ժҪ In order to build high accracy integral dynamic models of cold rolling mill system, by analyzing the vibration process of cold rollilng, the dynamic model of 4-h mill is built, including the rolling process model, the mill roll stand structure model and the hydraulic servo system model. These three models are coupled and linearized, then the multiple input multiple output(MIMO) linear transfer function model of single stand 4-h cold mill system is obtained. The model was carried out with the proposed data to prove its validity, meanwhile the effects to the stability of cold rolling mill system with different working conditions have been discussed. Simulation resulsts show that the model in accord with formers�� models and has its own advancement. It can make contribution to the further study on analysis and supression of coupling vibraiton.
