Development of a New Tribological Multi-Function Simulator

In this study, a new developed tribological multi-function simulator system, SHU-MFS is firstly introduced. By changing of the holder, a hip joint simulator and a POD tester can be generated in the new system. The simulator is designed not only for wear tests of the total hip prostheses, but also applicable in common tribological study. As to the module of hip joint simulator, this design can be described as having the basic motion components in human hip joints. A frequency control system is developed to offer a wide range of rotation frequency so as to provide proper experiments towards different groups. In the POD part, eight precision-made pins are generated and an advanced computer system is built up to measure the friction coefficient of the test samples.
