摘要
本文研究环肋圆柱壳在周向线分布余弦简谐力激励下由振源输入壳体的功率流及沿壳体传播的功率流,分析了肋骨参数对功率流的作用,结果表明:各内力功率流分量的比例主要取决于激励频率和周向模态,而几乎不受肋骨的影响,除非该肋骨产生了波的衰减域。
The vibrational power flow excited from a circumferential cosine harmonic force with line distribution entering into a cylindrical shell with periodic stiffeners,and the power flow transmitted along the shell are studied.The influence of parameters of stiffener upon the power flow is analyzed.The ratio of power components is mainly dependent on frequency and circumferential mode,and it is rarely influenced by the reinforcement with the exception that the non-propagating bands has been established for the reinforcement.
