(Summary description)Customized SILICONE STRUCTURAL SEALANT from China manufacturer refers to the adhesive with high strength, can bear large load, aging resistance, fatigue resistance and corrosion resistance, and has stable performance within the expected life. It is suitable for bearing the bonding of strong structural parts. Non structural adhesive has low strength and poor durability. It can only be used for bonding, sealing and fixing of ordinary and temporary properties, and cannot be used for structural adhesive bonding. NEUTRAL SILICONE WETHERPROOF SEALANT from China manufacturer is a structural adhesive with waterproof function. Silicone glue refers to the adhesive based on silicone rubber. According to different functions, it can be divided into structural adhesive, potting adhesive, sealant, thermal conductive adhesive, flame retardant adhesive and so on.

基于以可靠性為中心的維修(RCM)理論，結(jié)合某動(dòng)車所動(dòng)車組運(yùn)行信息，對(duì)CRH380AL型動(dòng)車組車窗MS密封膠故障模式與影響、維修質(zhì)量進(jìn)行分析，識(shí)別維修質(zhì)量異常動(dòng)車組。統(tǒng)計(jì)運(yùn)行滲水故障信息，采用威布爾分布構(gòu)建車窗MS密封膠壽命可靠度模型，計(jì)算動(dòng)車組車窗MS密封膠可靠性壽命模型，優(yōu)化維修周期，提出匹配現(xiàn)有修程修制的質(zhì)量控制建議與優(yōu)化建議。
車窗MS密封膠作為形成動(dòng)車組車體密封性能的主要結(jié)構(gòu)，對(duì)于安全運(yùn)行具有重要意義，動(dòng)車組運(yùn)行過程中發(fā)生車窗滲雨故障，在運(yùn)用檢修期間必須扣車處置，影響正常生產(chǎn)運(yùn)營(yíng)。傳統(tǒng)的車窗MS密封膠為保證車體氣密防水性能，使用計(jì)劃預(yù)防修與故障修結(jié)合的維修方式，按修程開展檢修，當(dāng)前以計(jì)劃預(yù)防修為主、故障修為輔，存在過度維修、維修不足、維修質(zhì)量失控、故障修時(shí)間成本高等問題。因此調(diào)整車窗MS密封膠修程、控制維修質(zhì)量、避免過度維修與維修不足、降低檢修成本從而提高動(dòng)車組可用率成為當(dāng)務(wù)之急。
以可靠性為中心的維修(RCM)分析是在開展裝備故障模式與影響分析的基礎(chǔ)上，對(duì)維修方式的技術(shù)可行性、有效性和經(jīng)濟(jì)性進(jìn)行邏輯決斷，并計(jì)算各種維修方式的維修間隔期，進(jìn)而確定科學(xué)合理的修程修制。對(duì)比了RCM理論與傳統(tǒng)維修策略，并通過介紹輪對(duì)維修的RCM分析體現(xiàn)了RCM理論在降低輪對(duì)故障風(fēng)險(xiǎn)方面的優(yōu)勢(shì);將RCM理論應(yīng)用于動(dòng)車組全自動(dòng)車鉤的修程分析，運(yùn)用威布爾分布建立了全自動(dòng)車鉤各部件的可靠性壽命模型。但以上分析均未考慮維修質(zhì)量對(duì)壽命參數(shù)的影響。
本文基于RCM理論，選取CRH380AL型動(dòng)車組車窗MS密封膠滲水故障開展實(shí)例分析，進(jìn)行維修質(zhì)量分析，識(shí)別維修質(zhì)量異常，確定車窗MS密封膠維修質(zhì)量控制要點(diǎn)，建立可靠性壽命模型，計(jì)算車窗MS密封膠可靠性壽命，對(duì)車窗MS密封膠維修質(zhì)量控制與修程修制提出相關(guān)優(yōu)化建議。http://www.cs535.com/
