In this paper, the acceleration booming noise problem of a pickup truck is taken as the study object, the excitation source is determined as the powertrain by analyzing the test data, and the gearbox mount contributes the most to the booming noise by using the spectrum peak correspondence method. Through the acceleration mobility test and mode test, combined with the Computer Aided Engineering (CAE) simulation analysis method, the problem was determined to be that the mode of the whole frame led to insufficient z-directional dynamic stiffness of the gearbox installation point. CAE simulation method is used to conduct virtual verification of the optimization scheme, and the final feasible and effective design scheme is determined. Finally, the effectiveness of the optimization scheme is verified by subjective evaluation and data test.
