Abstract

Rotor Dynamics is important for the analysis of vibration in a rotating structure under mechanics. Rotating structure are widely found in industrial setting, and it is important to have proper analyzing of machinery to avoid catastrophic event. Rotor dynamics characteristic can be determined with aid of Finite element analysis to monitor and diagnose the potential failure due to vibration. The aim of this project is to analyze the effects of design parameter on dynamics properties of a rotor-bearing system and identify the characteristic of vibration on a rotor modal with mode shape, Campbell diagram and critical speed. This project starts with modelling of a simple rotor modal and carried out with applying boundary condition and forces to observing the behavior of the rotor system. The rotor modal is later analyzed with double disk and dynamics properties is observed. The mode shape, Campbell diagram, critical speed and whirling motion has been identified. The critical speed should be avoided to prevent maximum amplitude and failure of rotor. The critical frequency at higher speeds at shaft should be passing through quickly to prevent catastrophic events.
