中文摘要：

在这份报纸，传送搏动的液体的二根联合管子的非线性的动态行为被学习。在二根管子之间的连接被看作一个分布式的线性弹簧。基于这考虑，联合二管子的系统的运动的方程被获得。二联合了非线性的部分微分方程，用第四顺序的 Galerkin 方法的 discretized，被一个第四顺序的 Runge-Kutta 集成算法解决。结果证明连接僵硬在联合系统的动态行为上有重要效果。它为运动二根管子打的一些参数值被发现那可能同步。

英文摘要：

In this paper, the nonlinear dynamical behavior of two coupled pipes conveying pulsating fluid is studied. The connection between the two pipes is considered as a distributed linear spring. Based on this consideration, the equations of motion of the coupled two-pipe system are obtained. The two coupled nonlinear partial differential equations, discretized using the fourth- order Galerkin method, are solved by a fourth-order Runge-Kutta integration algorithm. Results show that the connection stiffness has a significant effect on the dynamical behavior of the coupled system. It is found that for some parameter values the motion types of the two pipes might be synchronous.
