RISEffect of Contact Area on the Wear and Friction of UHMWPE in Circular Translation Pin-on-Disk Tests
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Circular translation pin-on-disk (CTPOD) tests were performed for ultrahigh molecular weight polyethylene (UHMWPE) with a view to reproducing wear mechanisms that prevail in total hip prostheses. The contact surface diameter ...
Effect of CoCr Counterface Roughness on the Wear of UHMWPE in the Noncyclic RandomPOD Simulation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: With the random motion and load pin-on-disk (RandomPOD) wear test system, conventional and highly crosslinked ultrahigh molecular weight polyethylenes (UHMWPE) were run against CoCr counterfaces with different surface ...
Modification of a Simplified Hip Joint Simulator Into an ISO 14242-1 Compliant Design and a Comparison of Wear Test Results
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The ISO 14242-1 standard for hip joint simulator wear testing specifies a set of test conditions for the simulation of normal level walking in optimal conditions. Since some of the established simulators, such as the ...
Effect of Sliding Velocity on UHMWPE and VEXLPE Friction Against CoCr in Multidirectional, Serum Lubricated Conditions
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The recently introduced four-station friction RandomPOD device was utilized in multidirectional, circular translation pin-on-disk (CTPOD) tests. The effect of sliding velocity on friction with orthopaedic bearing materials ...
Marine Thruster Lip Seals: A Comparative Study of Frictional Behavior and a Condition-Based Monitoring Approach
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Abstract. The present work studies the behavior of a polyurethane (PU) seal and a hybrid seal design with a PU body with a polytetrafluoroethylene (PTFE) insert, and compares it to a conventional nitrile butadiene rubber ...
Thermal Behavior of a Marine Lip Seal Package
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Abstract. In this article, the thermal behavior of a marine thruster lip seal package operating fully submerged under realistic conditions was investigated. The study was conducted with a focus on developing a condition ...
