Finite Element Numerical Simulation

In this paper, 3D finite element numerical simulation was used on the flow in the XXXX melt pump with POLYFLOW. By numerical simulation analysis on the flow field in the melt pump, distribution characteristics of pressure, flow velocity vectors and shear rate in the melt pump were obtained. Finally, the effects of inflow rate on the pressure difference between the exit and the entrance of the melt pump were investigated by analyzing the pressure field of the melt pump, which could be used to guide the design of melt pump and the plastics molding process.

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.
