摘　　要：针对电主轴的结构特点,利用Prohl传递矩阵法对其进行了简化建模,建立了传递矩阵方程。以某型电主轴为例,求解出轴系的固有频率和临界转速,得到其对应的主振型图。分析结果表明该电主轴具有良好的动态特性,可以满足加工需要。The structural characteristics of electric spindle was discussed,the simplified model of spindle was established using Prohl transfer matrix method. Taking an electric spindle as an example, the free frequency and critical speed of the spindle system is got, and the relative main vibration model is found out. The results show this spindle has better dynamic characteristic and meets the needs of machining.
