The Deforming Route of Buckled Waves of Rolled Strip
-
摘要: 通過建立冷軋帶材屈曲失穩后的大位移變形模型,計算出復雜模態的瓢曲浪形生成路徑,它包含著實際可能出現的各種附加應力和位移約束條件.實驗證明這是可行的板形控制目標理論,解決了高技術軋機的板形設定問題.Abstract: The stability of rolled strip is the shape criterion or predicting problem to be solved in the shape control system.The thesis established a postbuckling model to study the deformation of cold rolled strip.The deforming route of complex buckled waves involved in all kinds of appending stresses and restricted displacements was calculated.An experiment proved it was the theory for target shape setting on the "high-tech" rolling mill.
