摘　　要：波纹轨腰钢轨是一种特殊的钢轨结构。轧制波纹轨腰钢轨的水平辊由于其外形接近于直齿齿轮而被称为齿型辊。齿型辊的辊型曲线对波纹轨腰的轧制成品质量、成形过程及轧制力均有较大的影响。设计了轧制波纹轨腰的齿型辊辊型曲线,建立了波纹轨腰钢轨轧制的有限元模型,利用ANSYS/LS-DYNA软件模拟了波纹轨腰钢轨的轧制过程。在相同压下量和轧制速度条件下,比较了波纹轨腰钢轨轧制时,实验用辊型曲线和设计辊型曲线轧制力的大小。根据分析结果,设计辊型曲线的轧制力明显小于实验辊型曲线的轧制力。因此,优化辊型曲线从而减小轧制力是必要的。The corrugated web rail is a special kind of rail structure. The horizontal roller of rolling the corrugated web rail is named as tooth-shaped roller because its shape is close to straight tooth gear. The profile curve of tooth-shaped roller has great influence on the finish product quality, the rolling process and the rolling force of the corrugated web. The profile curve of tooth-shaped roller of rolling corrugated web rail was designed. FE model of rolling corrugated web rail was established. And the rolling process was simulated by the software ANSYS/LS-DYNA. Under the conditions of the same reduction and the same rolling speed, the rolling forces between experiment profile curve and the designed profile curve were compared in rolling corrugated web rail. According to the analysis results, the rolling force of the designed profile curve is significantly smaller than that of experimental profile curve. Therefore, it is necessary to optimize profile curve of the tooth-shaped roller to decrease the rolling force.
