A Rotordynamic Analysis Model for Rotor Shaft of SMART MCP

摘要

A rotordynamic analysis model has been developed in order to predict the dynamic behavior of the SMART MCP rotor shaft. The analysis model includes the journal bearing model, the gap model between the motor stator and rotor, the motor dynamic model, and the impeller dynamic model. The developed analysis model is applied to investigate the critical speeds, vibration mode shapes, and damped responses for the conceptually designed SMART MCP rotor shaft. A stability analysis of the rotor shaft is carried out on these results.
