摘　　要：为获得卫星与运载火箭界面的动态载荷,提出了采用应变测量的识别方法:沿连接环表面设置测点,每个测点粘贴应变花测量该处应变,由升空过程中采集到的应变信号经理论分析即可辨识界面力。仿真分析证明,该方法对星箭界面动态载荷幅值的识别误差可达20%以下,能够满足工程需求,可对未来卫星力学环境识别的工程应用提供参考。In order to obtain dynami tification method is proposed based lected on the surface of the adapter c interface forces between satellite and launch vehicle, a iden on the strain monitoring. Some observation locations are se- ring to paste strain rosettes to measure the local strain. The strain signal during lift-off will be gathered to estimate interface forces by theoretical analysis. Simulation results show that the amplitude identification error of dynamic interface force is less than 20 % which can satisfy the engineering requirements. This method offers a reference for the future application to identify satellite＇s mechanical environments.
