Analysis of Artificial Hip Joint with various Defects during Walking
The analysis is done on a prosthetic joint of described dimensions which carries a joint load of 4.9BW and muscle forces of 1.79BW and 0.6BW of abductor and adductor muscles respectively. A walking motion involving 310 flexion to 110 extension has been applied at 50 steps for materials CoCr forged, SS316L, Titanium alloys – Ti-6Al-4V, Ti-35Nb-7Zr-5Ta for joint and UHMWPE for acetabular cup. The method used here is Finite Element Modelling and Analysis. The 3D model of the prosthetic hip joint has been done by using advanced CAD software. This constrained model is imported in FEA software for solving and plot of results. The response to static and dynamic loads caused during walking are determined. Results obtained for different combinations of materials have been compared to select optimum design for which the Titanium alloy Ti-6Al-4V is best suited due to its high Young’s modulus and lightness in weight.
