多方向耦合振动连轧机再生颤振建模及应用
Multidirectional regenerative chatter model of tandem rolling mills and its application
摘要
Abstract
To explore the regenerative chatter mechanism in rolling, a new dynamic rolling process model was established firstly. The new model considers the work roll flattening effect, the rolled piece working hardening effect and the roll gap variation generated in vertical and horizontal direction by the work roll vibration. A single stand vibration model was built by coupling the new dynamic rolling process model with multi direction mill stand model. And then the interaction factors between adjacent rolling mill stands, namely the inter-stand tension variation and strip gauge variation passed onto the next stand after a delay time, were represented in functions. Finally, a new multi direction multi stand regenerative chatter model was built. Based on the models, stabilities of each single stand vibration model and multi stand regenerative chatter model were analyzed using the Routh criterion and the integral criterion respectively. The results prove that the proposed model is correct.关键词
