摘要
对双层壳体(壳间充满流体的同轴圆柱壳)的声辐射进行了研究.基于Flügge壳体理论和Helmholtz波动方程计算了有限长双层壳体在径向点激励下的声功率和振动速度级,讨论了双层壳体固有振动特性,比较了双层壳体与单层壳体声辐射特性.
The sound radiation of a submerged finite double shell (two concentric cylindrical shells with the
entrained fluid) is studied. Based on Flügge shell theory and Helmholtz equation, the sound power
is calculated for the finite double shell driven radially by a point force. The natural vibration
characteristics of the double shell are discussed. The comparison of sound radiation between
single and double shells is made.
