复杂流体管网动力学建模的一种有效方法

摘要

In the paper, the conventional transfer matrix model of fluidpipeline is modified,which is more suitable for modeling of large-scale fluid power network. A convenient method dealing with junction boundary conditions is introduced, and a unified approach to modeling of large-scale fluid pipeline network is established. The proposed method is efficient for modeling and simulation of large-scale hydraulic and pneumatic pipeline network and other engineering applications. The calculating results are good agreement with experiments.%对流体元件传递矩阵模型进行了改进，提出有效处理流体网络节点边界条件的简便方法，建立了复杂流体管网动力学建模和仿真的规范化方法，为工业应用的大型液压气动网络动力学特性分析提供了有效手段，对其它工程领域也有一定的借鉴作用。对比试验验证了方法的正确性。
