【摘要】 介绍了动平衡精度的表示方法,利用高速加工工具系统等效动平衡力学模型,定量计算出不同工作转速下,工具系统实际动平衡精度与原始动平衡精度的关系,并通过三维分析软件UG中的SOL 103 Real Eigenvalues解算器对HSK-E63工具系统三维模型进行计算。分析不同不平衡量对HSK工具系统刀尖节点位移偏移量的影响,从而反映了其对HSK工具系统动平衡精度的影响,为实际加工生产过程中动平衡精度的选择提供了理论基础。更多还原

【Abstract】 This paper introduced the method of dynamic balance accuracy,the relationship between the actual dynamic balance precision and the original dynamic balance precision is calculated quantitatively by the equivalent dynamic balance mechanics model of high speed machining tool system. And the 3 D model of HSK-E63 tool system is calculated by SOL 103 Real Eigenvalues solver in 3 D analysis software UG. The displacement offset of HSK tool tip under different dynamic unbalance is analyzed,which indirectly reflected the influence of HSK tool system dynamic balancing accuracy,it provided a theoretical basis for the selection of dynamic balance precision in the process of production.更多还原
