摘要: This paper presents an innovative powered ankle-foot prosthesis with a compact parallel spring mechanism. The mechanism consisting cam and two linear springs are used to reduce the power torque requirement of actuators, while improving system energy efficiency. Herein, profile is designed generate desired rather than stroke versus angle curve. In that case, can reproduce human ankle controlled dorsiflexion stiffness. Finally, for evaluating proposed prosthesis, clinical trials on below knee amputee conducted. experimental results show performances similar normal gait.
