Abstract Currently, the generation mechanism and influencing factors of the structure-acoustic coupling resonance phenomenon in the realm of high-speed trains have not been thoroughly examined. Furthermore, the corresponding optimization design based on the structure-acoustic theory needs to be further developed. Based on the principles of modal and mass equivalence, this study establishes a finite element model for the head car of Electric Multiple Units (EMU). The modal analysis of the structural, acoustic, and structure-acoustic coupling systems is performed where the coupling influence of internal and external sound fields is taken into account. The results of the finite element analysis show that the modal frequencies of the structure conform to the relevant design standards. The acoustic frequency at a certain order closely aligns with the structural one, providing a reference for the subsequent coupling resonance optimization. The variation of the modal parameters demonstrates the necessity of considering the structure-acoustic coupling. Finally, based on the modal analysis results, two optimization designs are implemented for the head car: the first one aims to lighten the weight with adjusting the thicknesses of various areas, adhering to the constraint of the frequency of the first-order vertical bending structural mode; the second seeks to mitigate the effects of coupling resonance where a multi-objective optimization model is formulated aiming at maximizing the frequency difference between the structural and acoustic modes and minimizing the vehicle mass.

Key words： EMU structure-acoustic coupling mode coupling resonance lightweight design multi-objective optimization
