摘要
在卫星太阳阵展开过程中，采用有限元素法将太阳板的变形能计算出来，并引入系统运动微分方程的广义力中，通过求解系统运动微分方程，从而得到太阳阵展开的全过程和展开时间．算例表明。
In the expansion process of solar array,using the finite element method the deformation energy of solar plate was calculated,and was lead up to generalized force of differential equations of motion of system.By solving the differential equations of motion for a system all process and expansion time of solar array were acquired.Example problems demonstrate more identity with reality.
