为提高预弯成形质量，采用有限元法分析了预弯成形过程，并验证了计算结果的准确性。在此基础上，考虑板料的材料性能参数等不确定因素对成形质量的影响，并基于随机模型的稳健性设计方法获得了预弯成形技术参数的稳健性优化设计方案。研究结果表明：稳健性优化使成形质量的性能指标得到了改善，将可靠性由4.2%提高到97.7%，显著提高了焊管成形质量可靠性。

To improve crimping forming quality,this paper investigated crimping which was simu-lated using the FE code ABAQUS and the FE model was validated experimentally.Based on this anal-ysis,robustness design method based on stochastic model was used to obtain optimization design scheme,which considered the effects of uncertain factors such as material performance parameters on the forming quality.The research results show that the optimization design scheme can improve the product performance,and increase the reliability from 4.2% to 97.7% and ensure the product quality. Thus,the results herein provide an effective approach for crimping parameter design.
