Abstract


Because the phenomena, drastic inclination or pitching or side sliding, which coach-buses behavour under the high-speed and dangerous occasion, basing on thinking the relative roll movement of passengers, the paper establishes the coach-bus dynamics model of nine-degree of freedom and the coach-bus dynamics model of fourteen-degree of freedom , which are verified by the experiments with true vehicle and adopted to study the maneuverability and stability of the high-speed coach-bus. The paper develops computer simulating software for each model with MATLAB language, by which the higher velocity and more dangerous occasions of the coach-bus are simulated. The paper also discusses the influential factors on the maneuverability and stability, such as, lateral stable pole, the position of gravity center, road adhesive coefficient, and so on, which provides the basis for the designing and safe running of the coach-bus.
