In order to solve thermal deformation, the finite element numerical simulation of two kind of tilting pad thrust bearing is made for the same pad surface, and thermal deformation is made to analyze comparatively. The results show that the temperature field, the deformation field and the values of pad are similar for two different supported thrust bearing (point, line support) under the same operating condition. The pad temperature and deformation will increase with the increasing of pv values. According to the calculation conditions, the temperature field rose about 1°C, and the thermal deflection increased 0.002mm with pv value increased by 10%.

Smooth Blasting

In order to make normal rock avalanche but not have significant impact on other parts of surrounding rock and produce evident deformation in the process of blasting heading, the basic mechanical property of rocks in Xishimen Iron Mine was taken as example to analyze. The process of coupling charge blasting in the surrounding holes of smooth blasting was simulated by applying the finite element numerical simulation software ANSYS/ LS-DYNA. The result shows that the surrounding rock has smallest stress and spall normally when borehole spacing of surrounding holes is 0.6m, thus boosting the efficiency of smooth blasting.

Finite Element Numerical Simulation

This paper is concerned with the quantitative effect of design parameters on the stamping process of automobile crossbeam. The considered parameters in this paper are the friction coefficient, the die fillet radius and the blank holding force, which greatly affect the metal flow during stamping. Based on the finite element numerical simulation, the stamping shaped process of the automobile crossbeam is numerical simulated with the explicit finite element method with various parameters by dint of Dynaform software. According to the simulation results, the forming limit diagram(FLD) and the wall thickness distribution of cloud on the stamping processes are technologically analyzed, the reasons and control methods of wrinkling are also pointed out, and then the optimal parameter combination of the automobile crossbeam is obtained by orthogonal experiments. It is noted that the parametric study of design parameters such as µ , BHF and RD are very important in the process design of the complicated member.
