摘要: 為了滿足地鐵車輛使用的小型電器設(shè)備在加速試驗過程中的在線電性能參數(shù)測試的需求,通過對傳統(tǒng)的小型電器設(shè)備在線測試電源、測試設(shè)備及數(shù)據(jù)處理系統(tǒng)進行改進,提出了一種基于加速試驗的地鐵車輛小型電器設(shè)備在線測試系統(tǒng)。針對地鐵車輛小型電器設(shè)備對電源系統(tǒng)的特殊要求提出了具有交直流轉(zhuǎn)換、電壓可調(diào)、大功率、高精度的電源設(shè)計方案。同時設(shè)計了信號采集、傳輸?shù)臏y試電路及可存儲、處理數(shù)據(jù)的軟件平臺,并應(yīng)用于實際的加速試驗中證明該測試系統(tǒng)是可行的。這種應(yīng)用于加速試驗的地鐵車輛小型電器設(shè)備在線測試系統(tǒng)可實時檢測小型電器設(shè)備的吸合時間、接觸電阻等數(shù)據(jù),為小型電器設(shè)備的維修維護提供重要的參考數(shù)據(jù)。

Abstract: In order to meet the requirements of online electrical performance parameter testing for various small electrical components of metro vehicles under the accelerated test, an online test platform for small electrical equipment of metro vehicles based on accelerated test was proposed through the design and improvement of the traditional online test power supply, test equipment and data processing system. According to the special requirements of small electrical equipment for metro vehicles, the design idea of power supply with AC and DC, adjustable voltage, high power and high precision was put forward. The test link of electrical signal acquisition and transmission was designed, and the feasibility of the test link was proved in the actual experiment. An online test system which can process the electrical signal data in real time and calculate and store the electrical performance parameters of small electrical equipment of metro vehicles was constructed.
Key words : metro vehicles;small electrical equipment;evaluating indicator;accelerated test;test platform

引言

地鐵車輛小型電器設(shè)備是關(guān)系車輛運行安全的重要電子器件,對小型電器設(shè)備進行實時狀態(tài)監(jiān)測、準確提出維修維護建議、預(yù)測剩余壽命,不僅可以保證車輛運行安全,還可以降低當前維修維護模式的經(jīng)濟損失[1-4]。

加速試驗是在不改變產(chǎn)品失效機理前提下對產(chǎn)品加載高于正常使用條件的應(yīng)力,加快產(chǎn)品失效或性能退化,通過對加速應(yīng)力下的電性能退化數(shù)據(jù)進行統(tǒng)計分析,預(yù)測產(chǎn)品正常使用壽命指標的一種技術(shù)途徑[5]。對于高可靠的小型電器設(shè)備采用加速試驗可以大大縮短試驗周期,提高試驗效率,節(jié)約試驗經(jīng)費[6]。對各電器設(shè)備進行加速壽命試驗是進行可靠性研究的重要基礎(chǔ),也是獲取小型電器設(shè)備性能狀態(tài)評估指標的重要手段。
