Abstract

During the heavy-duty vertical lathe work and the system operation, due to the workbench oil film friction and the self-generated heat will be transmitted to the workbench through the contact surface between oil film and workbench, make workbench temperature distribution uneven and produce large thermal deformation which can affect the machining accuracy. The article on different locations of the workbench Reinforcing plate temperature field simulation analysis, based on heat transfer theory and the actual working conditions, calculating the workbench of the convective heat transfer coefficient and the initial boundary conditions, analyzing the simulation results, it reveals the influence of reinforcing plate arrangement to the workbench temperature distribution law, and get the best position of reinforcing plate on the heavy-duty vertical lathe workbench. These study results would provide a theoretical basis for the structural design of the workbench.
