Taking the manufacture of alpha magnetic spectrom-eter for a large scaled international cooperation physical experiment as a background, the structural analysis method of thermal control system (TCS) of a spacecraft was studied. Utilizing the large finite element analytical software NASATRAN the stresses of key compo-nents of thermal control system were analyzed. According to the checkout criterion provided by NASA the strength checking and in-stability checking were carried out on the thermal control system, and corresponding safety allowance value was obtained through cal-culation. The result of computation showed that this structure was safe. The structural analysis method stated in this paper provided helpful references for the analysis of other large spacecrafts.
