With increasing demands for product quality, and the performance of assembly equipment plays a decisive role for product quality, national experts and scholars conduct in-depth research on the performance of the assembly equipment. In this paper, a research simulation on hydrostatic bearing performance of heavy-duty vertical lathes DVT(digital vertical tool) 500 is carried out by using finite element software FLUENT to simulate the fluid pressure field and temperature field distribution of sector oil recess at different work platform rotational speed. The law of these field distributions is also obtained. The results show that: the rotational speed of the work platform has a greater impact on pressure field and temperature field of gap fluid flow. Numerical results can reflect the true hydrostatic bearing fluid movement, the actual simulation results provide a theoretical basis for optimization design of the Engineering hydrostatic bearing oil cavity.

Based on heat percolation theory and thermal coefficient equation of various layer-compositors, the effective thermal conductivity of silicone carbide（SiC）synthetic material was obtained, and the effective heat capacity under the complicated thermal effect in the process of raising temperature figured out in the present investigation. Based on the experimental results and using the finite element numerical model of nonlinear dynamic heat transfer process, the temperature field in SiC synthesis furnace was simulated by open source finite element software-FECsoft. And the dynamic laws of temperature distribution and thermal gradient of the furnace, the relation between the furnace core’s temperature and the energy consumption and output were obtained. Based on the above analysis, some measures to save energy and increasing output of the silicon carbide synthesis furnace were proposed in this paper.

In the operation process of permanent magnet governor, the temperature rises due to eddy current loss, and demagnetization of permanent magnet occurs at high temperature. The numerical simulation of fluid flow field and temperature field was carried out with the method of computational fluid dynamics (CFD) and ANSYS-Fluent software. And then we improved the structure of permanent magnet governor on the basis of analysis of the flow field and temperature distribution. The result indicates that the flow of improved structure increases, and temperature drops 46.°C, fulfilling the desired temperature range of permanent magnet can bear, which provides a theory basis for the design of ventilation-cooling structure of permanent magnet governor.
