基于相关性模型的舰船系统测试性建模与分析

Test modeling and analyzing of warship system product based on relevant model

本文提出一种基于相关性模型的舰船系统级产品的测试性建模与分析方法。该方法通过建立产品任务模型、相关性图示模型等,利用一阶相关性列矢量法求解产品的相关性数学模型,进而建立产品诊断树和进行测试性预计,并为优化产品诊断策略提供建议。同时,根据舰用燃气轮机滑油系统组成和任务特征,建立其典型任务模型并进行精简,并在此基础上进行测试性建模、诊断树建立、测试性预计以及诊断策略优化等工作,为舰船系统级产品的测试性建模、分析和诊断策略研究提供新思路和手段。

A test modeling and analyzing method based on relevant model of warship system product was proposed in this paper. Through establishing the product task model and relevant graphical model, the relevant mathematical model of product could be solved by this method with the first order correlation column vector method, and then the fault diagnosis tree and test prediction of product could be done based on that, to provide a suggestion for optimizing the product diagnosis strategy. Meanwhile, according to the system composition and mission characteristics of warship gas turbine lube oil system,a typical task model was established and simplified in this paper, so that the test model, fault diagnosis tree, test prediction and test point optimization were done. And the result has provided new idea and means for the research of test modeling,analyzing and diagnosis strategy of the warship system product.
