Integrated and Lightweight Design of Electro-hydraulic Ankle Prosthesis
CoRR(2023)
摘要
For lower limb amputees, an active ankle joint prosthesis can provide basic
mobility functions. This study focuses on an ankle joint prosthesis system
based on the principle of electric-hydraulic actuation. By analyzing the
characteristics of human gait cycles and the mechanics of ankle joint movement,
a lightweight and integrated ankle joint prosthesis is designed, considering
the requirements for normal ankle joint kinematics and dynamics. The components
of the prosthesis are optimized through simulation and iterative improvements,
while ensuring tight integration within minimal space. The design and
simulation verification of the integrated lightweight prosthesis components are
achieved. This research addresses the contradiction between the high output
capability and the constraints on volume and weight in prosthetic devices.
