輥軋成形法 的英文怎麼說
中文拼音 [gǔnyàchéngxíngfǎ]
輥軋成形法
英文
roll forming-
The high speed steel of composite roll is characteristic of high carbon and high alloy elements. so it is easy to form a lot of netlike carbides. these carbides which are very hard and fragile and are very difficult to be eliminated by heat treatment can depress the properties of high speed steel
復合軋輥用高速鋼具有高碳和高合金的特徵，容易形成大量網狀碳化物，這些網狀碳化物又硬又脆，會嚴重降低高速鋼的性能，且難以用熱處理的方法予以消除。And relying on this, our laboratory proposes a new cladding method. by means of large dynamic explicit fem code ansys / ls - dyna, the numerical simulation was carried out in bimetal forming process. during the simulation of the forming process, the large deformation of the strip should be considered, as well as geometrical and material nonlinear, the contact between the roller and the strip, the contact between two metal sheets and the load. as for these problems, we can use node to surface contact and relative parameters, biso model is introduced, the load is applied as array
本文採用ansys / ls - dyna計算程序為分析工具，對鋸齒形雙金屬復合板成型過程進行計算機數值模擬，在對軋制過程模擬時，針對軋件變形的幾何非線性和材料非線性特點、軋輥與軋件間的接觸、軋件間的接觸以及模型的加載等問題，給出了在ansys / ls - dyna中相應的解決方法：應用nodetosurface接觸方式，設定相應參數，選用雙線性等向硬化模型，載荷作為array施加在剛體質心。A 2 dimensional varying thickness finite element model of roll system deformation was built to simulate and analyse rolling process, and then a vcr ( varying contact backup roll ) was designed for the rolling conditions of pl - tcm ( pickling line combined with tandem cold rolling mill ) and has been app - lied to 1700 tandem cold rolling mill at wisco after industrial test
採用二維變厚度有限元方法建立輥系彈性變形模擬模型，研製了酸軋聯機條件下的vcr變接觸支承輥，經過工業軋機現場軋制已成功投入1700冷連軋機實際應用。
