摘要
本文得到了充液管道流固耦合4方程模型的一个同时含有泊松耦合和结点耦合的波动解析解。解析解的计算结果与实验结果吻合。通过划分定义区间,较成功地解决了在边界上产生两种不同波速的反射波与入射波迭加的问题。文中还提出了分段函数的一种逻辑表达方式,用它来处理分段函数的运算。
In this paper,an analytical solution for the4- equation model of fluid- structure interaction in liquid- filled pipes is obtained,with the help of a new logical expresion of segmented functions.The analytical solution involves both the Poisson and junction coupling and is in good agreement with the experimental re- sults of Dundee University.The new logical expressions of segmented functions are verified to be successful and efficient.
