为了改进空间CCD相机的结构设计性能,应用CAE技术对空间CCD相机进行模态分析、频率响应分析等动力学特性研究。分析计算表明空间CCD相机的自然频率足够高,一阶模态达到180Hz以上,保证了空间CCD相机在外界动态载荷低频振动作用下的动力学响应。有限元分析结果为空间CCD相机的结构设计提供了必要的指导。

In order to improve the structure design of the space CCD camera,the dynamic characteristic of the space CCD camera are studied by means of CAE technology.Some dynamic analysis（modal analysis,frequency response） is done for the space CCD camera.Analysis and caculation indicate the natural frequency of the space CCD camera is high enough;Modal 1 of space CCD camera has already reached 180Hz,which guarantees the dynamic response of the space CCD camera under the condition of low frequency vibration.The FEA（Finite element analysis）results provide the reference for the structure design of space CCD camera.
