Typical Operating Conditions The Bus High-speed Handling And Stability Studies

This paper presents a theoretical study of maneuverability and stability of coach-bus via modeling, verification and simulation.For this end, a dynamic model with many degrees of freedom is built on the basis of coach-bus made in China and a synthesis of various gaits. This model, capable of simulating extreme driving maneuvers with MATLAB/Simulink, brings out precise results that match the experiment results perfectly. Corresponding simulation results are achieved too by feeding the model correlative parameters altered as per the research requirements, such as the position of gravity, configuration, lateral stable pole, side wind, etc. An analysis and study is thereby made on the maneuverability and stability of the coach-bus.In this paper, the dynamics model has some characters of nonlinearity and a new evaluation index ,by which simulation consequencose can be evaluated, be researched and be put forward.
