Abstract

Abstract:

The distribution parameter dynamics equation of flexible appendages during extension is derived based on Hamilton principle. The dynamic behavior, especially the characteristic of the response to harmonic excitation is discussed in detail. It is concluded that dynamics characteristics of extensional appendages result in increasing the possibility of structure failure when it is under excitation of external force.

Key words: dynamics, time- var ying system, ext ension, flexible appendages
