蜂窝夹层板封闭声腔的结构—声耦合特性分析
Analysis of Structural—acoustic Coupling of an Enclosure Surrounded by Honeycomb Sandwich Panel
摘要
Abstract
The structural -acoustic coupling mechanism, characteristics, effect of system parameters on structural-acoustic coupling degree and on eigenfrequency of the system were analyzed theoretically. The eigenfrequency of the coupled system was estimated. The theoretical model and calcula-tional methods were validated by comparing with available results. The influence of structural parameters of honeycomb sandwich panel on the sound pressure response in cavity was then studied systematically. The analysis results demonstrate that increase in thickness of face sheet and core is propitious to reduction of sound pressure response in cavity under the restriction of total mass and the fundamental frequency of structure.关键词
