Braking Process

According to the real dimension of the braking disc, the finite element modeling for three-dimensional transient cyclic symmetry during the long downhill braking is established. The distribution of the transient temperature field of the brake disc during the braking are analyzed. The variation of the friction factor combined with the temperature characteristics of the friction factor during the braking are analyzed. The analysis result show: During the braking, the temperature of the brake rises increasingly and reaches the top temperature of 316.04°C at the end of braking process, the high temperature section concentrates in the far area of the friction surface; The changes of the friction factor is relatively stable during the long downhill braking. There is no obvious thermal recession. (Abstract)

Temperature Dependences

The paper deals with possibilities of using the laser in technologies. The parametric temperature field analysis was realized by the finite element method. The analysis was run in COSMOS/M software solver. A thermal module HSTAR makes it possible to realize cases of the temperature dependences on the material properties. Material data can be entered as a function of a temperature. The thermal and physical characteristics of the polymeric materials change significantly. The output of the analysis was described by spectrograms with temperature field distribution of various materials.

With the higher speed of the car, brake disc temperature will increase sharply when emergency braking, and its performance is demanded more and more higher. According to the Heat Conduction Theory, a brake disc's Thermo-mechanical Coupling model is built using ABAQUS software to analyze the brake disc transient temperature field. The analysis results shows that there is temperature gradient along the radial direction and axial direction, the temperature of the surface nodes with braking time has a wavy change, and the simulation result can be used as the references of brake disc design and selection.

Abstract The hot-press fusing process of a laser printer is one of the principal causes for paper folding and bending deformation. In order to predict and control the deformation of paper, first, the following analysis method is proposed for the transient temperature field analysis of the continuous moving paper: discretizing the thermal analysis process, replacing the moving paper model with the moving heat source, and simulating the movement speed of paper by setting the flow boundary conditions. Second, taking the steady-state thermal calculation results of the printer in the standby mode as initial conditions, the temperature distribution characteristics of paper during the movement are obtained with the paper model placed in a whole-machine environment to analyze the transient temperature field. Third, using the method of multi-field coupling, the transient temperature field results of paper are taken as the external load of its static analysis to analyze the deformation of paper during the fusing process; therefore, the quantitative deformation results and deformation characteristics of paper after fusing are obtained. According to the results, more precise boundary conditions can be achieved by calculating the temperature field of paper in a whole-machine environment. The method of transient temperature field analysis for continuous moving objects proposed in this study can effectively simulate the movement process of paper. The results reveal the mechanism of paper wrinkle and bending deformation in the fusing process, which can be used to predict the conveying performance of paper and guide the design work of the printer.
