Morton effect
WebJul 27, 2024 · Morton effect is a synchronous vibration phenomenon that results from journal surface temperature difference caused by viscous shearing within lubricant film. The journal surface temperature difference results in temporary rotor thermal bending, which leads to an increase in rotor vibration. WebThe Morton Effect in the rotor - bearing systems may lead to an unstable operation. Up to the present, most of the established research efforts have been focused on the overhung rotor systems. In this dissertation, a systematic study on the Morton Effect induced instability in mid-span rotor systems is presented.
