摘要：

针对13×4.50B车轮轮辋的结构特点，利用有限元软件ABAQUS/Explicit对车轮轮辋辊压成形工艺及关键工艺参数进行数值分析，并进行试验验证。模拟分析了轮辋辊压工艺中的辊压成形次数n、变形系数M、轮辋标定直径D和轮辋标定宽度A等参数对辊压成形的影响；介绍了车轮轮辋关键尺寸的计算方法；通过模拟分析得到了轮辋的扩口应力和厚度关系云图、第一至第三辊压应力和厚度云图，并进行辊压过程准静态分析等。模拟结果表明：变形系数M为关键工艺参数，标定宽度尺寸A和轮辋标定直径D在各道次中基本保持一致，D的扩张余量为1%较合理，试验结果与模拟结果相符合。

Based on the structural feature of wheel rim 13×4.50B, the wheel rim roll forming process and the key parameters were numerically analyzed by finite element software ABAQUS/Explicit, and all tests were verified. The influences of the rolling times n, deformation coefficient M, the rim diameter calibration D and the rim width calibration A etc. on roll forming were simulated. The calculation method of the critical dimensions of the wheel rim was introduced, the distribution of rim flaring stress and thickness, the first to the third roller pressure and thickness were obtained by simulation analysis, and quasistatic analysis of rolling process was carried out. The simulation results show that the deformation coefficient M is the key process parameter, the rim width calibration A and the rim diameter calibration D are almost consistent in each time, and the expansion allowance D of 1% is more reasonable. The experimental results coincide with the simulation results.
