fatigue break 中文意思是什麼
fatigue break
解釋
疲勞斷裂-
Based on the previous research on the portal crane administration, one standpoint put forward in this paper is idea that is on the foundation of reliability in this paper, two viewpoints take shape when reason is analyzed, that is fatigue break and appearing the flaw that will extend. what is the fatigue break ? ( this phenomenon is always happen in some place ), the fatigue is that board appears apophysis and concave when the board is pressed. so that the board ability of bearing the weight of load will descend
本論文建立在已有的港口裝卸機械管理的研究基礎之上，進一步提出了以可靠性為基礎的港口裝卸機械的管理思想，已有的研究表明，港口機械設備破壞主要由於兩個原因，第一是穩定性問題，特別是構件的局部穩定性，所謂穩定性是指：在板的平面內，板受到平行於板面的壓力作用，使板發生隆起、內陷等凹凸不平的結果，從而使板受載能力減弱；第二是結構出現疲勞裂紋及其擴展，這是由於設備長時期運行，而造成設備某些部位出現裂紋並得以擴展，使設備承載能力下降。 -
The fatigue fracture occurred in the root of the screw where defects such as decarburization and cracks existed, and these defects made the zone to be a stress concentration area and caused the bolts to break finally
疲勞裂紋的形成是由於螺紋牙底存在脫碳和折疊裂紋等缺陷，這些缺陷的存在使該材料產生了較大的應力集中，從而導致螺栓開裂失效。 -
At the same time, the fatigue behavior of the liner has also been improved due to the reduction of the stress concentration and micro - break on the inner surface
內表面採用特殊工藝處理，物理機械性能明顯改善，消除了表面應力集中及微觀裂紋，鋁膽的疲勞性能得到提高。
