Abstract |
|
In this paper, nonlinear dynamic motion analysis for cylindrical roller bearing with unbalanced rotor at high speed operation were evaluated. Cylindrical roller bearings are utilized for high radial load and speed. At high loading condition & speed a small amount of unbalanced weight may significantly affect the dynamic motion behavior of rotor system. Also, parametric vibration is one of unavoidable vibration characteristics of roller bearing which is there for thermal compensation. Thus, present research paper is focusing on study of nonlinear behaviors of cylindrical roller bearing at high speed with unbalanced forces and variance compliance as non-linearity. Experimental evaluation for proposed system has investigated in this paper with FFT and observed different harmonic, sub harmonic & super harmonic responses. |
