介绍了一种新的单元刚度矩阵,讨论了主轴上零件质量的处理方法,以及频率响应、动柔度和阻尼比的计算方法,所有这些都在机床主轴部件有限元计算中得到了成功的应用。
A new element stiffness matrix is introduced. The processing methods of the quality of the parts on the spindle, the calculation methods of the frequency response, the dynamic flexibility and the damping ratio are discussed. All these have been successfully applied in the finite element calculation of the main shaft of the machine tool .
