摘 要: 采用剛塑性有限元法,以實(shí)驗(yàn)結(jié)果為依據(jù),以大型有限元軟件ANSYS為分析工具,對雙金屬復(fù)合帶材軋制過程進(jìn)行計(jì)算機(jī)數(shù)值模擬。分析了雙金屬復(fù)合帶材同步或異步軋制過程中,軋輥和軋件的應(yīng)力、應(yīng)變分布和軋件的塑性流動(dòng)變形情況以及軋制力和力矩。以動(dòng)畫的方式模擬軋制過程,給出了一種預(yù)測軋制結(jié)果、減少實(shí)驗(yàn)時(shí)間和費(fèi)用的有效方法。

Abstract: A method to simulate the rolling process of bimetal composite sheets was given. Based on rigid-plastic finite element method,in terms of experiment results, and by the means of FEM software ANSYS,the deformations, stresses,strains,plastic flowing in sheets, rolling forces and rolling moments in symmetrical or asymmetrical rolling of bimetal composite sheets were analyzed. The results above were expressed in computer animated way. An effective approach to predict rolling results and to reduce test time and test cost is provided.
Key words: rolling of bimetal composite sheets; numerical simulation; rigid-plastic finite element method
