Paper Abstract

An effort to model the dynamic motion of an ionic-polymer metal composite elestic beam was undertaken. Development of the static portion of the model was begun by assuming the beam behaves in accordance with the nonlinear equation used to describe large-angle deflection of elastic cantilever beams. A Simulink simulation was developed to estimate the final deflection of a beam due to a constant moment. The dynamic portion of the model was developed by assuming that each segment of the beam could be represented as a simple second-order system. Future efforts to more accurately model beam motion - by modifying the method used to model the forcing moment, by expanding the model to predict the performance of beams of all dimensions, and by validating model performance against actual beam motion - were recommended.
