Abstract: The intelligent knee prosthesis structure was designed and the dynamics model of the lower limb prosthesis system and hydraulic damper model were established in this paper. The flow area which adjusted the damping torque was identified through the combination of hydraulic damper model and dynamics model. The comparable analysis was done based on the Matlab simulation of damping torque curve with theoretical curve. The damper opening of the specific speed was determined. The trend of the knee joint moment curve produced by the hydraulic damper is consistent with the theoretical moment curve under different flow areas. The damping moment of hydraulic knee joint can be controlled by adjusting the flow area. The proposed damping torque model can provide effective guidance for the determination of the flow area and have important consequences for adjustment of damping torque. Providing theoretical model of the damping torque control for the hydraulic intelligent knee prosthesis.
