摘要
本文研究了圆柱壳中振动功率流,分析了在不同周向波数和频率下,外载荷传递给圆柱壳中的功率流及功率流在壳体中的传播特性。理论分析表明,可以根据各内力功率流的比例来定量地确定壳体中不同波传播的成份。
The vibrational power flow from exciting force to a cylindrical Shell is studied and the power flow travelling along the Shell is also investigated. Theoretical analysis shows that the ratio of flexural, extensional, and torsional waves can be determined according to their respective power flow components.
