摘要
Abstract
Waves,propagating from sources in mechanical systems,dissipate on the way of propagation and transmit via obstacles--boundaries of subsystem with source. Only the residuary part of input power consumes on formation of reverberant field in subsystem. Such processes are taken into account for improve-ment of computing vibration and noise using Statistical Energy Analysis(SEA). Expressions for input pow-er,injected into simple beams system,are presented as an example. It is shown that influence of propagat-ing waves on calculating results increases when loss factor increases. Practical possibility to take propagat-ing waves into account for complex spatial systems like ships is considered. Estimations show that it is suffi-cient to consider propagating waves only in subsystems with sources.关键词
