?為及時、準(zhǔn)確地檢測隔離內(nèi)部故障，支持新一代飛機視情維修和自主式保障的實現(xiàn)，提高飛機的保障性和經(jīng)濟可承受性，必須在裝備研制一開始就綜合考慮整體診斷策略的設(shè)計，從設(shè)計的源頭保證良好的測試性。因此，在設(shè)計初期，仿真分析作為設(shè)計輔助手段顯得尤為重要。目前，基于仿真的診斷設(shè)計研究對實際診斷設(shè)計的指導(dǎo)多停留在理論階段，缺乏工程應(yīng)用的途徑及案例，使得先進的診斷策略設(shè)計技術(shù)與工程實際脫節(jié)。因此，如何將仿真分析結(jié)果有效應(yīng)用于工程實際，建立起二者之間的橋梁，是診斷設(shè)計中亟待解決的問題。筆者介紹了一種基于仿真的嵌入式診斷設(shè)計方法，并基于案例對該方法的有效性和實用性進行了驗證。該方法為仿真分析得到的最優(yōu)診斷策略在嵌入式診斷設(shè)計中的有效落實提供了思路和途徑，實現(xiàn)了建模仿真分析工作對實際工程設(shè)計的有效指導(dǎo)，可用于指導(dǎo)產(chǎn)品實際診斷設(shè)計。將測試性建模分析和EDA仿真分析手段有效結(jié)合，論述了一種基于仿真的診斷設(shè)計方法。其以測試性建模分析得到的故障一測試相關(guān)性矩陣為基礎(chǔ)，依據(jù)EDA功能及故障仿真分析，獲取診斷所需的檢測信號/參數(shù)狀態(tài)并確定信號處理方法，從而構(gòu)建得到一種故障一信號一測試相關(guān)性矩陣，用以指導(dǎo)產(chǎn)品的嵌入式診斷設(shè)計。文中基于工程案例，對該嵌入式診斷設(shè)計方法進行了詳細(xì)介紹，依據(jù)文中案例，通過適當(dāng)添加軟硬件電路，采集9個測試點上的信號，即可實現(xiàn)對案例診斷對象18種故障模式的有效檢測和隔離。該方法為將測試性仿真分析得到的最優(yōu)診斷策略應(yīng)用于工程實際提供了思路和途徑，為產(chǎn)品嵌入式診斷設(shè)計實現(xiàn)提供了有效指導(dǎo)。
