摘　　要：为改善某商用车的对地友好性,以某重型货车为研究对象,建立了1/4车体的动力学模型,研究悬架参数对道路友好性的影响,运用优化方法对悬架刚度和阻尼进行优化设计。并在此基础上,以提高道路友好性为目标并兼顾振动舒适性,研究阻尼可调减振器的半主动悬架的控制,结果表明,相对于被动悬架,采用最优模糊控制的半主动悬架车辆道路破坏系数有较大幅度的降低。To improve the road friendliness of commercial vehicles, the dynamic model of a heavy duty truck is established, and the influence of suspension parameters of the truck on the road friendliness is studied. The suspension stiffness and damping are optimized. On this basis, the adjustable damping shock absorber and the semi-active suspension control are applied to improve the road friendliness. The results show that, compared with the passive suspension, the road damage coefficient of the optimal fuzzy-control semi-active suspension is greatly reduced, and the ride comfort is also improved at the same time.
