Abstract

This paper presents a symbolic approach for linearization of differential and algebraic dynamic equations. This technique avoids the drawbacks of the numerical perturbation method and eliminates the need to set up thelinearized constraints library. Several examples have been used tovalidate the procedure. Included is the stability analysis of six DOFrailway car model.
