RADSPHERE - A Computer Program for Calculating the Steady-State, Axially Symmetric, Forced Response and Radiation Field of a Submerged Spherical Shell.
Abstract
A computer program, RADSPHERE, has been developed for calculating the axisymmetric forced vibration response and sound radiation of a thin, elastic, spherical shell, submerged in an infinite fluid. Four cases of excitation are provided: (1) a concentrated radial load acting at a point on the shell surface, (2) two such loads acting simultaneously at antipodal surface points, (3) a uniform load distributed over a sector of the surface, and (4) two sector loads acting simultaneously with respect to an axis of the sphere. The calculated quantities are the shell surface radial velocity and the acoustic pressure at both the shell surface and in the far-field. RADSPHERE results are generated in tabular form and in graphic form, the latter through use of a companion program PLOTTER which provides an interface with the facilities of the software package DISSPLA.
