中文摘要：
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。
英文摘要：
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 .
