【摘要】 讨论了铰间间隙在附件展开过程中的影响 ,由于分段线性模型可以较好地模拟间隙的变拓扑、含碰撞的动力学特征 ,将其并入到多柔体系统力学方程中 ,进而通过数值仿真详细地分析了间隙对系统的撞击力、姿态变化和附件的弹性振动的影响更多还原

【Abstract】 Discusses the effect of hinge gap on the deployment of spacecraft appendages with hinge gap, the piecewise linear model can be used to simulate the characteristic of varying topology and impact, and incorporated into the multi body system dynamics equation, and then analyzes the effect of gap on the impact force, change in attitude of the system and the elastic vibation of appendages.更多还原
