Abstract :
Nowadays, a comfortable ankle prosthesis with natural walking gait for the amputee has become an important requisite. In this paper, a new kind of active ankle prosthesis is presented, which can not only help amputees walk naturally, but also reduce energy consumption by recycling. Firstly, the structure of ankle prosthesis was proposed. And then, dynamic simulation and structure parameters optimization for the prosthesis were carried out in Adams software environment. Finally, energy consumption in a gait cycle was calculated based on the dynamic simulation. We conclude that our ankle joint prosthesis can greatly reduce the energy consumption.
