Aiming at the noise control requirements of micro electric vehicle(EV) range extender, the author designed an acoustic hood and base it to build a 3D model and make a modal analysis and acoustic simulation to analyze the effect of noise control. Verifying the design of acoustic hood is reasonable. At the same time, it’s one of the important reasons the natural frequency of the hood results in the difficulty of noise control which can supply reference for improving design of acoustic hood of range extend.
