舰船耗散性管网系统受损评估方法

摘要

Because the monitoring of the ship' s dissipative pipe network is different from that of the atmospheric pressure closed pipe network,and instantaneous changes of relevant parameters make the fast identification and evaluation on the damaged pipeline difficult,the static model of the ship' s dissipative pipe network system is established.Based on the model,the running of the ship pipe network is simulated,and each mode data set of nodes is acquired.The fuzzy theory method is used to evaluate the running state of the pipe network,ard the membership of the fuzzy clustering is adopted as a parameter to evaluate the damage of the pipe network and locate the damage point.The test results show that,by this method,the damage of the ship's dissipative pipe network can be located and evaluated easily,quickly and effectively,and the visual evaluation result can be acquired.%鉴于对舰船耗散性管网的监测有别于常压封闭管网,其相关参数变化的瞬时性使得对受损后管网的快速辨识与评估存在一定困难,建立舰船耗散性管网系统的静态模型.基于该模型,对舰船管网的运行进行模拟并获得相应节点的各模态数据集.利用模糊理论对管网的运行状态进行评估,并以模糊聚类的隶属度作为参数来评估管网受损情况及对破损点进行定位.测试表明:该方法能够简便、快捷、有效地对舰船耗散性管网受损进行定位和评估,并获得直观的评估结果.
