摘　　要：介绍了轧辊弹性变形影响函数解析方法的基本理论与公式.采用Fortran语言编写了轧辊弹性变形解析软件.采用编写的解析软件对某1 700 mm热带轧机精轧机组进行模拟计算,计算结果表明:增大弯辊力将降低出口带钢凸度;弯辊力的变化对辊间压力分布、工作辊挠度及辊间压扁的影响较大,而对支撑辊挠度及工作辊与轧件间的压扁影响不大;辊间压力在支撑辊端部位置存在峰值.以上模拟计算结论均符合轧制理论及现场实际.Theory and basic formula of roll elastic deformation on a 4-h mill were investigated with the influence function analysis introduced and the analysis of roll elastic deformation program made for the simulation of an 1 700 mm hot strip mill （HSM） to calculate the roll deformation. The results showed that the increase in roll bending force will decrease the crown of strip at exit, and the change in roll bending force has great influence on the distribution of pressure acted on strip by backup roll and work rolls, work roll deflection and flattening effect due to backup and work rolls, while the influence on backup roll deflection and flattening effect due to strip and work roll is small. There is a peak value of pressure due to both rolls at both ends of the backup roll. All the results mentioned above are in agreement with the theory of rolling process and what happened in the site.
