高速电主轴动态特性仿真分析

在有限元软件ANSYS中对某高速磨削电主轴直接进行动力学有限元三维建模，并通过对模型较精确的单元网格划分，利用ANSYS结构动力学模块对电主轴的主轴部件进行模态分析和谐响应有限元仿真，计算了主轴前六阶的固有频率、临界转速和振型等动态特性，并进一步对主轴前端面的动态响应位移做了研究分析，结果验证了主轴结构设计的合理性，同时也为电主轴更深层的动态特性分析提供了重要参考。

Simulation Analysis of Dynamic Characteristics for High Speed Motorized Spindle

Set up the three--dimensional dynamic finite element model for motorized spindle in AN- SYS software directly and carve up element of the model accurately. Using ANSYS for motorized spindie＇s modal analysis and harmonic analysis, calculate natural frequency of spindle before six rank. critical speed and vibration modes. And further study the frequency of spindle dynamic response of the front face of the displacement. The result prove the structure design of the spindle is rational and take a significant reference for the motorized spindlers dynamic characteristics analysis.
