Dynamics of a Strongly Nonlinear Spacecraft Structure Part II: Modal Analysis

Year: 2014

Type: conference-paper

Abstract: The present paper investigates the dynamics of a real-life spacecraft structure possessing a strongly nonlinear com-ponent with multiple mechanical stops. A full-scale finite element model is built for gaining additional insight into the nonlinear dynamics that was observed experimentally in a companion paper [NRK14]. To this end, advanced techniques and theoretical concepts such as numerical continuation and nonlinear normal modes are exploited. Key words: Spacecraft structure; piecewise-linear non-linearities; numerical continuation; nonlinear normal modes; modal interactions. 1.
