1利用加速度响应连续小波变换的时变系统物理参数识别显示文摘基于小波理论,推导了函数积分运算的连续小波变换计算方法,应用此方法仅用线性时变结构的振动加速度响应信号,就可计算出速度和位移响应信号的连续小波变换值,并将振动微分方程组转换成用小波表示的线性方程组,求解不同时刻的线性代数方程组识别出时变结构的物理参数(质量、刚度和阻尼)。以5自由度时变结构为仿真算例,利用添加噪声的采集信号,识别了突变、线性变化和周期变化3种不同类型的时变物理参数,算例验证了识别方法的正确性、有效性和抗噪声能力。最后还研究了多尺度分析对参数识别的影响,给出了尺度参数区间选取和离散的依据。许鑫 史治宇 Wieslaw J Staszewski 龙双丽 2013振动工程学报2013,26,1:7
2混凝土中的Lamb波传播显示文摘将 PZT压电陶瓷片直接粘贴在混凝土梁表面来产生和接收超声波 ,由该系统发射不同频率的超声脉冲 ,依据接收的时域波形测量幅值最大波包在混凝土内的传播时间 ,由此得到波速随频率变化的频散关系。通过比较理论的与实测的频散曲线 ,表明 PZT系统能在混凝土内产生某些模态的 L amb波。在 5 0~ 10 0 k Hz的频率范围内 ,混凝土中的L amb波模态接近于 A3模态。而在 110~ 16 0 k Hz的频率范围内 ,L amb波模态接近 S4 模态。孙明清 Staszewski W J Swamy R N 2004武汉理工大学学报2004,26,1:6
