Application of the statistical dynamic method. Study of a missile nose-cone in a reverberating acoustic environment
Abstract
Theoretical results relating to the statistical dynamic description of a structure are discussed. The provisional general scheme for calculating the spectral distributions and overall levels of the vibrations induced in the structure by a diffused type of random acoustic field is presented. The results obtained from a series of experiments carried out on a specimen missile nose-cone made from a composite material are presented and compared with those obtained by theoretical calculation.
