The analysis of dimple geometry on artificial hip joint to the performance of lubrication
This research analyzed the effect of applied surface texturing on bearing component of the artificial hip joint due to lubrication performance. The main contribution of the paper was explaining the significant role of adding dimples in artificial hip joint surface bearing who can probably decrease f...

This research analyzed the effect of applied surface texturing on bearing component of the artificial hip joint due to lubrication performance. The main contribution of the paper was explaining the significant role of adding dimples in artificial hip joint surface bearing who can probably decrease friction interaction on the acetabular liner and femoral head that impact on improving wear resistance. This is achieved by analyzing the geometric variation (shape and diameter) of the dimple to the performance of lubricating metal-on-metal artificial hip joint bearings under normal walking conditions. The research method focused on numerical analysis using the Fluid-Structure Interaction (FSI) simulation method which reviewed the solid and fluid structure. From the simulation results, it can be seen that the variation of ellipse dimple with a diameter of 80 μm has the best lubrication performance, which is indicated by the largest hydrodynamic fluid pressure of 0.915 Pa, the smallest solid pressure is 0.433 Pa, and the largest lubricant thickness is 22.672 μm. |
