Research on intelligent precise pass design algorithm

Abstract

Along with the functional requirements of coldformed steel are more and more high in engineering field,the cross-section geometry shapes become more complex, and the pass design of rolling steel is more difficult. The design method relied on experience and estimation can not meet the requirements of engineering .How to make the system of pass design algorithm stable become the difficulties in the pass design of model steel. Although the researches on cold roll forming theory are more, less theory is used as a guide for pass design. In this paper, a new model of rolling process based on the spline finite strip theory is studied and established, which constructs the Agent structure by using a chain store mode for the shaping of each pass and the deformation of transition zone. The model can realize the stress and strain description of intelligent single-pass roll forming and establish the parameters links between the forming theory and pass design to provide a theoretical basis to deduce accurate pass design.
