Abstract：To exclude the interference of the bench vibration on the fuel tank sloshing noise experiment, a signal processing method was proposed. By using a multi-input/single-output system method, the independent sound sources and the typical vibration test points were identified by singular value analysis. The coherence of typical vibration and noise signals was calculated by using coherence analysis methods. The fuel tank sloshing noise was separated from combined signals of stand and tank. To quickly correct the noise results of the fuel tank sloshing bench evaluation test, a method was proposed to get the sound pressure level correction curve. This signal processing method can effectively eliminate the interference from the bench vibration during the test.
