DEVELOPMENT AND ANALYSIS OF PROSTHETIC FOOT BY A NEW IDEA

Abstract

The procedure involved in evolving a compound that was utilized for producing prosthetic foot with mechanical characteristics and a sensible price is presented. Compound’s characteristics such as Charpy impact strength and tensile were investigated using mechanical tests. During this procedure 10% linear low density polyethylene (LLDPE) was added to 90% high-density polyethylene (HDPE). This reduced the energy impact as well as ultimate yield stress whilst elongated at break from 27% in comparison to those of pure HDPE. Prostheses properties were further studied in comparison to human foot. The analytical part indicates the static analysis outcomes by experimental as well as finite element methods (ANSYS Workbench 14). Thus, the foot was formed, and dorsiflexion was measured. Overall, the nonarticulated (HDPE and LLDPE) foot was compared to SACH foot by cost and weight. It was found that the nonarticulated foot’s weight was lighter by 2% and its cost was lower than SACH foot by approximately 60%. The nonarticulated foot has great properties, for instance a life of foot cycles (9∘ and 2,193,228) as well as good dorsiflexion in comparison to SACH foot with 6.4[Formula: see text] and 896,213 life of foot cycles.
