| 摘 要： | 本文对无孔型轧制时轧件展宽进行了实验研究和理论分析,在定量分析歪斜轧件轧制时轧件单侧展宽的基础上,采用刚-塑性材料变分原理对歪斜轧件的轧制变形过程进行了解析,通过曲线拟合将最接近真实速度场的数值解表示成了具体的函数表达式,推导了无孔型轧制时轧件宽展系数的理论计算公式。理论计算的结果与实验结果符合很好。

| Abstract: | Analyzing quantitatively the unilateral spreading of a skew stock duringgrooveless rolling, the rolling deformation process is expressed analytically onthe rigid-plastic variational principle. The numerical solution, expressed as fun-ctional equations, is obtained through curve fitting with a goodness of fit mo-st approximate to the actual velocity field. Theoretical formula of spread ratioof a stock in grooveless rolling is derived and the result is proved in good ag-reement with experiments. |
