Static Analysis and Experimental Study of the AMS-02 Thermal Control System

The static analysis of the Alpha Magnetic Spectrometer(AMS-02) thermal control system(TCS) was performed by applying Finite Element Method.Load cases of launch,landing and on-orbit were imposed on the AMS-02 TCS respectively.In the launch case and landing case,the coupled load analysis for the AMS-02 and the space shuttle vehicle were carried out to get the design load factors,which were equivalently represented by acceleration of gravity and angular acceleration along three coordinate axes in the AMS-02 coordinate system.By comparison,the displacements and stresses of the TCS about the predicted numerical results are very close with that of the test results.It is proved that the static analysis and the load analysis method in this paper are effective.The study in this paper can provide the basis for the final design and optimization of the structure for the AMS-02 TCS.
