Effect of Support Parameters on the Vibrations of a Cracked Rotor Passing Through Critical Speed

The aim of the present study is to improve the efficiency of a rotor bearing system for passing through critical speed. The current study assesses the influences of support parameters on the cracked rotor response for passing through critical speeds. The actual breathing mechanism of the transverse crack is addressed herein. The Finite element model is developed for more realistic analysis. The Newmark-β method to solve the nonlinear lateral vibration of rotor-bearing systems is approached and the effects of various parameters are shown.
