摘要：

This paper deals with a multi-physics shape optimization of a fuel pump permanent magnet motor implemented in an airplane wing. The goal is to reduce motor noise by working on both electromagnetic and vibration aspects. A challenge is to maintain the initial electromagnetic performances while reducing the noise. Coupling together EM simulations, vibro-acoustic analysis and optimization method, a noise average reduction of 1 dB and 15 dB for critical frequency has been obtained.
