为了检验空间遥感相机的动力学特性，需要对相机与飞船进行动力学耦合试验。为了确保相机的试验安全性，拟首先采用相机的试验模型进行动力学耦合试验，这就带来了相机试验模型的设计问题。通过对空间遥感相机的力学分析，提出了对相机试验模型的力学特性要求。利用ＵｎｉｇｒａｐｈｉｃＩＩ软件实现了模型与原型的质量等效， 并通过分析相机几何参数对相机与飞船耦合模态的灵敏度，采用经典理论解析分析法和固有频率优化法，实现了对试验模型与原型的刚度等效，使得试验模型与飞船的耦合振动和相机与飞船的耦合振动相似。该试验模型的成功研制方法，将对类似的动力学耦合试验起到一定的参考作用
In order to test the dynamics of the space remote sensing camera, a dynamic coupling experiment between the camera and the spacecraft is required. In order to ensure the safety of the camera experiment, it is proposed to use the experimental model of the camera to conduct the dynamic coupling experiment firstly, which brings the design problem of the camera experimental model. Through the mechanical analysis of the space remote sensing camera, the mechanical characteristics of the camera test model are proposed. By using UnigraphicII software, the model and prototype quality are equivalent. By analyzing the sensitivity of camera geometry to the coupling mode between the camera and the spacecraft, the classical theory analysis and natural frequency optimization are used to analyze the stiffness of the model and the prototype Equivalent, so that the test model and the spacecraft coupled vibration and the camera and the spacecraft coupling vibration similar. The successful development of the experimental model, will be similar to the kinetic coupling test played a certain reference
