Abstract

This paper deals with two-wheeled vehicle characteristics of steady state turning considering equivalent compliance for steering and suspension. In order to clarify the dynamics of two-wheeled vehicle at turning, we first measured tire characteristics. A steady state turning test was conducted using these tires to analyze the characteristics of the vehicle. Next, the steer characteristics and side slip characteristics were derived in consideration of the tire characteristics. From the difference between the experimental results and the analytical results, the equivalent tire characteristics were derived the equivalent cornering stiffness of front and rear tires. From these results, it is shown that the equivalent torsional compliance of the steering system and the rear suspension are derived from the relationship of the side slip angle. Finally, it is shown that we can describe expressing the characteristics of steady state turning quantitatively.
