| 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。

| 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. |
