步進焊縫
英文
step-by-step welding-
Recently, train is running faster and faster, and considering the stability and security, seamless welded rails ( swr ) are used as the train orbits gradually. the temperature of the rails will vary with weather. so that the rails may release the energy due to the metal characteristic of expanding or contracting with temperature, there is some badly distortion in the swr, worsly occurring accidents on expanding orbits. the portrait thermal stress ( pts ) of the swr should be monitored in some parts regularly, as to avoid such accident
近年來，隨著火車的提速造成的穩定和安全問題，軌道逐步轉為採用無縫焊接鋼軌，隨著鋼軌溫度的變化，無縫鋼軌可能會因為熱脹或冷縮的金屬特性並且在扣件阻力小而且路基較差的路段釋放能量，可能會發生鋼軌嚴重變形，更甚者會發生脹軌跑道等嚴重鐵道事故，為了避免發生如此事故，有必要定期對鋼軌的溫度應力進行檢測。A fuzzy control system of stepping motor for seam tracking is presented in this paper, the proposed system can realize the self - modify ing of the parameters and improve the characteristics of dynamic and static state of stepping driving system according to the error of seam tracking. the accuracy of seam tracking is enhanced obvi ously
介紹一種用於焊縫跟蹤的步進電機模糊控制系統，該系統可根據跟蹤偏差進行參數自調整，改善了步進驅動系統的動靜態特性，提高了焊縫跟蹤精度。It is proved by the intensity experiment of welding line that the welds of these two materials using explosive welding and vacuum electron beam self - material brazing are tolerable, nevertheless the welding technique could be improved basing on the study of microstructure of the joint layer
通過強度實驗的研究，兩種工藝形成的焊縫強度都是可以滿足目前的應用要求的，但是，對電子束自釬焊可根據顯微研究的結果做進一步的工藝參數的改進。However, a further investigation is still needed in order to interpret the test results of cross - weld specimens for application in practical welded components
但是試驗室的焊縫試樣能否真實地反映焊接構件的力學行為，則仍是需要進一步研究的問題。The geometrical relation of elliptic imaging is studied for welding seam image of the butt welds in straight tubes. the region model of welding seam image is proposed, it furnishes a evidence theory to further process to welding seam image
哈爾濱工程大學博士學位論文一針對具體的鋼管直管對接焊縫圖象，研究了其橢圓成象的幾何關系，提出了焊縫圖象區域模型，為進一步處理焊縫圖象提供了理論依據。An additional experiment is performed, and the weld specimens and heat effected zone specimens of dh36 steel are researched, through which the outcomes from the formulas of the standard and from other formulas is compared, which demonstrates the validity of standard test means for ctod and j - integral
另外還進行了一個附加試驗，對具有不同尺寸的dh36鋼的焊縫試樣和熱影響區試樣進行了研究，將本文所用標準中公式的計算結果與其它經驗公式的計算結果進行了對比，進一步證明了ctod和j積分標準試驗方法的有效性。分享友人
