1、北京交通大學(xué)碩士學(xué)位論文鐵路鋼軌傷損管理研究姓名:劉婷婷申請(qǐng)學(xué)位級(jí)別:碩士專業(yè):交通運(yùn)輸規(guī)劃與管理指導(dǎo)教師:王福田20090601中文摘要鋼軌是鐵路軌道設(shè)備的重要組成部分,它直接承受列車運(yùn)行過程中產(chǎn)生的動(dòng)載荷,鐵路鋼軌傷損的日常管理工作是保證鐵路線路安全、平穩(wěn)和不間斷運(yùn)營的重要手段。本文通過分析國內(nèi)外鋼軌傷損管理的現(xiàn)狀,對(duì)鋼軌傷損管理相關(guān)數(shù)據(jù)進(jìn)行規(guī)范和整合,并在此基礎(chǔ)上對(duì)鋼軌傷損的“狀態(tài)修”閉環(huán)管理方式進(jìn)行了深入研究。鋼軌傷損“狀態(tài)修"閉環(huán)管理強(qiáng)調(diào)對(duì)鋼軌狀態(tài)的把握,要求能夠通過對(duì)鋼軌狀態(tài)的變化趨勢(shì)進(jìn)行分
2、析預(yù)測,鋼軌傷損管理相關(guān)數(shù)據(jù)是實(shí)現(xiàn)鋼軌傷損“狀態(tài)修"閉環(huán)管理的基礎(chǔ)和關(guān)鍵。論文對(duì)鋼軌傷損相關(guān)數(shù)據(jù)分類和來源進(jìn)行了詳細(xì)的描述和分析,并按照“狀態(tài)修”的要求對(duì)鋼軌傷損數(shù)據(jù)進(jìn)行了規(guī)范和整合,為研究鋼軌傷損“狀態(tài)修’’管理提供了準(zhǔn)確規(guī)范的數(shù)據(jù)基礎(chǔ)。在規(guī)范整合鋼軌傷損相關(guān)數(shù)據(jù)的基礎(chǔ)上,需要對(duì)數(shù)據(jù)進(jìn)行充分合理的利用才能保證鋼軌傷損“狀態(tài)修"管理的實(shí)現(xiàn)。論文對(duì)鋼軌傷損相關(guān)數(shù)據(jù)的運(yùn)用進(jìn)行了深入分析,針對(duì)不同管理層級(jí)對(duì)數(shù)據(jù)進(jìn)行了微觀和宏觀的分級(jí)運(yùn)用管理,在分析鋼軌生命周期一般規(guī)律的基礎(chǔ)上,對(duì)“狀態(tài)修"思想指導(dǎo)下的鋼軌傷損
3、閉環(huán)管理進(jìn)行了研究,并在積累鋼軌傷損數(shù)據(jù)的基礎(chǔ)上對(duì)鋼軌疲勞周期預(yù)測進(jìn)行了初步研究。論文將研究成果運(yùn)用于昆明局鋼軌傷損管理信息系統(tǒng),該系統(tǒng)是昆明鐵路局工務(wù)安全生產(chǎn)管理信息系統(tǒng)中的一個(gè)子模塊,目前在昆明鐵路局運(yùn)行良好,論文對(duì)該系統(tǒng)的實(shí)施情況進(jìn)行了介紹。關(guān)鍵詞:鋼軌傷損;數(shù)據(jù)規(guī)范;狀態(tài)修;閉環(huán)管理;鋼軌疲勞分類號(hào):U216.3ABSTRACTRailis趾importantcomponentofrail、Ⅳaytrackfacilities,whichsustainsthedynamicloadoftrain
