Abstract

Abstract:

In order to explore dynamics characteristics in multi-case of connection frame in macro/micro motion platform, a connection frame was investigated in multi-cases during motion process of the macro/micro motion platform. And then, static and dynamic analysis as well as calculation of the connection frame were studied in multi-cases. At last, some important conclusions were obtained. Stress and displacement distribution were disclosed, and the relevant change trends of the maximum static stress and displacement in multi-cases were investigated. At the same time, first six order natural frequencies and mode shapes were obtained. Vibration test results verify the validity of the simulation data by hammer method.

Key words: macro/micro motion platform, multi-case, connection frame, static analysis, dynamic analysis

摘要：

为探究宏微运动平台连接架在多工况下的动力学特性，针对宏微运动过程中的连接架进行了多工况受力分析。利用有限元方法，对各个工况下的连接架开展静态和动态分析与计算，得到了相应的应力和变形分布，并获得了连接架最大应力和变形随载荷变化的规律。通过计算振动模态，得到了前6阶固有频率和振型。利用锤击法进行测振实验，实验结果验证了仿真数据的正确性。
