| 中文摘要: |
| 目的 建立深海压力–流速耦合环境下有机涂层的寿命预测模型，并预测有机涂层在该环境下的服役寿命。方法 首先针对涂层的湿态附着力变化结果，基于灰色系统理论，建立湿态附着力的GM(1,1)模型。随后再基于耦合环境下的试验结果，建立涂层水传输的扩散模型。最后，在此基础上，利用灰色关联分析方法，计算这2种失效影响因素在涂层失效过程中所占的权重因子，并基于这2个影响因素建立涂层失效的数学模型。结果 经过数学统计验证和试验结果对比验证，该模型精度良好，可靠性高。结论 该模型能够对深海压力–流速耦合环境下有机涂层的寿命进行准确预测。 |

| The work aims to establish a life prediction model of organic coatings in the deep-sea pressure-velocity coupling environment, and predict the lifetime of organic coating in this environment. First, a wet adhesion GM (1,1) model was established according to the grey system theory and the results of wet adhesion change of the coating. Then based on the experimental results in this environment, the diffusion model of the coating water transport was established. Finally, the grey relational analysis method was used to calculate the weight factors of the two failure influencing aspects in the coating failure process and establish the mathematical model of coating failure based on these two influencing aspects. After mathematical statistics verification and experimental results comparison verification, the model had good accuracy and high reliability. The model can accurately predict the lifetime of organic coatings in the deep-sea pressure-velocity coupling environment. |
