摘要
建立了用于驱动器激发响应信号分析的AR谱数学模型,并对面板峰窝复合材料结构的脱粘损伤进行了实例分析.结果表明,AR模型谱具有连续光滑易于提取损伤因子等特点,应用于主动监测信号的定量表征是非常有效的.
The AR model used to analyze driving response signal is constructed. By the method, the degummed damage in alveolate composite structures is measured. Experiments on the method show that AR model spectrum has the advantage of heving a continuous smooth curve, by which the damage factor can easily be obtained. It will find applications in the quantitative analysis of active monitoring signals.
