摘要
建立了伞舱系统刚性连接和弹性连接时的数学模型,针对联盟号飞船回收系统进行了动力学仿真。分析了降落伞侧向力系数、吊带长度、降落伞和载荷质量比以及吊带性质对伞舱系统运动稳定性的影响,其结论可为伞舱回收系统的设计提供参考。
The model of the parachute-cabin system was built with the riser being of rigidity or elasticity, which was applied for simulating the system of Soyuz. The influence of the following factors on the stability of the parachute-cabin system is analyzed in this paper： the coefficient of the parachute lateral force, the length of the riser, the weight ratio of the parachute to payload and the character of the riser. The conclusions provide an important reference for the design of the parachute-cabin system.
