摘要:
为研究T型压力管道结构内部流体非定常流动诱发的管道振动问题，采用流固耦合分析方法进行分析，借助有限元分析软件ADINA对输送气体介质的T型压力管道结构的进行了流固耦合数值模拟，得到了管内流体流动参数的变化以及管道应力分布规律，并预测了管道振动特性。同时，利用管道振动测试试验系统进行T型管道结构的振动特性进测试，得到压力管道耦合振动响应频率。结果表明：流固耦合数值计算的结果与试验结果能较好地吻合，流体介质的T型压力管道内存在明显的流固耦合效应，不考虑流固耦合作用结果与实验结果相差很大。
Abstract:
In order to analyze the problem of pipeline vibration induced by unsteady flow of internal fluid in T-shaped pressure pipeline, the fluid-structure interaction analysis method was adopted. The numerical simulation on the fluid-structure interaction of T-shaped pressure pipeline transporting gas medium was conducted by using the finite element analysis software ADINA. The change of internal fluid flow parameters and the stress distribution of the pipeline were obtained, and the vibration characteristics of the pipeline were predicted. Meanwhile, the experimental tests on the vibration characteristics of T-shaped pressure pipe were conducted by using the measuring and testing system of pipeline vibration, and the coupling vibration response frequency of the pressure pipeline was obtained. The results showed that the numerical calculation results of fluid-structure interaction were consistent with the experimental results. The effect of fluid-structure interaction was obvious in T-shaped pressure pipeline with fluid medium, while the results without considering the fluid-structure interaction had a great difference compared with the experimental results.
