| Popis: | This paper presents a dynamic model to predict the rotor-bearing system's vibration characteristics using Dimensional Analysis (DA). A small increment in rotor unbalance, and radial clearance can cause multiple faults, ultimately causing catastrophic failure. Hence, this model considers the influence of rotor unbalance and radial clearance on the dynamics of the rotor-bearing system. Experimental investigation reveals the effects of multiple defects at different rotor speeds. Employed Response Surface Method (RSM) correlates the clearance, unbalance, and rotor speed. Comparing experimental results with the RSM and DA indicates the effectiveness of the proposed methodology for condition monitoring of high-speed machinery in process industries. |
