为了得到矩形贮液结构液.固耦合系统的振动特性,该文针对钢制矩形贮液结构的液-固耦合系统进行模态试验分析,给出了矩形贮液结构在无液体与有液体、不同顶板厚度及贮存不同液体时液.固耦合系统的前4阶固有振型和相应的固有频率,对比分析了贮存液体,顶板的相对厚度和液体密度对矩形贮液结构液.固耦合系统固有频率的影响.结果表明:贮存液体会降低贮液结构的固有频率,加大顶板厚度会使贮液结构的固有频率增大,液体密度对贮液结构的固有频率影响不大,从而为矩形贮液结构液-固耦合系统的研究和应用提供依据.

For obtaining the vibration characteristic of liquid-structure interaction system on rectangular liquid-storage structure, mode test for liquid-structure interaction system of steeliness rectangular liquid-storage structure was presented. Former four nature modes of vibration and corresponding natural frequency of liquid-structure interaction system with no liquid and liquid, with different roof thickness and the different liquid densities were obtained, and the influences of the storing liquid, the relative thickness of roof and the density of liquid on the natural frequency of liquid-structure interaction system were analyzed. The results showed that storing liquid would lower the natural frequency of liquid-storage structure, increase of roof thickness would increase the natural frequency, and increase of liquid density would have little effect on the natural frequency. The experiment provides basis for subsequent study and application of liquid-structure interaction system of rectangular liquid-storage structure.
