Abstract :This paper demonstrates how flexural wave propagations in a thin plate can be modelled by estimating the combined effect of the excitation and the sensor. A theoretical model for flexural wave propagation in thin plates is derived and it is compared with measurements. In addition, the performances of used filters and ARX insert ignore into journalissuearticles values(autoregressive exogeneous); model are compared on estimating the wave propagation in a thin quartz glass plate. Results indicate that the most accurate estimation of wave propagation is obtained when a linear phase filter which attributes all dispersions to the wave is used.
Keywords : Flexural waves, filtering, ARX modeling, estimation of wave propagation
