摘要

In order to obtain a knee joint actuator with small volume, light weight and easy control, we analyzed the advantages and disadvantages of the knee joint actuators, the motion laws and motion forms of the human knee joints. We designed an exoskeleton knee actuator actuated by parallel four bar linkage. The motion of the knee joint of the exoskeleton adopts parallel four-bar linkage to ensure the linear motion of the knee joint while reducing the volume of the whole actuator. In this paper, we analyzed the kinematics of parallel four-bar linkage, and the motion characteristics of the mechanism, simulated the whole knee actuator, drew a diagram of the relation between the rotation angle of the knee joint, angular acceleration and screw displacement.
