| Abstract: | A multi-rigid body dynamic modeling of human body in parachuting landing is studied in this paper.The Kane method is applied to build a two-dimensional human body dynamics model in parachuting landing impact phase.The simulation of kinetic features of human body under the impact load during the parachuting landing is performed by Matlab.The landing impact forces of body segments is then computed and the results are compared with the experiment data.The feasibility of such Kane-based method for impact simulation of parachuting landing is evaluated according to the results and modeling. |
