大客车侧翻稳定性分析及防侧翻鲁棒控制
Analysis of Roll Stability and Robust Control of Rollover Prevention for a Bus
摘要
Abstract
Bus rollover is a serious traffic accident.To obtain rollover stability and improve the handling stability caused by vehicle rolling,the rollover stability and anti-roll control strategy of a bus are studied.Taking the unsprung mass and the number of passengers variation into consideration,a linear four degrees of freedom model is established to describe vehicle motions,including lateral,yaw and roll motion of the sprung and unsprung mass.From the law of vehicle rollover dynamics,a rollover index is put forward to evaluate the rollover performance of the bus.Also,the game theory and the theory of Nash equilibrium are applied to design a robust control strategy.Furthermore,the rollover stability,the handling stability of the bus,and the robustness of the anti-roll control system are analyzed by typical numerical cases.And the theoretical results are verified by the Trucksim simulation experiment.The results show that the robust control strategy can prevent bus rollover with good dynamic performance and robust stability.关键词
