舰船消防管网水力分析及漏点诊断研究

The Hydraulic Analysis and Leakage Diagnosis Research for Warship Firefighting Piping Network

摘要: 舰船消防管网在战斗中发生战损后，如果不能及时隔离受损区域将会导致消防管网失压，因此及时找到受损位置并迅速隔离受损区域对于提高舰船消防管网生命力乃至保证舰船生命力都具有十分重要的作用。为了实现消防管网受损监测诊断，本文通过改进舰船消防管网水力计算方法，建立受损监测诊断模型，并采用SCEM-UA算法来求解该模型，并用实例验证了本文所提诊断模型的可行性和有效性。

Abstract: When the warship firefighting piping network is struck, the piping network will lead to pressure drop if the damaged zone can’t be insulated. Therefore, how to position the leakage point and in-sulate the leakage zone is very important for improving piping network’s survivability and war-ship’s survivability. Aiming to realize warship firefighting leakage detection and diagnosis, the hydraulic analysis for warship firefighting piping network is studied, leakage detection and diag-nosis model is established, and then SCEM-UA algorithm is used to solve the established model, the instance demonstrate the feasibility and effectiveness of this paper.
