摘要
通过对某典型电机机座进行系统的模态试验,分析不同螺栓结合面参数对机座模态的影响规律.根据所得规律,采取一种基于德国标准VDI2230的螺栓结合面建模方法建立机座有限元模型,再用Ansys对机座进行模态分析.对比仿真与试验结果表明,这种建模方法能较好地仿真螺栓结合面的振动特性.
Abstract
By modal tests for the typical motor frame, influenced of the different characteristics of bolted interface upon the modal of motor frame was analyzed. The FE model of the bolted interface was built base on VDI2230 to carry out modal analysis for the motor frame by using Ansys. Comparing the experimental data and simulation modal, showing that the proposed method of modeling the bolted interface is verified.
