摘要

摘要: 针对45°圆锥台件的单点增量成形过程，分别通过理论解析、实验验证、ABAQUS/Explicit有限元仿真对成形过程中成形力的变化规律进行研究。在验证有限元模型正确的基础上，进一步得到轴向进给和走等高线这两部分的成形力，并对其大小和变化规律进行研究。结果表明，轴向进给时的轴向力明显大于走等高线时的轴向力，因此成形设备和成形工具的设计应充分考虑轴向进给时的轴向力。

Abstract: For forming the cone part with a forming angles of 45°, the theoretical analysis, the experimental investigation and the finite element simulation via ABAQUS/Explicit were respectively used to study the variation of forming force in the forming process. Based on the exactness of the finite element model, the forming forces in the axis direction and contour line direction were obtained, furthermore the magnitude of forming forces and its changing rules have also been studied. The results show that the axial force in the axis direction were much greater than that in the contour line direction, so the design of forming facilities and tool should take full consideration of forming force inn the axis direction.
