Research On The Operation Stability Of The Mini Bus

In order to improve the handling stability of the minibus, this paper analyzed the minibus’s handling and stability by dynamics theory, combined with the simulation. First, the paper analyzed the vehicle’s handing stability research method of domestic and foreign experts, and presented the main research contents. Besides, the paper provided the standard method of handling stability evaluation in this study. The car simulation model was established in this paper on the basis of the actual model structure size parameter. Then the model was simulated for dynamics analysis and acquired the handling stability evaluation conclusion. Finally, some variable parameter was adjusted in order to so as to improve the handling stability and some optimization was presented. The result demonstrated that the handling stability of the vehicle, as a whole, met the requirement, the steady turning performance was ordinary. The steady response was improved by the optimization project presented, which also improved the overall performance level. The study lays groundwork for the security improvement of minibus.
