x100直縫埋弧焊管焊接殘余應(yīng)力測(cè)試分析

1、西安石油大學(xué)本科畢業(yè)設(shè)計(jì)（論文）IX100直縫埋弧焊管焊接殘余應(yīng)力測(cè)試分析直縫埋弧焊管焊接殘余應(yīng)力測(cè)試分析摘要：要：X100直縫埋弧焊管屬于管道鋼的新技術(shù)產(chǎn)品，通過(guò)研究其殘余應(yīng)力，從而可以提高其使用效率及壽命，使管道建設(shè)降低成本和損失，獲得更好的經(jīng)濟(jì)效益。文中采用了盲孔法進(jìn)行對(duì)X100直縫埋弧焊管焊接殘余應(yīng)力的測(cè)試分析，通過(guò)對(duì)實(shí)驗(yàn)數(shù)據(jù)及其平面圖形的分析，從而了解其焊縫接頭周?chē)妮S向殘余應(yīng)力和周向殘余應(yīng)力的數(shù)值及分布情況，判斷其分布規(guī)律。

2、通過(guò)實(shí)驗(yàn)分析，得知X100直縫埋弧焊管的內(nèi)表面及其外表面的焊縫接頭周?chē)妮S向殘余應(yīng)力和周向殘余應(yīng)力的峰值，并通過(guò)分析得出其分布曲線，明了其分布規(guī)律。關(guān)鍵詞：關(guān)鍵詞：殘余應(yīng)力；盲孔法；軸向；周向西安石油大學(xué)本科畢業(yè)設(shè)計(jì)（論文）III目錄1緒論....................................................................................................
