在环境噪声控制中,设计对称形式或非对称形式多层复合板时,引用相应的等效抗挠刚度后,可把多层复合板的求解简化为相应的匀质板问题,将简化多层复合板的设计计算,在环境噪声控制中具有较大的实用价值。
In the design of symmetrical or asymmetric multi-layer composite boards, the corresponding equivalent flexural rigidity can be simplified in the environment noise control to simplify the multi-layer composite board to the corresponding homogeneous board problem. The simplified multi-layer The design and calculation of the composite board has great practical value in the control of environmental noise.
