摘　　要： 在XH2130龙门加工中心的生产实践中,由于机床主轴运动产生的热变形而导致的误差严重影响了产品的精度。根据龙门加工中心机床主轴结构建立有限元模型,在不同负载的情况下,对主轴轴承的发热量进行了研究,利用ANSYS Workbench对其模拟温度场进行了分析,提出了一种利用表面对流散热优化主轴热变形的方法。研究结果表明:增大主轴表面对流散热效果对主轴热变形有明显改善。 With the rapid development of modern industry, the precision demand of manufacturing was higher. In using the XH2130 gantry machining center, the error caused by the thermal deformation seriously decreased the accuracy of the product. A finite element model was built for the main spindle system of the machine. Took convection heat dissipation into consideration and figured out the heat produced under different load. Analyze the temperature field in the way of finite element by ANSYS Workbench. Discuss the differences of the main spindle caused by the convection heat dissipation. The results showed that increase the convection heat dissipation effect can improve temperature distribution of main spindle
