Abstract
In this study a model was developed for the dynamic simulation of the motorcycle in which the frame was constructed using flexible elements. A feedback control system was applied to the model so that any given trajectory could be executed. The behaviour of the vehicle was analysed, determining the significant magnitudes at the following points: centre of front hub, centre of rear hub, steering column bearing and rear suspension attachment. Trajectories passing over a sinusoidal hump, in both acceleration and deceleration, and simulating an S bend were imposed. Analyses were conducted first considering the frame to be infinitely rigid and then considering it to be flexible. Comparing the results it was possible to determine when the frame must be schematised with flexible elements.
