This study presents a transient tire model for tire vibration characteristics due to uneven road surfaces. The model is composed of two parts—a static circular beam and a dynamic rigid ring. A new contact algorithm is developed based on the circular beam model, which can estimate contact pressure distribution by solving a set of linear equations. Tire vibration characteristics are then represented by combining the rigid ring model to the circular beam. Examples of contact pressure distribution and tire transient behaviors due to cleat tests are demonstrated and compared with measured data.
