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%.

Finite Element Numerical Simulation

The temperature field is an important aspect to study the interaction mechanism between the laser and glass. The temperature distribution on the surface of the glass that illuminated by the CO laser is numerical simulated by using the finite element method. The change of the temperature field of the target, irradiated by the laser in different time or different power, is simulated respectively, get the curve of the temperature field which reflects the temperature at the center spot changing with the action time and power.

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.
