Structure Design and Motion Simulation of a Microprocessor-Controlled Prosthetic Knee

Conference paper
Part of the Lecture Notes in Electrical Engineering book series (LNEE, volume 527)


Prosthetic knee is the most important component of lower limb prosthesis. This work aims to design a novel knee joint prosthesis and provide theoretical model of the hydraulic microprocessor-controlled prosthetic knee. The intelligent knee prosthesis with hydraulic damper is designed. Innovative valve structure is proposed to realize damping adjustment with single motor. The dynamics model of the lower limb prosthesis is established. Motion simulation is done to verify the correctness of the knee joint structure. The flexion and extension damping can be adjusted continuously and independently. The simulation shows that the motion of the knee joint is steady. It means that the structure of the knee joint prosthesis is reasonable.
