To address the issue that eliminating a peak value of sound pressure level in the noise transfer function during the optimization of vehicle body noise transfer function for vehicle preparation can easily lead to new peak values of noise sound pressure level,an optimization method for vehicle body noise transfer function with the introduction of control variables is proposed.Taking the cab of a certain model as the research object,an optimization model is constructed,with the thickness of the structural panels in the cab as the variable.The proposed algorithm is used to iteratively optimize the relevant parameters.The results show that this method effectively reduces the peak value of sound pressure level in the noise transfer function within the target frequency band.
