讨论了小波及其特性， 针对目前变形分析模型不足， 建立了基于小波分析的变形分析实用模型， 该模型对变形进行滤波， 从而可揭示变形规律； 提出了基于小波局部特征分析模型， 通过取不同参数， 该模型既适用于分析变形过程整体特征， 还适用于分析动态变形， 而且对多种不同周期变形可进行有效分离。
The wavelet and its characteristics are discussed. According to the deficiency of the current deformation analysis model, a practical model of deformation analysis based on wavelet analysis is established. The model is used to filter the deformation so that the deformation law can be revealed. The wavelet local feature analysis model is proposed to adopt different methods. Parameters, This model is not only suitable for analyzing the overall characteristics of the deformation process, but also for analyzing the dynamic deformation, and it can effectively separate a variety of different cycle deformations.
