Abstract
This study proposed a multibody dynamics (MBD) simulation approach for predicting
the vibration performance of electric vehicle (EV) gearboxes. Here, the
electromagnetic (EM) force excitation was considered with additional EM
simulations under discretely increasing rotational speeds to improve the
fidelity of the model. The simulation models were built with various scenarios
and included the bearing stiffness and radial internal clearance (RIC), output
torque, and EM force. The acceleration data obtained from those scenarios were
then compared to each other. The results demonstrated: (1) the time-domain
simulation represents the transient characteristics of the system, such as the
system response at critical speed; (2) EM excitation must be considered for
noise, vibration, and harshness prediction of EV gearboxes because it is one of
the main excitation sources; and (3) bearing parameters such as RIC and
stiffness should be carefully chosen as they directly affect the vibration
performance of the gearboxes. The MBD models developed in this study were
confirmed to be applicable to the early stage of product development to predict
the vibration performance of a prototype.
