Abstract:
In order to analyze and evaluate the performance of the air suspension system of heavy trucks with semi-active fuzzy control, a three-dimensional nonlinear dynamical model of a typical heavy truck with 16-DOF(degree of freedom)is established based on Matlab/Simulink software. The weighted root-mean-square(RMS)acceleration responses of the vertical driver’s seat, the pitch and roll angle of the cab, and the dynamic load coefficient(DLC)are chosen as objective functions, and the air suspension system is optimized and analyzed by the semi-active fuzzy control algorithm when vehicles operate under different operation conditions. The results show that the influence of the roll angle of the cab on the heavy truck ride comfort is clear when vehicles move on the road surface conditions of the ISO level D and ISO level E at a velocity over 27.5 m/s. The weighted RMS acceleration responses of vertical driver’s seat, the pitch and roll angle of the cab are decreased by 24%, 30% and 25%, respectively, when vehicles move on the road surface condition of the ISO level B at a velocity of 20 m/s. The value of the DLC also significantly decreases when vehicles operate under different operation conditions. Particularly, the DLC value of the tractor driver axle is greatly reduced by 27.4% when the vehicle operates under a vehicle fully-loaded condition on the road surface condition of ISO level B at a velocity of 27.5 m/s.
为了分析和评价具有半主动模糊控制的重型卡车空气悬挂系统性能, 基于Matlab/Simulink软件建立了具有16自由度的三维非线性动力学模型.以座椅的平均垂直加速度响应、驾驶室的俯仰和倾斜角及动载系数(DLC)为目标函数, 用半主动模糊控制方法对不同工况下的车辆空气悬挂系统进行了优化分析.结果表明:在ISO D级和ISO E级路面上, 当车速超过27.5 m/s时, 驾驶室侧倾角对重型卡车乘坐舒适性影响非常明显;在ISO B级路面车速为20 m/s时, 车辆座椅的平均垂向加速度、驾驶室俯仰角及驾驶室倾侧角分别降低了24%, 30%和25%.此外, 在不同路况条件下, 车辆的动载系数均有较大的降低.特别地, 在ISO B级路面车速为27.5 m/s且满载时, 车辆驱动轴处的动载系数降低了27.4%.
