Finite Element Simulation of Soldier Lower Extremity Exoskeleton

The Soldier Lower Extremity Exoskeleton (SLEE) is designed based on the biological characteristics of the soldier movement. It is a wearable intelligent device that integrates human body with exoskeleton in order to improve the soldier's ability of load-carrying. The virtual prototype model in the UG was built, the FEA model was built, and the strength is studied of the SLEE's key parts by finite element simulation with the finite element analysis software. The control system is analyzed, gait stability control is realized using ZMP technology. The main control machine of control system comprise embedded processor and high speed digital signal processor (DSP), cooperative motion control of the actuators is realized through the CAN technology. Current research work will be helpful in further this kind of designers to select material and the frame optimization design.
