摘要
针对飞行员跳伞模拟训练系统研发需要,对人伞惯性参数进行了研究。首先,建立了人伞系统体固定坐标系,并在此基础上给出了伞衣、伞绳的惯性参数计算方法;其次,基于Hanavan人体模型,给出了人体模型各环节的重量分配、质心计算、惯性参数的计算方法;再次,基于转动惯量平行轴定理,给出了人伞系统体固定坐标系下惯性参数的计算方法;最后,给出了一个人伞典型计算案例。仿真案例显示,所提出的人伞惯性参数计算方法可以有效计算人伞惯性参数值,精确度能够满足飞行员跳伞模拟训练需要。
In response to the research and development needs of pilot parachuting simulation training system,this paper studies the inertial parameters of human-parachute system.Firstly,the fixed coordinate system of the human-parachute system is established,and on this basis,the calculation method of inertial parameters of the canopy and parachute line is given.Secondly,based on the Hanavan human model,the calculation methods of weight distribution,centroid calculation and inertial parameters for each link of the human model are given.Thirdly,based on the parallel axis theorem of moment of inertia,the calculation method of inertial parameters in the fixed coordinate system of human-parachute system is given.Finally,a typical calculation case of human-parachute system is given.The simulation case shows that the calculation method of inertial parameters of human-parachute system proposed in this paper can effectively calculate the inertial parameter values of human-parachute system,and the accuracy meets the needs of pilot parachuting simulation training.
