By the Ball Screw Drive a New Initiative Knee Joint Structure Design


Article Preview

Passive AKPs being currently in use do not respond to the needs of daily living activities of many amputees. For example, it is difficult to climb stairs with natural posture and to adjust the stiffness of the knee joint motion during the swing phase. Therefore this paper proposes the instantaneous center with variable rotating multiaxial knee, the multiaxial four league rod mechanism composition, have bionic similarity, involving active knee mechanism design and experiment. Artificial limb main part is through motor based on active control knee flexion knee actuator.This paper was designed by the ball screw electric a new initiative knee institutions.
