输流管道流固耦合振动频域分析的传递矩阵法

Transfer Matrix Method in Liquid and Solid Coupled Vibration Frequency Domain Analysis of Delivery Pipeline

在 L－ MOC法的基础上，提出了一种求解变径输流管道在流固耦合条件下振动频域解的传递矩阵法。方法简单明了，可扩展到更复杂的管道系统。文中给出了计算，通过和已有成果以及试验比较，证明了所提出方法的有效性和正确性。

The authors have presented a transfer matrix method in analysis of vibration frequency domain under a liquid and solid coupled condition of a reducing delivery pipeline on the basis of the L－ MOC method. The method is simple and clear. And it can also be applied in a more complicated pipeline system. The paper has proved the effectiveness and correctness of the proposed method based on the calculations and comparison making between the available study results and tests.
