摘要
Abstract
For a thermal analysis requirement in the pre﹣design phase, a simplified thermal analysis method is presented, which applied to microsatellites with well﹣internal thermal coupling.The method separates thermal analysis in two parts: steady﹣state temperature prediction and temperature variation prediction.A thermal analysis within hours could be realized with accurate results.Comparison with numerical simulation analysis based on physical model and temperatures in thermal balance test,the deviation of simplified thermal analysis could be less than 3℃,which meeting the demand in engineering calculation.The simplified thermal analysis could reflect the thermal distribution in microsatellite and supply references in the pre﹣design phase of microsatellite.关键词
