Optimization of Hydrodynamic Sliders for Multiple Operating Conditions

We present a new method to determine the film height distribution of the load-optimal hydrodynamic slider for multiple operating conditions. The use of the method is demonstrated in two examples, the second of which is based on the load conditions in an artificial hip-joint during a standard walking cycle. The results of this optimization may lead to an improved design of the replacement hip-joint, resulting in less wear and an improved lifespan.
