Scholte波波速和孔隙度关系的建立及实验验证
|
摘要
随着声学技术的快速发展,界面波在无损检测及环境参数反演领域的应用越来越广泛,但是目前理论与实践之间还存在一些差距,首先对基于Biot理论的流体饱和多孔介质声传播特性的理论进行了仿真分析,然后运用势函数结合多孔介质固体-流体边界条件建立了两半无限空间流-固界面Scholte波理论模型,最后对这一理论模型进行了实验验证。仿真结果表明:声波频率对各种波速几乎没有影响,但各种波速随孔隙度的变化较大;通过实验验证:Scholte波波速理论值与实际测量值之间的相对误差不超过0.24%。
With the rapid development of acoustic technology,interface waves are widely used in the fields of nonde-structive testing and environmental parameter inversion.But,so far there still exist some gaps between theory and prac-tice.Simulation analysis of sound propagation characteristics based on the Biot theory of fluid-saturated porous medium is firstly made.Then the potential function combined with porous medium-fluid boundary conditions are used for the establishment of the theoretical model of Scholte wave in two semi-infinite spaces' fluid-solid boundary.Finally this theoretical model is verified by experiments.Simulations show that the acoustic frequency almost has no impact on the wave velocities of different waves,but the wave velocities change greatly with the porosity of medium.Experimental results show that the error between the theoretical value and the actual measured value of the Scholte wave velocity does not exceed 4.2m/s.
