Abstract

Abstract:

BACKGROUND: Skeletal muscle system is the driving force to reveal the change of human body movement, and its modeling is the key technology of human body modeling.

OBJECTIVE: To establish models of skeletal muscle of human lower limb based on UG and ADAMS.

METHODS: Body size parameters of the lower limbs of six men were measured. According to the collected motion parameters of the lower limbs, ground reaction force (ground support) and electromyogram signal of lower limb muscle group, ADAMS with the dynamics and kinematics simulation was conducted to get simulation parameters, such as ground reaction force, joint force, and link point displacement. Simulation value was compared with the measured value. Finally, MATLAB was used for simulation analysis.

RESULTS AND CONCLUSION: It is concluded that the measured ground reaction force, joint angles, and link point displacement had very significant linear correlation with ADAMS simulation data. The simulation results show that a model of human lower limb skeletal muscle established by UG and ADAMS can effectively solve the tedious multi-rigid-body dynamics problems through the simulation calculation.
