摘　　要：建立了森基米尔轧机轧辊与轴承系统相互作用的接触与变形分析模型,采用有限元法对其进行了求解;研究分析了给定轧制工况条件下单、双辊支撑的森基米尔轧机轴承系统的接触载荷、接触应力及变形分布情况;并进一步分析了不同轧制工况条件下单辊支撑时轴承系统的接触行为变化规律。结果表明,在同等轧制工况条件下,与双辊支撑相比,单辊支撑时轴承承受更大的内部接触应力及外圈接触变形;随着轧制力的增大,单辊支撑时轴承内部应力及外圈接触变形增大较为明显。A contact and deformation analysis model is built for roll and bearing system of Sendzimir rolling mill, the solution is given by using finite element method. The contact load, contact stress and deformation distributions of Send- zimir rolling mill bearing system are analyzed and researched when the working roll is supported by one roll or two rolls under the given rolling conditions. The change rules are studied for contact behaviors of bearing system when supported by one roll under the different rolling conditions. The results show that compared to the case supported by two rolls, the bearing is subjected to higher internal contact stress and contact deformation when supported by one roll under the given rolling conditions. The internal stress and contact deformation of the bearing are significantly increased with the increase of rolling force when supported by one roll.
