- 摘要:
- 基于有限元ABAQUS软件平台对单片闭式波形弹簧进行了弯曲回弹数值仿真模拟与分析，研究了单片闭式波形弹簧母材厚度与冲压力和圆角处的回弹量与摩擦系数之间的关系，得出了冲压模具设计规范和波形弹簧加工工艺规范，采用该工艺规范制造的单片闭式波形弹簧已经用于无人机发动机之中，该发动机已通过地面试车考核，由此表明：单片闭式波形弹簧加工工艺是合理、正确和有效的。
- Abstract:
- Based on the finite element ABAQUS software platform, the numerical simulation and analysis of the single-piece closed wave-shape spring are carried out. The relationship among thickness of spring material, punching force, friction coefficient and springback value at circular angle are studied. The design specifications of stamping die and processing technic specifications of wave-shape spring were obtained. The single-piece closed wave-shape spring manufactured with these specifications has been used in a kind of UAV engine. The engine has been passed the ground test. This shows that the processing technology of the single-piece closed wave-shape spring is reasonable, correct and effective.
