Simulation and Evaluation of Prosthesis Gait Prototype

Gait analysis plays an important role in the research of prosthesis. The basic structure of prosthesis gait prototype was introduced. The nonlinear dynamic model was presented by Lagrange function and Hamilton principle. The virtual prototype model was set up based on Pro/E. Through analyzing collected gait data of healthy human beings, trajectory of hip-knee-ankle joint could be gained in gait cycle and model's kinematic, dynamic simulation could be achieved in stance and swing phase by interactive simulation of ADAMS and Matlab/Simulink. The result of simulation meets the requirements of healthy human walking and provides references for the design of prosthesis gait machine and biped robot.
