碳纤维增强塑料（CFRP）层合结构的损伤评估对于保证结构在使用中的安全性非常重要。机器学习是CFRP结构损伤评估的研究热点。但存在噪声干扰、训练样本数量少、训练样本损伤类型少等问题。为了解决上述问题，提出了基于同步压缩小波变换和系综主成分分析的CFRP层合板损伤评估方法。首先，提出了基于同步压缩小波变换（SWT）和奇异谱分析（SSA）的损伤特征提取方法，以降低特征维数，实现损伤特征的有效提取。然后，提出基于集合主成分分析(PCA)的损伤评估方法，实现CFRP结构的损伤评估。最后设计仿真实验，验证噪声干扰、训练样本数量较少、训练样本损伤类型较少情况下的损伤评估结果。结果表明，基于SWT、SSA和整体PCA的CFRP层合结构损伤评估方法是可行的。为评价CFRP层合结构损伤程度提供了一种可行的方法。
The damage assessment of Carbon Fiber Reinforced Plastics (CFRP) laminate structure is very important to ensure the safety of the structure in service. Machine learning is a research hotspot in damage assessment of CFRP structures. However, there are problems such as noise interference, small number of training samples, and few damage types of training samples. In order to solve the above problems, the damage assessment method of CFRP laminate based on Synchrosqueezed Wavelet Transform and ensemble Principal Component Analysis was proposed. First, the damage feature extraction method based on Synchrosqueezed Wavelet Transform (SWT) and Singular Spectrum Analysis (SSA) was proposed to reduce the feature dimension and achieve effective extraction of damage features. Then, the damage assessment method based on ensemble Principal Component Analysis (PCA) was proposed to realize the damage assessment of CFRP structure. Finally, the simulation experiment was designed to verify the damage assessment results in the case of noise interference, small number of training samples, and few damage types of training samples. The results showed that the damage assessment method of CFRP laminate structure based on SWT, SSA and ensemble PCA was feasible. This paper provided a feasible method for evaluating the damage degree of CFRP laminate structure.
