摘　　要：针对枝状管在流体网络实时仿真中的建模与应用,建立了枝状管的分布式单点流体网络模型。将模型的运算集中于单个节点压力的迭代计算,基于枝状管的单输入特点设计了相应的节点压力迭代算法。以简单总管系统为例,验证了所述方法在流体网络实时仿真与模拟应用中的正确性和有效性。结果表明,采用该建模方法及迭代算法,节点压力的首次迭代计算结果产生的偏差小于5%,且整个迭代计算过程具有大范围的单调收敛性,具有很好的实时性并适合工程应用。For the modeling and application of tree-like branching pipes in the real-time simulation of fluid network, this paper established the distributed single-point fluid network model of the tree-like branching pepes. The calculation of the model was centralized into the iterative calculation of the pressure of single node, which was designed on the basis of the characteristic of single input of the tree-like branching pipes. In a simple system of mains as the example, the method presented was proved to be right and effective in the real-time simulation and simulation applications of fluid network. The results showed that, by using the modeling method and the iterative algorithm established, the deviation results of the first time of iterative calculation of the node pressure is less than 5% and the whole process of iterative calculation will monitone convergent in a wide range, which ensured a good real-time performance and is suitable for engineering applications.
