Impact Testing of New Athletic Prosthetic Foot

Abstract

No artificial limb can replace what is lost. However, aggressive rehabilitation and appropriate prosthetic provision will enhance the ability of injured individuals to pursue athletic activities once again. To design and manufacture an athletic prosthetic foot that can perform at the level of professional athletes, it must pass some tests to improve its suitability and comfort ability to use, one of these tests is the impact test. In order to test the suitability of the manufactured athletic prosthetic foot, impact foot tester were designed and manufactured for this purpose. Impact test simulates the response of the foot during running and calculating the peak force. This paper presents the results of tests designed to (a) measure the loads and loading rates. For this purpose, tests the impact plate was instrumented with a load cell, the pendulum with proximity sensor. Peaks load-time response was observed with an event duration of about 30 ms.
