Abstract
为了提高客车的防侧翻能力,建立了4自由度的客车整车动力学模型,并以此为基础设计了半主动悬架防侧翻控制器,提出了一种基于半主动悬架的模糊滑模控制策略.在MATlAb/SIMulInk环境下进行了仿真计算,仿真结果表明:采用所提出的模糊滑模控制策略,可以有效地降低汽车非直线行驶时的侧倾角以及侧倾角速度,提高汽车的侧翻稳定性,降低汽车侧翻事故发生可能性.
 
For purposes of improving the ability of anti rollover for buses,a 4degree of freedom bus rollover dynamics model is established,and a fuzzy sliding mode control strategy is proposed based on semi-active suspensions for buses.Under MATLAB/SIMULINK,simulations are conducted.Results show that the proposed control scheme not only can reduce roll angles and roll angular velocities,but also can improve the roll stability of buses and reduce the possibility of bus rollover accidents.
