第三讲数控机床主轴组件设计（之四）大连理工大学戴曙九、主轴组件的刚度计算主轴组件的刚度，可以用有限元法或传递矩阵法结合迭代借助电子计算机进行计算。为了便于使用，今介绍一种简化的近似计算方法。为此，首先应把主轴组件简化为一个均匀截面的简支梁模型。１．主... Lecture 3 CNC Machine Tool Spindle Unit Design (Part 4) Dalian University of Technology Dai Shujiu, Stiffness of Spindle Unit The rigidity of the spindle assembly can be calculated by means of finite element method or transfer matrix method combined with iteration by means of an electronic computer. For ease of use, this article presents a simplified approximation method. To this end, first of all, the main shaft assembly should be simplified as a uniform cross-section simply supported beam model. 1. the Lord...
