摘要
基于标量型ARMA模态识别方法和遗传算法,研究了导管架海洋平台的结构损伤诊断方法。针对导管架平台的结构特点,利用模态的方向特点,有效地解决了模态识别误差对损伤诊断的影响。数值算例和物理模型试验表明,该方法的损伤诊断精度较高。
Based on scalar ARMA model and genetic algorithm,the structural damage diagnosis of jacket platform is studied.According to the characteristics of jacket platform,the effects of the errors in mode identification on structural damage diagnosis are properly dealt with.The case study shows that the diagnosis of the method mention above is precise and practicable.
