A theoretical model for shape control characteristics of DSR skin mill was established and a deformation model of DSR skin rolls system was established through analytical method. The model was calculated based on influence function method, combining the particular principle of DSR roll and the distribution of the hollow roller and the special structure of briquette. On this basis, combining the specificity of skin rolling,a metal deformation model was established. With coupling of the two theoretical models, the whole shape analysis model was established. Then the model of computing processes and procedures were prepared for the research of shape control about DSR skin mill.

建立了动态板形辊(DSR)平整机板形控制特性分析的理论模型。综合考虑了DSR技术独特的板形控制机理,以及其空心辊套和分段压块的特殊结构,基于分割模型的影响函数法,建立了DSR平整机辊系变形的理论模型;在此基础上,考虑平整轧制的特殊要求,将针对平整过程的金属模型和辊系模型进行耦合计算,建立了板形控制分析的整体模型,并编写了模型的计算流程和程序,以此对DSR平整机的板形控制能力进行研究。
