摘　　要：以11辊矫直机为研究对象,研究其理论设计方法。针对矫直机设计过程中难以预估矫直性能的问题,在设计阶段,引入弹塑性有限元法,建立11辊冷矫直机辊子三维有限元模型,对矫直机矫直过程进行数值仿真,获得了矫直过程中矫直力、应力、应变、弹塑比及各辊的压下量和矫直后板材每米不平度的关系,并进行样机压下量和每米不平度的现场测量。通过对比,有限元分析与试验结果一致性良好,验证了分析计算的准确性,为矫直机优化设计提供必要的参考依据。This paper focuses on the design of eleven rollers straightener.An elastic-plastic FEM model is introduced to cope with the difficulty of pre-estimating the performance of straightening during the design process.To obtain straightening force,stress,strain,elastic-plastic ratio,relations between reduction amount of roller and roughness of plate per square meter,a three-dimensional element model is established and straightening process is simulated.In addition,an experiment is conducted to measure the reduction amount of roller and the roughness of plate per square meter.It is shown that the results of numerical simulation are consistent with the experimental results.The developed computing model can provide essential references for the optimization of straightener.
