不同约束模型下降落伞-返回舱系统运动特性分析

建立了球铰链约束、单点吊挂约束、倒“Y”型约束三种约束模型,并对某型号舱-伞系统稳定下降过程的运动特性进行仿真计算,给出在三种约束模型下,系统运动参数随时间、高度变化的对比曲线图,并对仿真结果进行分析。计算所得结论可为降落伞-返回舱系统进行运动特性分析时简化约束模型提供重要参考。

The Kinetic Characteristic of Parachute-Return Capsule System for Different Confinement Model

Three kinds of math equations were built for spherical hinge,single point connection and inverse "Y" suspension confinement models.The three different methods were then applied for calculating the kinetic characteristic of parachute-return capsule system in stabilized descent process,the contrast curve of system kinetic parameter changed with altitude or time were gotten,meanwhile,through analyzing the simulation result,The conclusions given in this paper can supply important reference for simplified confinement.
