Wear is a major problem affecting long-term performance of orthopaedic implants. It is important to study strength and wear of the implants by evaluating orthopaedic biomaterials in vitro to achieve successful clinical applications in human bodies. This paper introduces a new type of biological implant material pin on disc (POD) wear testing device (Biotribo-POD) that can test biotribology of biological materials. A testing machine is used to simulate and predict clinical biological materials such as artificial joints wear characteristics including hip, knee and shoulder. The study focuses on implant materials. A
6-station Biotribo-POD, which can experiment with 6 pins simultaneously. It includes a pin guiding module, a motion module, a framework module and a loading module, providing multidirectional slide track shapes and variable load with a computer program. Thus influences with different motion paths can be studied.
