摘要
采用多刚体模型研究了降落伞的拉直过程。在动力学模型中将引导伞、伞包、拉出的伞绳及回收物处理为开链式多刚体 ;在仿真算法中提出了求解绳段间约束力的n阶递推算法。利用该模型可以研究降落伞拉直过程中的“绳帆”现象。
A numerical simulation of parachute deployment is examined by multi rigid body model. The parachute system is regarded as a chain multi rigid body. An order n recursion algorithm is constructed to resolve constrain between ropes. The model can be used to study the 'Line Sail' of parachute deployment.
