车架设计时，特别在结构设计、材料选择时，必须考虑到防腐问题。以车架为例，研究了防腐设计方法，设计阶段引入完整防腐设计理念，研究制定防腐期限/目标，建立车架表面处理层体系，完成表面处理层工艺设计；依据工艺，进行可维修性、缝隙处理、水分和气体滞留、边缘处理、防电磁屏蔽、防喷漆法拉第效应等涂装工艺结构设计；同时提出“焊接表面缺陷要求、螺栓连接方法、装卸/运输和安装过程保护”等要求；完成防腐验证和制定企业标准。实践证明，按此方法进行产品防腐设计，可以提高车架一次性设计成功率至95%，减少设计更改90%以上，同时减少车架制造运输装配过程中80%的涂装问题，更好地约束和选择、管理车架供运商，保证产品质量。

When design the frame, especially in designing structure and choosing material, corrosion problems must be considered. Based on the frame design for example,this paper researched frame anti-corrosion design method. It introduced integrated anti-corrosion design idea in design stage, researched anti-corrosion period/goals, establish the frame surface treatment layer system, completed the surface treatment layer process design. According to the process,this paper designed coating process structure,such as maintainability, gap, water and gas holdup, edge treatment, anti-electromagnetic screen, anti-painting Faraday Effect, and so on, put forward requirement of “weld surface defects requirements, bolt connection method, loading and unloading/transportation and installation process,and so on”,complete anti-corrosion verification and formulate enterprise standards. The practice proved that using this method to complete product anti-corrosion design can improve the one-time success rate to 95%,reduce design changes by more than 90%,in the meantime, reduce the coating problem to 80%in manufacturing and transport and assembly, better constraint and select, manage frame operators,ensure the quality of products.
