摘要

A prediction method was developed for noise induced structural vibration and sound transmission based on the concepts of statistical energy analysis (SEA). A general statistical energy program, GENSTEP, was written in FORTRAN ANS language which is capable of solving problems modelled by the SEA techniques. An experimental program was also performed in order to establish necessary SEA parameters for a range of typical spacecraft structural components. The computer predictions show a good agreement with the measured response of simple structures exposed to broad band reverberant noise. The limitations of the current method are defined together with suggestions for future development.
