| 中文摘要: |
| 目的 研究波纹管旋压成形过程中的尺寸变化规律。方法 对螺形波纹管旋压成形过程进行了数值模拟和实验研究， 探究了其应变分布规律及各主要尺寸的变化情况。结果 波峰外径、 波距及轴向长度减小， 而波谷外径、 母线长度及波谷处壁厚会相应增加。结论 研究结果可为管坯尺寸选择及制件尺寸的补偿提供依据。 |
| 英文摘要: |
| The work was aimed to study the dimensional change of spiral bellows during the spinning process. Numerical simulations and experimental study were conducted for the spinning process of spiral bellows to find out the law of strain distribution， and the variations of main dimensions. The crest diameter， wavelength， and the axial length were reduced，while the diameter of the trough，the bus length，and the thickness at the trough were increased accordingly. The research results can provide reference for the dimension selection of tube blank， and the dimensional compensation of the workpieces. |
