包含动态摩擦的管路分段集中参数键合图模型研究

Investigation into bond-graph model of sectionalized-centralized parameter of a pipeline with dynamic friction

本文首次提出了包含有动态摩擦的管路分段集中参数模型。此模型以一般管路分段集中参数键图模型为基础，通过与分布参数模型和管路特征线法的对比研究，在模型中增加了动态摩擦项。用与分布参数键图模型仿真对比研究的方法，确定了动态摩擦系数。此模型适合工程应用。

This paper puts forward firstly the model of sectionalized-centralized parameter of a pipeline with dynamic friction. The model takes the bond-graph model of sectionalized-centralized parameter of a general pipeline as the basis, compares with distributed parameter model and the method of characteristic in pipeline, adds in the dynamic friction term. And the dynamic friction coefficient is determined by simulation and comparison.
