Abstract;The development of technology to predicting sloshing noise from a fuel tank was approached from the aspects of simulation and experiment. First, an acceleration and deceleration from a vehicle was applied to a bench-mounted fuel tank containing fuel to generate a sloshing noise, and the physical parameters that were closely correlated with the sloshing noise were extracted. Next, computer simulation using an explicit transient solution method was performed to reproduce the fluid motion behavior in the tank, and a study was performed whether or not the physical parameters obtained from the experiment was useful for predicting sloshing noise. As a result, it was confirmed that the sloshing noise was caused by fuel striking localized areas of the inside wall of the tank. It was found that the occurrence of sloshing noise could be predicted by analyzing the impulsive pressure rise at the inside wall of the tank. A comparison of the computer simulation results with the experimental results showed that the experimentally observed impulsive pressure rise could be accurately reproduced by simulation as well, thus enabling the occurrence of fuel sloshing noise to be predicted.
