本文用能量法研究了覆盖粘弹性阻尼材料的环肋圆柱壳在流场中的声辐射特性，将阻尼材料用耗散的无质量弹簧来处理，讨论了阻尼材料的刚度和损耗因子对壳体声辐射的影响。
In this paper, the acoustic radiation characteristics of a ring-stiffened cylindrical shell with viscoelastic damping material in a flow field are investigated by energy method. The damping material is treated with a dissipative massless spring. The effects of damping material stiffness and loss factor on the shell The impact of sound radiation.
