| 摘 要： | 基于磁流变减振器的汽车悬架系统具有明显的滞后非线性，分析了其在单频正弦激励下的1／3亚谐共振(即其固有频率为路面激励频率的1／3倍)时的情况，利用平均法得到了其幅频特性方程，研究了非线性刚度和非线性阻尼对系统的影响，并指出系统此时的亚谐共振为叉型分岔。

| Abstract: | Automobile suspension system based on the hydromagnetic damper is a typical retarded nonlinear system. This paper analyzes on the case that the inherent frequency of the system is 1/3 times of the frequency of sinusoidal force produced by the road, obtains its amplitude frequency characteristic equation by using the average method, studies on the influence of the nonlinear rigidity and the nonlinear damp on the system, and points out that the sub-resonance of the system in this case is the fork-type bifurcation. |

| Keywords: | sub-resonance automobile suspension system nonlinear dynamic feature |
