摘　　要：将空气的影响视为附加在电池阵上的广义质量 ,用数值方法模拟了航天器太阳能电池阵在地面试验空气介质中展开时的动力学过程。电池阵运动诱导的空气流动采用了切片方法进行二维流场分析。电池阵在不同姿态下运动时的附加质量是在此基础上作出适当修正后得到的。分析结果表明某型号电池阵在地面和太空展开时间的差异超过13 %。Dynamic procedure of deployment of a solar array in the ground environment was simulated by numerical method,where the air influence was regarded as added generalized mass.The airflow induced by the motion of the array was analyzed in a two_dimensional section.Then,the added mass was calculated with certain modification.Results show that the deploying time of array on the ground is 13% longer then in the space.
