摘　　要：热稳定性用来衡量星敏感器光轴指向抵抗温度变化影响的能力,常用试验及仿真的方法进行分析验证.仿真方法因其高效率、低成本、可贯穿产品设计全周期等优点,已成为热稳定性分析验证的重要手段.开发了一种热-力-光联合仿真分析的方法进行星敏感器热稳定性计算.该方法集合了热分析、变形分析、成像仿真及热漂移计算等多项仿真分析过程.以某高精度星敏感器为例,进行了热稳定性计算,结果表明了该仿真方法的有效性.Boresight axis thermal stability indicates the star sensor＇ s capability to anti thermal change. Ground experiment and numerical simulation are the main approaches to analyze and verify this key per- formance. The simulation method is the primary one that can be used during the whole design period. An integrated method named thermal-structural-optical analysis approach is developed to analyze the thermal stability of star sensor. This approach includes thermal, structural, optical analysis and thermal drift cal- culation. A high accuracy star sensor＇ s thermal stability is analyzed as an example. The results show the efficiency of this integrated method.
