摘　　要：以折弯式波纹管为例,分析了流固耦合对输液管道动力学特性的影响。首先应用Pro/E和ANSYS Workbench对结构形状复杂的波纹管道进行了几何建模,通过Pro/E和ANSYS软件的无缝连接功能,在ANSYS中可以得到无损坏的波纹管模型。再利用ANSYS ICEM网格划分技术对流体和波纹管道进行六面体网格划分,得到高精度的有限元模型。最后数值分析了流固耦合作用对波纹管固有频率的影响,比较空管道、有流固耦合作用的管道、无流固耦合作用的管道三种情况下的模态,为管道振动的控制提供了重要的动力学依据。Fluid-structure interaction on the characteristics of liquid-conveying pipe system was investigated with an example of bend bellows.Firstly,a geometric model of the bellows with complex structure and shape was created by Pro/E and ANSYS Workbench software.By Pro/E seamless connectivity and ANSYS software,the bellows model achieved no damage in ANSYS.Secondly,the model was meshed using the ANSYS ICEM meshing technology,and then getting high-precision finite element model.Finally,the fluid-structure interaction effect on the natural frequency of bellows was numerically analyzed,comparing the three cases of empty pipeline,the pipeline with the fluid-structure interaction effect,and the modal without the fluid-structure effects,and the results provide an important dynamics characteristic for bellows vibration control.
