| 摘 要： | 针对结构损伤识别中,损伤与其影响因素之间的复杂非线性关系,提出了结构损伤识别的支持向量机方法。支持向量机是一种基于统计学理论的机器学习算法,本文以模态频率作为损伤标识量,通过支持向量机建立了损伤程度和频率之间的支持向量机模型,并以悬臂梁的损伤为例进行了计算分析,结果表明提出的方法是科学,可行的。 |
| 关 键 词： | 损伤识别 支持向量机 核函数 模态频率 |

| Abstract: | In allusion to the complex nonlinear relationship between the damage and influencing factors with regard to structural damage detection was proposed damage identification of support vector machines.SVM is a machine learning algorithms based on the statistical theory,we used the modal frequency as the amount of damage in this paper,established the svm-model between the degree of injury and the modal frequency through support vector machine and calculated by an scathing example of cantilever beam.The result s... |
