1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
2压电陶瓷片用于检测混凝土的波速和动弹模显示文摘将 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 ,从接收的时域信号中能清晰分辨沿混凝土梁表面传播的纵波和 Rayleigh波 ,并以此确定 Rayleigh波和纵波在混凝土表面的传播时间和波速 ,再由 Rayleigh波和纵波波速计算混凝土的动弹性模量和动泊松比。PZT片产生的沿表面传播的纵波和 Rayleigh波用于混凝土内结构缺陷监测时 ,合适的频率范围分别为 12 0~ 2 0 0 k Hz和 5 0~ 110 k Hz,并且 Rayleigh波波速在 5 0~ 80 k Hz的频率范围内呈现出明显的频散特性 ,即波速随频率而变化。孙明清 STASZEWSKIW J SWAMY R N 2004武汉理工大学学报2004,26,6:4
