深孔磨削电主轴临界转速与刚度的计算研究

Research and Calculation on Critical Rotational Speed and Stiffness of Motorized Spindle Applied to Deep Hole Grinding

基于传递矩阵法与有限元法分别对深孔内圆磨用电主轴的临界转速与刚度进行了计算,得出了两种方法的差异,为电主轴设计提供依据。

Based on the transfer matrix method and finite element method,the critical speed and stiffness of the motorized spindle applied to OD and ID grinding of deep holes are calculated respectively and the difference between the two methods are obtained to provide a basis in designing of motorized spindle.
