in order to achieve higher precision and identify the topography of the scanned sample surface. Different methods of data processing have been tested to eliminate deficiencies located mainly in the parts of the scanned surface with low intensity.

Published: December 2014

This paper introduces chosen results from measuring cutting forces when end ball milling as well as combined approach to their evaluation. Such a combined approach involves Taguchi array and Response Surface Methodology while main cutting data as depth of cut and side step and cutting speed and feed rate have been taken into account. Main effects of cutting data mentioned above have been identified by means of statistical formulae expressing testing conditions of ball end milling cutters. Interactions among all the cutting conditions are capable of finding out optimized radial and axial depth of cut which are derived from the measured components of the cutting force.

FEM analysis was performed on design of experiment (DoE) according to Taguchi plan L9 (34). In order to overcome the machinability issues associated with machining of Ti-6Al-4V alloy, an attempt has been made in this study to observe the effect of friction coefficient, cutting speed, feed rate and cutting edge radius and on cutting force, temperature and power in 2D orthogonal cutting process supported through out with Third Wave Systems’ AdvantEdge. The comparison between the predicted cutting force, temperature and power at varying of friction coefficient, cutting speed, feed rate and cutting edge radius are presented and discussed. Evaluation of obtained results was processed by the statistical software Minitab 16.

Published: December 2014

Storage is one of the most important parts of logistics, which ensures storage of the products at the place and between the place of production and place of usage. Basic role of storage is equilibration and harmonization of differences among differently designed material flows. Selection of a suitable method, which monitors the storage control, is a main decision of the plant representatives. Each method is suitable for a particular materials and different types of production process. Presently, accent is placed at the modeling and simulation of monitored processes in production system. Main reason for simulation is early identification of problems and deficiencies, which could cause significant problems in a real production process.
