摘要
为提高基于麦弗逊悬架的轮式载具在矿山非结构地面中的平稳性与舒适性,对车轮与麦弗逊悬架进行建模,结合底盘的动力学模型对麦弗逊悬架关键参数进行设计。在ADAMS中建立了底盘的高保真模型,通过在不同摩擦因数的起伏路段进行运动仿真试验,验证了设计的麦弗逊悬架参数能够在起伏路段提高底盘的稳定性,降低底盘的起伏振动。研究证明,在起伏的矿山非结构场景中,麦弗逊悬架前侧较低的刚度系数与后侧较高的刚度系数相结合,可以提高底盘的驾驶舒适性与柔顺性,对矿山载具底盘的设计具有指导意义。
To improve the stability and comfort of wheeled vehicles based on McPherson suspension in unstructured ground of mine,the wheel and McPherson suspension were modeled,and the key parameters of McPherson suspension were designed based on the dynamic model of the chassis.Then,a high-fidelity model of the chassis was established in ADAMS.Through the motion simulation tests on undulating road sections with different friction coefficients,it is verified that the designed McPherson suspension parameters improved the stability and reduced the undulating vibration of the chassis.This study proved that in the undulating unstructured scene of mine,the combination of the lower stiffness coefficient at the front side and the higher stiffness coefficient at the rear side of McPherson suspension could improve the driving comfort and flexibility of the chassis,which had guiding significance for the design of the mine chassis.
