摘要
本文以一无限长弹性圆柱壳为研究对象,分析其自由振动特性及壳体中各内力传播的功率流,研究管壁接头对入射波的影响,从能量流的角度分析其振动控制效果.
The dispersion behavior of free waves in an infinite cylindrical elastic shell is investigated. An equation which determines the vibrational energy flow carried by different internal forces is derived. The characteristics of propagation waves are discussed from the view point of energy flow. The effect of wall joint on the propagation of power flow is analysed.
