Research on Inertia Parameters of Human-Parachute System in Pilot Parachuting Simulation Training System

In response to the research and development needs of pilot parachuting simulation training system, this paperstudies the inertial parameters of human-parachute system. Firstly, the fixed coordinate system of the human-parachutesystem is established, and on this basis, the calculation method of inertial parameters of the canopy and parachute line isgiven. Secondly, based on the Hanavan human model, the calculation methods of weight distribution, centroid calculationand inertial parameters for each link of the human model are given. Thirdly, based on the parallel axis theorem of momentof inertia, the calculation method of inertial parameters in the fixed coordinate system of human-parachute system is giv?en. Finally, a typical calculation case of human-parachute system is given. The simulation case shows that the calculationmethod of inertial parameters of human-parachute system proposed in this paper can effectively calculate the inertial pa?rameter values of human-parachute system, and the accuracy meets the needs of pilot parachuting simulation training.
