摘要
为研究硬X射线调制望远镜(HMXT)卫星侧面探测器是否满足航空设计要求,对其进行动态性能分析。采用有限元方法,利用大型通用有限元分析软件ABAQUS,对侧面探测器整体模型进行了超载静力分析、模态分析、正弦振动分析以及随机振动分析,研究侧面探测器在复杂工况下的动态性能。通过计算,侧面探测器基频大于100Hz,刚性及振动性能较好,满足设计要求。研究工作为侧面探测器的优化设计提供了理论依据。
In order to study the dynamic performance of hard X-ray telescope (HXMT) satellite side detector,the finite element method is used to analyze the static model of the side detector in this paper. The paper contains the modal analysis, the sinusoidal vibration analysis and the stochastic vibration analysis by using the large-scale general finite element analysis software ABAQUS, and also the research of the side detector in complicated working condition dynamic performance. By calculation, the side detector base frequency is greater than 100Hz, rigidity and vibration performance is better, to meet the design requirements. The research work provides the theoretical basis for the optimization design of the side detector.
