星敏支架是卫星主体和星敏感器之间的过渡连接,它应满足一定的安装精度要求和可靠的承载能力。文章采用有限元方法对星敏支架进行了静、动力学分析,并对分析结果进行了试验验证。根据分析与试验结果,星敏支架的强度和刚度均能满足要求,具有较大的余量。在此基础上,对支架进行了以减重为目的的优化计算与分析。计算表明,支架减重超过40%,优化方案合理可行。 Xing Min stent is a satellite connection between the main body and the star sensor, it should meet certain installation accuracy requirements and reliable carrying capacity. The article uses the finite element method to carry on static and dynamic analysis to Xing Min stent, and carries on the test verification to the analysis result. According to the analysis and test results, the strength and stiffness of Xingmin stent can meet the requirements, with a larger margin. On this basis, the optimal calculation and analysis of the stent for the purpose of weight loss were carried out. The calculation shows that the weight loss of the stent exceeds 40%, and the optimization scheme is reasonable and feasible.
