APPLICATION OF FINITE ELEMENT MODELLING TO THE PREDICTION OF INTERIOR NOISE LEVELS OF AN ARMOURED PERSONNEL CARRIER

A formalism is presented for incorporating modal output data from finite element structural models into the more conventional framework of space and frequency averaged vibrational response and interior noise predictions. The methodology is applied to calculation of interior noise- to- force transfer functions for an armoured personnel carrier with good results. Considerable computational cost savings and more convenient and improved data interpretation result from the use of the outlined method. (Author/TRRL)
