ペダリングに適した大腿義足開発のための機械工学的検討

抄録

The purpose of this study was to develop a prosthetic knee joint unit suitable for pedaling by modeling pedaling using four-link mechanisms and examining the link length and joint torque that maximizes crank torque. As a result, the crank torque increased as the link length became shorter. The joint torque of the simulation switched the function of flexion and extension at the singular point of the mechanism. This was shown to be reproducible by a active prosthetic knee joint unit. And the joint torque of the simulation and the joint torque of the able-bodied person were different. Also, it was suggested that the relationship between knee joint angle and knee joint torque of able-bodied person can be reproduced using a passive mechanism.
