A semi-analytical model for predicting multiple propagating axially symmetric modes in cylindrical waveguides.

摘要: Abstract A semi-analytical model for multiple mode axially symmetric wave propagation in finite solid cylindrical waveguides is presented. The designed as a tool predicting and interpreting experimental signals. based on common configuration considers the excitation, reception of ultrasonic signal waveguide. Pochhammer–Chree solution an infinite cylinder basis model. Extensions are made to enable comparison results. Comparisons with experiment performed time, frequency joint-time domain both narrow band broad excitation piezo-electric transducer.
