摘要: Abstract The propagation of steady-state vibration in a periodic pipe conveying fluid on elastic foundation with an external moving load is studied using wave and attenuation theory. Wavenumbers properties coordinate system are investigated. constants calculated transfer matrix theory to determine whether the perturbation, which introduced by load, can propagate through or not. Bragg locally resonant band gaps, corresponding velocity field, exist system. In addition, effects both types gaps have been analysed.
