[W-VI-192] Proposal for System-level Noise/Vibration Design Process Using Transfer Functions
Modern EV power trains and other motor components must always pursue higher efficiency and output while lowering noise and vibrations. Electromagnetic force produced by the motor assembly is one major source of the noise and vibrations known to greatly impact these machines.
However, current design practices tend to tackle the magnetic design separately from the noise/vibration design, which forces engineers to repeatedly rework each design. A design process that unilaterally accounts for the magnetic as well as noise and vibration characteristics solves this problem. In addition to the significant hurdles of a new design process, these types of system-level vibration analyses also drive up computational costs. As one way to reduce the computational costs associated with vibration analyses, some are turning to transfer functions as a means to simulate system-level vibration characteristics by utilizing the underlaying electromagnetic force to obtain the vibrations.
This paper proposes a new system-level noise and vibration design process that takes advantage of transfer functions to realize designs that account for the magnetic characteristics of the motor as well as the noise and vibration characteristics of the entire system.
