| 中文摘要: |
| 目的 通过制定系统的整车防腐开发流程和零件防腐要求，并借助SE分析手段，保证车辆的防腐性能满足市场及整车强化腐蚀试验的要求。方法 采用整车强化腐蚀试验验证了不同防腐要求零件的实际防腐性能；通过对车身结构SE分析，阐述了车身防腐性能开发原则及易腐蚀结构。结果 240 h盐雾试验可以满足发动机舱内零件的整车防腐要求，10个周期的循环试验可以满足外饰金属油漆部件的防腐要求。前期的SE分析，可以将腐蚀风险项关闭在设计阶段。结论 对整车防腐性能进行充分的评估，应积累市场腐蚀数据、整车强化腐蚀试验数据和零部件腐蚀试验数据，在数据积累的基础上，建立完善的验证和评价标准体系，从而保证开发车型的防腐性能达到目标要求。 |

| The work aims to ensure that auto corrosion resistance meets market demand and requirements of vehicle intensive corrosion test by developing systematic vehicle anticorrosion development process and requirements for parts anticorrosion. Vehicle accelerated corrosion test was performed to verify actual corrosion resistance of parts subject to different anticorrosion requirement; vehicle anticorrosion development principle and easily corroded structure were also elaborated based on SE analysis. 240 h salt spray test could meet the vehicle requirements for parts anticorrosion in engine compartment, 10 cycles cyclic test could meet anticorrosion requirements for exterior metallic-based parts. The corrosion potential risk could be removed in design stage by SE analysis. In order to evaluate vehicle corrosion resistance, it is essential to accumulate market corrosion data, vehicle accelerated corrosion rest data and components corrosion test data, and then establish consummate verification and evaluation standard system to achieve target anticorrosion requirements for vehicles under development. |
