【摘要】 冷弯型钢和焊管是广泛应用的型材,但其成型机理较难描述。针对实际冷弯成型轧制过程,为了更精准地进行应力应变分析,提出了轧制过程的动态链式模型,在样条有限条法的基础上,利用该模型研究实际轧制过程中结点与链的变形分析方法,给出链式结构结点的孔型应力应变数学描述式,并在此基础上给出了结点的智能结构。对每个结点和链建立对应的Agent,建立各Agent的知识规则,实现利用链式模型分析冷弯成型轧制过程的新方法。为建立新的复杂断面孔型设计算法提供理论基础。更多还原

【Abstract】 Cold-formed steel and welded pipe is widely used,but its formation mechanism is difficult to be described.Aiming at the actual cold bending forming rolling process,in order to make more accurate analysis to stress and strain,it mentioned dynamic link model of rolling process,and based on the spline finite method,using the model to study the deformation analysis method of node and link in actual roll forming process,giving the holey stress and strain mathematics description type of link structure node,and on this basis intelligent node structure is given.It set up corresponding Agent for each node or link,established knowledge rules for each Agent,and realized a new method making use of link model to analysis cold bending forming.It provides the theoretical foundation of establishing a new complex profile pass design algorithm.更多还原
