摘要
采用细化试验和有限元方法对某立式加工中心静刚度进行了研究。通过细化试验不仅测得了机床的三向静刚度,而且测量了主要零件的变形;对主轴箱的变形进行了细化试验,对结果进行了详细分析;测量了主轴箱滑块与立柱导轨结合面的变形,结果表明该结合面y向是薄弱环节。在Workbench中建立了机床静刚度有限元模型,通过与试验数据的对比验证了有限元模型的准确性。
Static stiffness of a vertical machining center was researched based on fine experiment and finite element method. Static stiffness of three directions and deformation of the main parts were measured. Deformation of the spindle box was measured and detailed analysis was taken. Deformation of the joint between spindle box and column was measured. The results showed that weak leak of the joint is y direction. Finite element model of the machining center was established in Workbench and accuracy of the model was verified compared with experiments.
