| 摘 要： | 基于剪切悬臂梁理论建立了矩形贮液结构的液固耦合振动方程．通过数值算例，求得满液时结构的耦合振动特性，并与无液时的振动特性进行了对比．结果表明：液动压力对频率的影响不可忽视，对振型的影响不大．为矩形贮液结构的设计计算提供了理论依据．

| Abstract: | In accord with shearing cantilever beam theory,the vibration equation of the rectangular liquid storage structures with liquid-structure interaction has been established.According to the numerical calculation example of the rectangular liquid-storage structures,the vibration characteristics of those with full liquid have been obtained and compared with the conditions without liquid.The results show that the influence of the liquid dynamic pressure on the vibration frequency can not be ignored and the influe... |
