| 摘 要： | 为了保证空间光学遥感器调焦机构的稳定性,基于经典接触理论利用非线性有限元分析软件ABAQUS对调焦机构进行力学特性分析。在进行等效静态分析时对调焦机构施加3000N作用力,得到结构第一阶模态为90Hz,满足空间光学遥感器结构整体模态大于50Hz的要求;动态分析时对调焦机构施加1N单位脉冲力,得出结构动能、加速度曲线和瞬态响应分析模态70.5Hz。力学特性分析结果表明结构具有良好的稳定性,为空间光学遥感器后续研制工作提供了一定的基础。

| Abstract: | In order to improve the focusing accuracy of the space optics remote sensor and guarantee the stability of the focusing mechanics,based on the classical contact theory,the misalignment finite element analysis software ABAQUS are applied to analysis the mechanics characteristic of the focusing organization.The 3000N forces are imposed on the focusing organization when the equivalent static analysis is carried on.The first step modality is 90Hz,satisfying the space optics remote sensor structure overall modal... |
