| Abstract: | Based on the simulation and analysis software AnyBody for human body modeling, the simulation and analysis method of human reverse dynamics is studied by using the test motion capture format data file C3D. The operation steps and the error analysis and its solution are presented for human motion simulation analysis of AnyBody driven by C3D. The simulation results show that the keys to realize dynamic analysis of human model are the basic parameters setting of human body model, the setting of C3D parameters, the fitting of key points, and the parameters adjustment of plantar pressure plate, and then the accuracy of inverse dynamics simulation of human body model can be improved. |
