Abstract :
The optimal design of human lower limb knee prostheses is fundamental in order to restore the lost functionality and aesthetic aspect of the amputee’s locomotion. The four-bar linkage is the most widespread mechanism, since, despite its simplicity, it allows the prosthesis to be sufficiently stable and, to replicate the natural motion of the joint with a sufficient accuracy. This work presents an optimization procedure for the synthesis of a six-bar linkage for knee prosthesis and its comparison with four-bar linkage counterpart. Different form of six bar linkages, such as Stephenson and Watt mechanisms are considered and optimized.
