为了降低翼子板全工序成形模拟难度,提高翼子板全工序成形模拟精度,减少生产准备阶段设变修模发生率,以某SUV车型翼子板为研究对象,应用CAD软件进行精细化工艺模面设计,并将工艺模面导入CAE软件进行迭代计算,验证翼子板全工序工艺可行性,快速识别了翼子板全工序成形性不良,根据CAE分析结果对CAD模面进行设计优化。研究表明,基于CAD模面的全工序成形分析,大幅削减了翼子板在CAE软件中工序规划、模面设置以及反复调整的工作量,成形评价项目一次分析通过率高,模拟精度显著提升,模具切削后的设变发生率明显下降,实现了翼子板全工序成形模拟的高效化和精准化。

In order to reduce the difficulty of fender complete stamping process simulation,improve the simulation accuracy,and lesson the incidence of design change,a SUV model fender was studied.The detailed dieface was designed in CAD platform,and the detailed die face was simulated in CAE platform.Feasibility of complete stamping process for fender was verified,and the potential forming defect was recognized instantly.According to the result of CAE simulation,the die face of fender was optimized.This study showed that workload difficulty offender complete stamping simulation was decreased dramatically,the first time pass rate of formability was higher than before,and the simulation accuracy was improved significantly.Therefore,the incidence of design change was lessened after die mechanized,and the simulation of complete stamping process for fender was turned to more efficient and accurate.
