| 摘 要： | 通过有限元数值模拟方法得出滚珠旋压中薄壁管在不同凹模旋转速度条件下轴向进给比的变化规律及工件的成形规律,并对模拟结果的等效应变分布做了分析,并与实验结果进行比较,给出薄壁管滚珠旋压时进给比的选取范围.结果表明,进给比对滚珠旋压中薄壁管直径的胀缩和工件的质量有着显著的影响.另外,从计算的模具所受的三向载荷变化情况分析了模具的使用寿命. |

| Abstract: | Using numerical simulation method of FE,the rule of variation of axial feed rate and the rule of the workpiece forming are obtained under the varions rotational velocity of cavity die for the thin-walled tubes in ball spinning.The distribution of simulated equivallent strain is analysed in comparison with the experiments result.The selection range of the feed rate for the ball spinning of thin-walled tubes is given.The analysis indicates that the influence of the feed rate on the expasion and contraction of the diameter of the thin-walled tubes in ball spinning and the workpiece quality is very evident. |
| Keywords: | axial feed rate ball spinning thin-walled tubes |
