摘要:

基于经典层合板理论,计及加强筋弯曲及扭转运动影响,建立无限大正交加筋层合板传声损失的理论模型.采用空间谐波展开和虚功原理的方法,推导出正交加筋层合板的传声损失计算公式,并将计算结果与简化模型和板梁组合模型的计算结果进行对比,结果吻合良好,验证了所建模型的有效性及广适性.最后,数值分析了层合板铺设方式、铺设角度、刚度、材料损耗因子和加筋间距等参数对结构隔声性能的影响.

Abstract:

A theoretical model of sound transmission of an infinite orthogonally stiffened laminated plate was developed to investigate the sound insulation performance based on classical laminated plate theory, taking into account the effects of the bending and torsional movement of the stiffener. Then, by using the space harmonic expansion and the principle of virtual work, the sound transmission loss formula was derived. By comparing the predictions of the presented model with existing results of the simplified model and the platebeam combined model, the validity and feasibility of the proposed model was qualified. Finally, the influences of laying mode, angle, stiffness of layers, material loss factor and spacing of orthogonal stiffeners on the sound insulation performance were investigated by numerical calculation.

 

Key words: classical laminated plate theory, orthogonally stiffened laminated plate, sound insulation
