Model based identification of internal and external damping in a cracked rotor

Abstract

The aim of the work is to develop an identification algorithm to estimate various rotor faults present in a rotor bearing system The methodology considered both external and internal damping where the external damping mainly occurs due to bearings and the internal rotating damping which appears due to rubbing of free surfaces and material hysteresis during shaft rotation in dynamic conditions Internal damping is also one of the causes of instability in rotors when the rotor system rotates...
