| 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。

| Abstract: | 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 reducti... |
