Abstract
The purpose of this study is to understand the steady turning behaviors of eight-wheeled vehicle. First, an eight-wheeled independent steering vehicle model has been developed, and its motion equations based on the geometry and force equilibrium of the vehicle are derived for the steady state analysis. This model has included eight independent steering angles, slip angles, load transfer, and the model of tire of heavy duty vehicles. Applying numerical method on the model, numerical solutions can be found. The solutions can be used to investigate the steady turn behaviors of eight-wheeled vehicles which can cornering by the two axes in the front. Then, the effects of three axes steering have been studied. In addition, with holding the steering angle of two axes in the front, the effect of fourth axes steering have also be investigated. By using this model, the slip angle, cornering force and load transfer of each tire can be thoroughly realized. Finally, according to the tire characteristic above, the steady turning behaviors of eight wheel vehicle can be described.
