extrusion stress

The intention of this paper is to develop a set of testing system , which has high efficient and reliable performance and advanced technology . it is applied in testing extrusion pressing of new type elevator wire rope tie - in in its making process and tensile strength , fatigue strength of tie - in . then to test the validity of design theory of the new type tie - in by analyzing the testing data and grope for new theory on and on 本課題研究的目的是開發一套高效可靠、技術先進的測試系統,用于測試新型電梯鋼絲繩繩頭制作過程中的擠壓力、以及繩頭本身的抗拉強度和疲勞強度性能,然后根據測試數據來驗證新型繩頭設計理論的正確性,并不斷進行新理論的探索。

The studying results show that three types of surrounding rockmass pressure were put out , they are tension collapse , extrusion press slide types and gravity fall surrounding rockmass pressure , and then calculating formula have been discussed 研究認為,低地應力區地下洞室圍巖壓力可分為拱頂橫向拉張塌落型、側壁切向擠壓滑落型和洞周自重掉落石塊型三種破壞類型產生的圍巖壓力,并討論了低地應力區地下洞室圍巖壓力的計算公式。

The conclusion is that the extrusion presses between primary and secondary linings , elasticity of the waterproof layer and unblocked drainage layer are the vital factors influencing the waterproof layer of spraying - on acrylate membrane in tunnel composite linings 試驗結果表明,襯砌間的擠壓應力、防水層的彈性恢復能力、通暢的排水層對丙烯酸鹽噴膜防水層在隧道復合式襯砌中的防水效能發揮重要作用。

Abstract : genetic algorithm has been used in optimal design of struct ural parameters of elbow bar - type extrusion press to improve smoothness of slid e speed and processing accuracy as well as service life of equipment and dies 文摘:采用遺傳算法對拉力肘桿式擠壓機結構參數進行了優化設計,以提高滑塊工作速度的平穩性、增加擠壓機的加工精度以及設備和模具的使用壽命。

Abstract : this paper introduces the process requirement and the basictechnology with quench . it shows an example of quench used in 100mn a1 extrusion press and the result of the cooling 文摘:介紹了鋁型材擠壓機輸出系統淬火裝置的基本要求、基本技術,簡述了100mn鋁擠壓機淬火裝置及同類產品的冷卻效果。

Recently , several ten sets of crane , leveller , extrusion press , excavator about 3000t mechanical equipments have been exported to the world - wide more than 20 countries 近年來,已經有數十臺起重機、矯正機、擠壓機、挖掘機,約3000多噸機械設備出口到世界20多個國家。

At the meantime , surrounding rockmass pressure of tension collapse and extrusion press slide types have been calculated , by one diversion excavation engineering is taken as an example 以研究區引水洞為例,分別計算了拱頂圍巖整體滑落和側壁圍巖整體滑落型圍巖壓力。
