研究了车辆悬架系统的动态特性和减振器阻尼对其特性的影响。重点分析了农用运输车用气柱式减振器中气柱力的影响 ,得出了气柱弹簧刚度在减振器压缩和拉伸行程中的变化规律。指出如何利用上述规律和有关的性能试验获得阻尼系数或直接采用模拟实际工况的激振试验得出相应悬架系统的动态性能
The dynamic characteristics of the vehicle suspension system and the damping of the shock absorber on its characteristics are studied. The influence of the air column force on the air column shock absorber used in farm vehicles was analyzed. The variation law of the air column spring stiffness in the compression and tension stroke of the shock absorber was obtained. It is pointed out how to obtain the damping coefficient by using the above law and the related performance test or directly using the excitation test simulating the actual working condition to get the dynamic performance of the corresponding suspension system
