基于RFK参考车身的整车质量推进优势

Advantages of Whole Vehicle Quality Promotion Based on RFK Reference Body

汽车外覆盖件零件质量的优劣影响着用户决策买车的第一印象。主机厂在汽车外覆盖件的精致性上投入了越来越多的关注。通过引入RFK参考车身搭建方法,通过增加批量阶段RFK搭建轮次来控制外覆盖件尺寸一致性和稳定性。该方法考虑到车身零件电泳和预变形影响,更贴合实际生产装配状态,在局部坐标系下去评价零件匹配状态,展示的抱怨问题与实车装配的抱怨一致性更强,目前RFK搭建在大众体系车型下已经取得了良好的应用效果。

The quality of automotive exterior parts affects the user's first impression when buying a car.Automotive OEMs invest more and more attentions in the refinement of exterior parts.At SAIC Volkswagen,By introducing the RFK reference body construction method and increasing the number of RFK construction rounds in the batch stage,the consistency and stability of the dimensions of the outer covering parts were controlled.This method takes into account the effects of electrophoresis and pre-deformation of car body parts,which is more in line with the actual production and assembly status.It evaluates the matching status of parts in a local coordinate system,and the displayed complaint issues are more consistent with the complaints of actual car assembly.At present,RFK has achieved good application results in Volkswagen system vehicle models.
