【摘要】 利用显示动力学有限元分析方法,模拟了波纹轨腰钢轨的轧制过程;分析了轧制速度、压下量、轧件初始厚度对轧制力的影响。在燕山大学三机架万能轧机上进行了波纹轨腰钢轨的轧制实验,在相同的轧制条件下,实验所得的轧制力与数值模拟所得的轧制力基本相符,证明了理论分析的正确性。说明用数值模拟所得的轧制力能参数能够用于指导实际生产中工艺参数的制定。更多还原

【Abstract】 The rolling process of corrugated waist rail is simulated by explicit dynamic FEM.The influence of rolling velocity,reduction and the initial thickness on the rolling force is analyzed.The rolling corrugated waist rail is experimented on the three-stands universal mill of Yanshan University.At the same rolling condition,the rolling force result obtained by experiment is coincident with the simulation,this proves the theory analysis is correct.Therefore,the rolling parameters obtained by simulation can be instructive to the actual production.更多还原
