Contacting surfaces can give rise to short pressure pulses (Smith shocks) when asperities interact and the resulting high-frequency vibrations, detected by accelerometers, can indicate surface distress to allow condition monitoring. Previous work had been limited by the test technique used so in this work vibration was recorded directly to computer memory to give a clearer idea of vibration patterns after failure of lubrication.
