为了分析1580轧机主偏心轴轴承在板坯侧压过程中的受载情况及其寿命,利用材料力学中的简支梁理论建立了主偏心轴的受力分析模型,以板坯侧压过程有限元模拟的结果作为模型的边界条件,对主偏心轴轴承进行了较详细地力学分析和寿命计算,结合轴承的动态测试结果,验证了轴承受到周期性冲击力的作用。计算结果表明,主偏心轴轴承的计算寿命为1.5年,与现场使用寿命一致。该轴承可以满足现场的使用要求。

In order to analyze the under loading and service life of main eccentric axis bearing of 1580 mill during side pressing for slab,the force analysis model of main eccentric axis was established using the theory of free beam in material mechanics,based on the conditions of results of the finite element analysis in side pressing process for slab.Force analysis and service life calculation were studied for the bearing in detail.Furthermore,the bearing existing periodicity impact force was validated by the results of test and measurement.The results indicate that the service life of main eccentric axis bearing is 1.5 years,and the calculation value can match with the real service life requirement for the on site working condition.
