Design and Experimental Analysis of Knee Joint of Lower Limb Prosthesis Based on Magnetorheological Damper

A lower limb prosthetic knee joint based on MR damper is designed, and the designed lower limb prosthetic knee joint is parameterized. On this basis, build the knee joint test platform of lower limb prosthesis, collect the angle data of knee joint, and carry out the corresponding experimental research on the movement of knee joint of lower limb prosthesis. The test results show that the structural design and control system of lower limb prosthetic knee joint are reasonable, which can realize the normal walking gait of the disabled in daily life, and the designed lower limb prosthetic knee joint meets the normal needs of human body. It has certain significance and value in the field of motion control of medical equipment and lower limb prosthesis.
