Abstract
Waves are considered excited by a moving-oscillating load in a general uniform waveguide with uniformly distributed and localized dynamic structures. In its order, the load frequency and speed define the waveguide frequency. Asymptotic solutions are obtained based on three parameters corresponding to the exciting wave frequencies: the phase and group velocities and the dispersion number (the second derivative of the frequency). We also present descriptions of the quasi-front and the resonant waves. The waveguide response under the load determined allowed us to find the phase shift between the oscillating force and the (energy flux related) waveguide speed.
