Abstract
This paper presents a modeling approach of shaking-table considering reaction force of a specimen using multi-flexible body simulation. Reaction force generated by resonant vibration of the specimen generally deteriorates the reproducibility of acceleration. In order to simulate behaviors of the shaking system including effects of the reaction force, a multi-flexible body technique is adopted, where the specimen is defined as a flexible component to reproduce the reaction force.Effectiveness of the constructed model is comparatively verified by experiments with numerical simulations.
