| 摘 要： | 针对无旋、无粘和不可压缩的理想液体,根据Winkler弹性地基上矩形贮液结构的液-固耦合振动分析模型,通过引入无量纲参数建立了矩形贮液结构的液-固耦合系统的振动方程。为简化计算,根据梁的振型函数和频率方程,将三维问题转化为一维问题来处理,利用振型函数的正交性求解了Winkler弹性地基上矩形贮液结构的液-固耦合振动频率。最后,为便于工程应用,结合工程实际讨论了无量纲参数对矩形贮液结构液-固耦合振动频率的影响,从而为以后工程结构中矩形贮液结构的设计计算提供了理论依据。

| Abstract: | In connection with the irrotational,inviscid and incompressible ideal liquid,and according to a liquid-solid coupling vibration analysis model of rectangular liquid-storage structures on a Winkler elastic foundation,the vibration equation of rectangular liquid-storage structures considering liquid-solid coupling is established by introducing dimensionless parameters.In order to simplify the calculation,the three-dimension problem is transformed into the one-dimension by the mode shape function and frequency... |
