Abstract

By manipulating the mode shapes of a structure, a noisy, strong-radiator mode can be converted into a quiet, weak-radiator mode. The approach taken here is to use optimization techniques to place small point masses at strategic locations on the structure so as to alter the mode shapes and turn the structure into a weak radiator. The end product of this effort is the SOAR (Shell Optimization for Acoustic Radiation) computer code which consists of a finite element based vibration prediction code in combination with a boundary element/wave superposition method for predicting sound power.
