Angular modeling of a rotating machine: Application to study the dynamic behavior of an electric powertrain in non-stationary conditions

Résumé

Electric engines are now moving in the direction of higher speed and larger torque to achieve higher performance. Therefore, predicting accurately the non-stationary loads and deformations during these regimes is of utmost importance. This paper aims to describe the first steps to a simplified coupled model of the electric powertrain to evaluate its dynamic behavior under non-stationary conditions considering the gyroscopic effects. The developed numerical model is based on the angular approach, which introduces explicitly the machine's free body rotation degrees of freedom, which is different from the classical approaches, where speed is generally considered constant. Integration of a simplistic novel bearing model is done to demonstrate the effects of the excitations due to the rolling element-races interactions on the dynamic behavior of the system under non-stationary conditions. The expected results will provide a base model which can be used for phenomenological analyses, for complex models of bearings, gears, and motors.
