摘　　要：VC轧辊由芯轴和辊套装配而成,在辊套和芯轴之间有一油腔,辊套在芯轴两端过盈装配,能承受轧辊扭矩,并同时能将高压油密封在油腔中。液压胀形轧辊本身的结构参数对于该技术能否成功具有举足轻重的地位。使用有限元法模拟了液压胀形轧辊的过盈装配,讨论了辊套壁厚、过盈量大小以及过盈配合长度等结构参数对VC轧辊静载凸度的影响,为VC轧辊的设计提供参考依据。VC roller is consisting of a mandrel and a roller sleeve, with an oil chamber between them. The interference fitting of roller sleeve on the two sides of mandrel allows the sleeve to endure a roller torque, and meanwhile, the oil can be pressurized in the oil chamber. The construction parameters of the hydraulic elastic bulging roller itself play an important part on whether the technique is successful or not, The use of finite element simulated the interference fitting of hydraulic elastic bulging roller, as well as discussed the influence of the construction parameters, such as the sleeve thickness, the amount of interference, and the length of interference match, on VC dead load crown, which offers reference for the design of VC roller.
