Design development and analysis of pylon prosthesis through reverse engineering

Abstract

There have been significant advancements in artificial limbs called prosthetics. People with leg amputations may find it easier to move around with the aid of prosthetic legs or prosthesis. An artificial device known as a prosthesis or prosthetic implant replaces a missing bodily component that may have been lost due to trauma, illness, or a birth defect (congenital disorder). Prostheses are designed to replace the missing body part's lost functionality. They imitate the way a leg works and occasionally even how it looks. While some prosthetic limb users still use a cane, walker, or crutches to walk, others can do it without any assistance. To permit an amputee and to rehabilitate to a healthy locomotion its intended to develop an economical pylon prosthetics using CAD and FEA software. Nine combinations of three metal Titanium, Stainless steel and Aluminium for prosthetics specimen are developed using manual measurement and 3-D measurement. For each nine combinations the stress, strain, analysis is conducted and compared among the combinations to get an optimized model of metal combination with a maximum stress of 1.643e + 07 N/m2 which is near to the maximum stress of existing model 2.023e + 07 N/m2. This re-developed model is compared with the existing model to produce an optimized model that could meet the requirements of an amputee.
