How to build a stable pipe roller design algorithm system has become the difficulty of modern steel pipe roller design. Although the theory researching cold bending forming is more now, but the theory used to guide pass design is less. This paper studied and established the new rolling process model based on spline finite strip theory. It’s good to Shape the way time and build the chain storeing deformation way Agent structure in transition region. It helped to realize intelligent single channel cold bending forming a stress and strain description. And it is usefull to establish forming theory and the parameters contact of the pass design. In a word, it provided the theory basis for the precise pass design.
In cold rolled section manufacture process,the deformation mechanism of steel strip is very complicated,so how to accurately design pass becomes the key link for manufacture.The pass design method originated from deformation theory research,at present,the great difference exists between theoretical study and pass design method,namely the current theory method can not accurately guide pass design.To add artificial intelligence method can greatly improve the above problems.Combing the characteristic finite spline method with characteristic Agent method to dispose intelligently deformation theory,on this basis,select finite spline and Agent,establish system of characteristic finite spline and characteristic Agent,and using them to product deformation analysis,the more accurate relationship between steel strip displacement and energy can be obtained,thereby the method of accurate design pass can be achieved.
We prove that groups acting geometrically on delta-quasiconvex spaces contain no essential Baumslag-Solitar quotients as subgroups. This implies that they are translation discrete, meaning that the translation numbers of their nontorsion elements are bounded away from zero.
