Abstract: The application of the rigid ring tyre model, in combination with a new enveloping model with elliptical cams, mounted in a quarter vehicle system is described for both specific obstacles, like potholes and bumps, and measured road profiles that fit the general category of ||broad-band random signals||. Validation results of both the tyre and vehicle models are presented. In addition, the models are analysed extensively to obtain insight into how the vehicle system behaves and to investigate how the enveloping model that generates an effective road surface contributes to this behaviour.

Keywords: durability; quarter vehicle model; ride comfort; road profiles; rigid ring tyre model; vehicle dynamics.
