| Summary: | The base of heavy-duty CNC vertical lathe is one of the core components to ensure stability and precision of the lathe. Aiming to the issue of heat concentration internal structure of lathe-base, to verify the influence that velocity increasing impacts on heat generate and heat dissipation, convection mathematical model and FSI (fluid-solid interaction) heat transfer model of the base of heavy vertical lathe was established according to heat transfer theory and fluid solid interaction theory. The results of numerical simulation of heat transfer model of the base reveal the heat transfer regularity and the influence of velocity that impacts on thermal field, heat dissipation intensity of the base. Comparison result between FSI numerical simulation results and mathematical model results show that they are basically consistent. It provides a valuable theoretical basis for heavy duty CNC vertical lathe design and analysis. |
