将轴承－主轴作为具有多自由度的弹性支承系统，同时引人轴承非线性支承刚度，对轴承与主轴的受力和变形综合起来进行了分析。给出了球轴承和滚子轴承数值求解方法。
The bearing - spindle as a flexible support system with more degrees of freedom, at the same time the introduction of nonlinear bearing stiffness of the bearing, bearing and spindle stress and deformation were analyzed. The numerical solution of ball bearings and roller bearings is given.
