摘要

A well-designed lower limb prosthesis is necessary in order to permit an amputee to repeat to healthy locomotion. The aim of this study is to enhance the passive prosthesis to a microcontroller-based transfemoral prosthesis which was unable to reach the designated rotational speed intended for a functional use, and had low cost. The enhancement focuses on designing a new mechanism on the knee joint by using a pre-existed DC motor, a socket, and the foot obtainable from the previous design. This involves mimicking the normal limb function and to improve the range of motion of this knee prosthesis. There are some criteria that required to be achieve at this study such as the new proposed knee joint should be able to flexion up to 90° and has enough strength to bear up the amputee's body weight. Solid Works software was used to design every single part of the knee joint. Then, each part will be assembled and the mechanism of the knee joint will be simulated for visualize the imagine motion of new model of hinged knee prosthesis. The materials (Aluminium Alloy 6061, Aluminium Alloy 7075 and AISI 4130 Steel) used were chosen by taking the consideration the cost and the properties of that material. By ANSYS computer program (Finite element analysis) was performed and the conclusion were evaluated to discover if the proposed prosthesis can bear certain loads. The results were discussed and evaluated the new model that suggested by this study.
