The simulator unit allows the simultaneous independent three angular motions: flexion/extension, abduction/adduction, and internal/external rotation, with the periodic application of axial load on an implant according to ISO 14242 standard. All angular displacements are executed with high precision that is enabled by the implementation of rotary encoders. The fluid test medium fills a flexible bag surrounding an implant and is in constant circulation under controlled temperature. This ISO hip joint simulator is designed for in vitro wear testing of acetabular cups against ceramic femoral heads of hip implants in fluid environment. The simulator can be used in combination with Axial-Torsional Testing Machines.

Application example: Servohydraulic simulator for wear testing of hip implants integrated in a servo hydraulic dynamic testing machine.
