摘要: 根据空间柔性机构运动可靠性的特点,利用浮动坐标系和模态柔性建立了柔性机构动力学微分方程, 并给出其迭代算法的数值求解方法.研究了柔性机构运动可靠性分析仿真方法,包括一次二阶矩法和高效响应面法,特别是针对空间柔性机构运动可靠性的特点,分析了以上方法的适用性.最后,应用ADAMS软件中柔性多体动力学建模、分析和仿真功能,并结合自主开发软件工具序列响应面法S RSM(Sequence Response Surfance Method),成功地对某空间展开机构的运动可靠性进行了分析仿真.

Abstract: The dynamics differential equations of flexible kinetic mechanisms were established on the basis of using the floating coordinate system and mode flexibility according to the kinetic reliability characters of the flexible bodies on space applications. The integral and iteration algorithm was applied in the solving of dynamics equations. The reliability analysis and simulation methods of kinetic mechanisms were studied, which included the first-order second-moment method and the hi-efficient response surface method. Especially, the applicability of this method on the space flexible mechanism kinetic reliability was analyzed. The kinetic reliability analysis and simulation were successfully provided to the deployable space mechanisms on the basis of flexible multi-body dynamic modeling, using ADAMS and self-developed software S RSM (sequence response surface method).
