N2 - Twin screw air compressor will be widely used in hydrogen fuel cell commercial vehicle because of its high efficiency and strong adaptability, but its noise issue isn’t ignored. For purpose of improving the noise of the compressor, the sound field of a perforated panel muffler based on three-dimensional finite element method was firstly constructed. Then the impacts of different structure parameters on the performance of muffler were investigated. A multi-chamber perforated panel muffler with wide frequency bandwidth was proposed. The noise reduction of the muffler was verified through the experimental study. The results indicate that the resonant frequency decreases with the decrease of the perforation rate, perforation diameter and the increase of panel thickness. Increasing the perforation rate, suitable perforation diameter and panel thickness are conducive to increasing the sound absorption of resonant frequency. There is a noise reduction about 11.4 dBA in average between the inlet and outlet of the muffler when the rotational speed changes from 9000 to 15,000 rpm. When the discharge pressure changes from 1.2 to 2.0 bar, noise reductions are all above 15 dBA and maximum noise reduction is 23.9 dBA.
