| 摘 要： | 开发了一种分析三维板带轧制过程轧件与轧辊的耦合变形的计算机模拟系统。它耦合了三维刚塑性有限元法,弹性有限元法和计算辊系变形的影响函数方法。采用该系统成功地对PC轧机(Paircrossedrollingmill)轧制过程进行了分析,得到了轧制压力横向分布,前后张力横向分布,金属横向流动,以及轧后板带的横向板厚分布,包括板凸度和边部减薄大量信息等。

| Abstract: | A simulation technique for three-dimensional coupled deformation of work-pieces with rolls in strip rolling processes is developed. Three-dimensional rigid-plastic finite elements, elastic finite elements and influential function method for the analysis of deformation of rolls system are combined. The system is applied successfully to analyzing the rolling process of PC mill. A wealth of information is obtained about the lateral distribution of rolling load, lateral distribution of front and back tensions, lateral distribution of strip lateral flow, and lateral thickness distribution of rolled strip including strip crown and edge drop. |
