摘要：

设计了一套增量滚压成形装置，采用三维软件进行建模、装配及简化，并应用有限元软件ANSYS Workbench对装配体进行有限元分析。通过对增量滚压成形装置在滚压过程中的静力学分析，得到应力、应变和变形云图，结合装置的材料性能对该装置的刚度进行分析，分析了装置中因为受力不同而容易产生破坏的位置；并对咬入过程进行疲劳分析，指出装置中容易产生疲劳破坏的薄弱环节。针对分析的薄弱环节进行优化，提出新的设计方案，并对新装置进行静力学分析和疲劳分析，结果表明，新的设计方案能够有效地降低最大等效应力和变形量，而强度和抗变形能力有很大提高，其寿命和安全因子也明显提高。

An incremental rolling equipment was designed, and the modeling, assemble and simplification were conducted by three-dimensional software. Then, the assembly was analyzed by finite element software ANSYS Workbench, and the stress, strain and deformation nephograms were obtained by the static analysis of incremental rolling equipment in the rolling process. Furthermore, the stiffness of equipment was analyzed combining with its material properties, and the locations which are prone to damage in the equipment due to different forces were analyzed. At the same time, the fatigue analysis was performed during the biting process, and the weak locations produced by fatigue damage easily in the equipment were pointed out. Finally, the weakness of equipment was optimized, a new design scheme was proposed, and the static analysis and fatigue analysis of the new equipment were carried out. The results show that the new design scheme can effectively reduce the maximum equivalent stress and deformation amount, and the strength and anti-deformation ability are improved greatly. Thus, the life and safety factor are also improved significantly.
