摘　　要：为研究控制轻型车纵向用振动的作用机理,建立了二自由度车辆振动系统模型,利用控制理论的根轨迹法,分析了悬架刚度变化对系统瞬态性能的影响,确定了前、后悬架刚度的取值范围。Theory and mechanism of controlling light-truck pitch vibration were studied and two-degree freedom model of vehicle vibration system was set up. Using root locus method of control theory, this paper analysed the influence of suspension stiffness variation on the system transient characteristics and determined the range of stiffness values of suspension.
