Simulation Experiment to Predict the Critical Friction Area of Acetabular Liner Component on Hip Joint Replacement Implant During Movement

Abstract

This paper has shown that simulation experiment to predict the critical friction area of acetabular liner component on hip joint replacement implant during movement. With the simulation method, that can help find the friction and stress area. The results of the friction simulation, the area friction of acetabular liner is 378,32 mm2 and 22,49 mm2 for the femoral head. Based on simulation stress analysis of acetabular liner shown the maximum value of von-Mises stress is 0.3994 MPa and for the femoral head is 0.3411 MPa. From the simulation results, a map of the critical contact area is obtained, which is an important reference in the development of optimal designs for the acetabular liner and femoral head components.
