摘要
根据轧辊的约束情况,建立了简化后的有限元模型,分别计算了3种不同轧制工况下轧制点处的应力,得到轧辊的最小安全系数。分析得到距辊身约39mm处的过渡区最易发生疲劳断裂,对现场生产和今后的设计具有指导意义。
Based on boundary constraint of the roller, the simplified finite element model is established. The stress at rolling point is calculated in three working conditions. The minimum safety factor of the roller is obtained. The analysis shows the fatigue fracture may take place in about 39mm transitional zone from the roller. The result has practically guiding meaning to site production and future design.
