Performance Test for Laminated-Type Prosthetic Foot with Composite Plates


Prosthetic feet with composite plates satisfy the gait requirements since they are able to provide additional energy for efficient walking when they dissipate stored elastic energy. In this study, laminated-type prosthetic foot with composite plates was designed with constant curvature and thickness according to the length, which tends to reduce the product price compared to the conventional one. Prosthetic foot was optimized using finite element analyses with ABAQUS/Standard in accordance with the performance test based on the KS P 8403 standard to improve bending characteristics in both sides such as the forefoot and the heel which are substantially equivalent performance compared to the LP Vari-Flex.
