| 摘 要： | 研究了充液环肋圆柱壳结构的耦合振动特性。基于Love壳体理论,考虑壳体内部完全充液,采用波动法建立充液环肋圆柱壳耦合振动的频率特征方程,得到了不同边界条件下的耦合频率值。通过与已有文献数据对比,验证了该文研究方法的有效性和正确性。最后通过算例,分析了充液因素、环肋参数、边界条件、壳体几何参数等对充液环肋圆柱壳耦合振动的影响。

| Abstract: | The vibration characteristic of fluid-filled cylindrical shells with ring-stiffeners is studied. Theoretical formulation is established based on the Love's shell theory. The shell eigenvalue governing equation is derived with the consideration of fluid-filled property, using a wave propagation approach. Then the coupled frequency of the cylindrical shell with different boundary conditions is obtained. The present analysis is validated by comparing the results with those in pertinent literatures. The results are presented on the influence of fluid-filled characteristics, stiffening parameters, boundary conditions and the influence of geometrical dimension. |
