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.
