| 中文摘要: |
| 为了更好地研究缸筒内表面成形质量以及工艺参数的合理性。利用Deform有限元分析软件对液压缸缸筒内孔表面滚压加工状态进行有限元分析，从分析结果中得到缸筒的等效应力、表面受力分布、材料速度矢量以及成形表面质量等，通过缸筒内孔滚压的有限元分析，对液压缸缸筒内孔滚压成形工艺编制提供了一定的指导。 |

| The paper aims to study surface shaping quality and reasonability of technological parameter in cylinder barrel preferably. FEA software was adopted to have finite element analysis on inner hole rolling state of hydraulic cylinder barrel. Equivalent stress, surface stress distribution, velocity vector and forming surface quality, etc. of the cylinder barrel were obtained from analysis. Finite element analysis on inner hole rolling of hydraulic cylinder barrel provide certain guidance for forming inner hole rolling process of hydraulic cylinder barrel. |
