Mixed-phase coupled vibrators

Donald T. Easley

A simple mechanical model for a vibrator is given. The equations governing the dynamic evolution of such a model vibrator are derived. A set of these model vibrators may be coupled through an elastic half-space with the vibrators upon the free surface. The equations describing the coupling of the vibrators through the half-space are derived. The final coupled system of equations provides a means to more realistically model the wavefield generated by a set of interacting vertical vibrators.
