摘要: 根据HXMT卫星的结构形式,建立卫星的有限元模型,进行静力、模态、频率响应计算,得出了最大纵向、最大横向过载联合作用下卫星各组成部分的最大应力值.对整星结构进行了模态计算和频率响应分析,得出了100Hz以内的模态频率值.结合理论分析和以往的设计经验,提出了对该卫星结构的合理改进建议.Abstract: Based on the HXMT satellite's structure, the finite element model of this satellite is developed, and static analysis, normal modes and frequency responses are investigated. The maximal stress result of every part of the HXMT satellite and the frequencies in 100 Hz are obtained. The results provide data for optimizing design of the HXMT satellite structure and avoiding synchronous vibration occurring. Considering theory analysis and past design experiences, some reasonable suggestions of optimizing the satellite structure are presented.
