| Abstract: | Thermally induced vibration is frequently discovered on spacecraft' solar array,which is due to the day night orbital transition.Predicting the thermal distribution is a very important step in spacecraft design.This paper investigates the thermal distribution in the space station' solar array by using finite element method.Some important conclusions have been arrived,which is instructive in engineering design. |
