摘　　要：为了优化某卫星的发射场总装和测试流程,避免反复装拆高温隔热屏或在卫星加注后安装高温隔热屏的高难度操作,文章提出了一种适用于1194A接口卫星的适配方案。经过对安装高温隔热屏的卫星与质测适配器的接口尺寸分析,以及对相关操作流程的分析和对比,设计了1194A接口的工艺转接环;经静力学分析和公差设计,解决了高温隔热屏下缘伸出卫星对接框下侧而与质测适配器发生干涉的问题。该适配器在某型号卫星上应用后,质测结果的称重精度为0.5 kg,力矩测量精度为0.2 kg m,满足技术要求。In order to optimize the assembly,integration and test process on the satellite launch site and to avoid the difficulties of installing and unloading repeatedly the high-temperature thermal insulation screen after the fuel adding,in this paper,an adapting scheme is proposed for the satellite with the 1194A interface,to prevent the interference between the lower edge of the high-temperature thermal insulation screen that extends out from the lower side of the satellite docking fixture for the mass property measurement.Through an analysis of the interface size between the satellite installed with the high temperature insulation screen and the MPM(mass property measurement)fixture,as well as an analysis and a comparison of the relevant operation processes,the adapter ring of the 1194A interface is designed.With the static analysis and the tolerance design,it is shown that the adapter ring can be used for docking with the fixture for the mass property measurement after the high-temperature insulation module is installed on the satellite platform.The results of the mass property measurement can meet the technical requirements with the accuracy for weighting of 0.5 kg and the accuracy for the moment measurement of 0.2 kg m.
