Description

technical field [0001] The invention relates to the numerical calculation field of sound field prediction, in particular to a plate structure-sound field coupling analysis method, device and computing equipment. Background technique [0002] The structure-acoustic field coupling system includes the structural domain, the acoustic field domain and the coupling between the two domains. Usually, the state of the structure is described by displacement in the structural domain, and the state of the acoustic field is described by sound pressure in the acoustic field. Almost all acoustic problems are related to the structure-acoustic field coupling system. The analysis of the structure-acoustic field coupling system can provide important information for the optimization of structural parts, especially elastic thin-walled structural parts that are easily excited by sound pressure and vibrate. Therefore, The research on the structure-acoustic field coupling system has important engin...
