石墨密封组件波形弹簧回弹仿真性能分析OA

In this paper,the dynamic explicit calculation simulation method of Abaqus is used to study the forming and unloading rebound of GH738 waveform spring.It is found that if the total design height of the wave spring is 8 mm and the wavenumber N is 3,the rebound of the hydraulic die based on the original height is 2.165 mm.After unloading,the rebound of the peak-valley transition section is larger than that of the wave peak,while the peak and trough still keep part of the bend after rebound,which is due to the smaller plastic deformation area of the transition section.In addition,the rebound of the wave spring is closely related to the thickness of the sheet metal,and with the increase of the thickness,it shows a larger amount of rebound in the forming process,which is due to the increase of the cross-section thickness,which leads to the increase of the rebound in the unloading process.
