Introduction Squeaking of ceramic-on-ceramic bearings in artificial hip joints has been reported occasionally in the past and more frequently in recent years. It is caused by vibrations of the participating components in the audible range. Energy from the kinetic movement is transferred through the tribological system between the ceramic surfaces to structural vibrations – a process called friction induced vibrations [Akay, 2002] [Ibrahim, 1994]. Interface conditions between the components… CONTINUE READING
