| 为了进一步研究当量加速关系,归纳了现有腐蚀损伤当量化的研究方法,详细介绍了基于电化学原理、物理参量和力学损伤的当量折算法,讨论了各种方法的优劣和所适用范围。 基于电化学原理的当量加速关系研究方法适合用于制定飞机金属结构加速试验环境谱,以物理参量为基准的当量折算法适用于建立疲劳关键部位、腐蚀关键部位的涂层及金属基体等各种加速试验环境谱的当量加速关系,力学损伤对比法适合用于结构疲劳关键部位。 最后得出针对不同材料、不同部位应该采用不同的当量加速关系的结论。 |

| In order to further study the equivalent accelerated relationship, this paper summarized the existing research on corrosion damage equivalent methods, described the equivalent conversion methods in detail based on the electrochemical principle, physical parameters and mechanical damage, and discussed the advantages and disadvantages of the various methods. The equivalent accelerated relationship research method based on electrochemical principle is suitable for developing the accelerated test environmental spectrum for the metal structure of aircraft, the equivalent accelerated relationship research method based on physical parameters is suitable for establishing equivalent accelerated relationship of accelerated test environmental spectra for the fatigue key sites, the coating of the corrosion key sites and the metal matrix, while the mechanical damage comparison method is suitable for the key sites of structural fatigue. Finally the conclusion was drawn that different equivalent accelerated relationship should be adopted for different materials and different sites. |
