Research of Tire Rolling Radius Based On the Finite Vibration Unit Model

This paper established the finite vibration unit model and solved the response of each unit system. And it analyzed the unit vibration. Based on the model it introduced the calculation method of rolling radius. Next this paper simulated rolling radius and the relationships between the rolling radius and the vehicle speed, the tire pressure, and the load using MATLAB software. And the relationships were modified according to the real vehicle test. Finally, the tire rolling radius calculation method was discovered at high speed.
