The sloshing noise in the fuel tank after car braking would make driver and passenger uncomfortable. The transmission characteristics of a definite type of fuel tank were studied, with the method of operational transfer path analysis (OTPA). According to the installation method of the tank, an OTPA model of sloshing noise was established, regarding the bandages and anti-vibration pads as the structure-borne noise paths. Comparing the calculated value and the measured value of the spectrum of sloshing noise, we find they coincide, so the model is proved valid. According to OTPA model, the noise contribution spectrum of each path was calculated. By analyzing the vibration acceleration spectrum and the transfer function spectrum of structure-borne noise paths, some improvements were proposed for reducing the sloshing noise.
