Simulation Study On Direction Stability Of Bus Braking

As the fast development of the modern construction,the superhighway and bus technical will increasingly perfect,these provide a kind of convenience trip for pepole. But the safe problem can't be neglected,this puts forward a series of design request in the bus development and the research process. The safety is important to the direction stability in bus braking,so the study of direction stability is necessary .Under this kind of premise,with object of HFC6801 this paper through Matlab/Simulink establishment eight freedom degrees simulative model which contain longitudinal,lateral,yaw and four wheel .front wheel rolling.Under the condition of wether install ABS,through the simulation of line braking in road that is 'D'.'G' and 'DK' road prove the important effect with ABS.Afterwards,through without ABS braking simulation analyze the direction stability about wheel lock sequence.As a result ,at rear wheel lock the turning ability is better than lateral disturb .however at front wheel lock the lateral disturb ability is better than turning.With the PC development .Virtual reality technique(VR) will be used more and more fields. So for vehicle this technique is not exception.In this paper,combine with VR and Matlab/Simulink simulation is feasible for simulated test. Have experience for the follow up research.
