Reducing Resonance in a Motor/Axle Model
February 2023
Skills Utilized: MATLAB, Simulink, Technical Communication, Data Procurement and Analysis
My team and I were given a motor/drive-axle system that was modeled after a quarter hybrid vehicle model that was experiencing low frequency resonance when changing speeds, especially during active braking. Our team was tasked with:
Reproducing the braking resonance and response
Investigate existance and effect of non-linearities due to friction
Develop and validate a linearized and nonlinearized model of the motor/drive axle
Propose 4 options to reduce resonance amplitude by 30%
