In this paper, the effect of dynamic coefficients of different bearings types on the dynamic response and the frequency of maximum response of rotor bearing system have been studied. The ANSYS Mechanical APDL 18.0 was used to model rotor with different bearings types. MATLAB software has been used to achieve the analytical solution. The results showed that the using of ball bearing, roller bearing or self aligning bearing with fluid film journal bearing strongly increasing the dynamic response amplitude and slightly increasing frequency of maximum response compared with the using of journal bearing to support rotor while using ball bearing with roller bearing have insignificant effect on the dynamic response and frequency of maximum response also using of self aligning bearing with ball bearing or roller bearing strongly decreasing the dynamic response and slightly decreasing the frequency of maximum response and using the self aligning bearing with others bearings types give the misalignment self-overcoming feature.Refference:
