某车型车身A柱电泳结构的优化

Optimization of A-shaped Column Electrophoretic Structure of the Car Body

简要介绍了涂装同步工程在新车型开发各阶段的主要工作内容,详细论述了车身空腔钣金之间的间隙、孔径、孔距及对穿孔等对空腔电泳性的影响。针对某车型工程样车E D车身拆解暴露的A柱空腔局部电泳膜厚偏薄的问题,根据各钣金件的结构特点、搭接方式及钣金间形成的空腔大小等,对其结构进行了优化,并应用ECoatMaster对优化后的车身数据进行仿真计算和ED车身的拆车验证,提升了车身的电泳涂层质量,满足整车防腐的设计要求。

Based on painting simultaneous engineering method, the main painting related work in the stages of new car model development was briefly introduced. Parameters influencing the quality of cavity electrophoresis such as gap between the body cavity sheet metal, pore diameter, distances between the hole, as well as facing perforated are analyzed. Focus on the problem of local electrophoresis film thin in A- shaped column by ED body dismantling engineer prototype, the car body data model has been established and analyzed by ECoatMaster. The structural features of sheet metal parts, overlap mathord, cavity size were optimized and verified. The quality of cavity electrophoresis was promoted and satisfied the design requirements of vehicle corrosion protection.
