摘要: 由于磁流变阻尼器(Magneto-Rheological Damper, MRD)具有屈服、滞环饱和等强非线性特性，这使得磁流变(MR)悬架系统在不平路面激励的作用下产生复杂的非线性动力学行为，这是目前影响MR悬架系统得到实际推广应用的重要制约因素之一。本文基于改进天棚控制的二自由度悬架模型，分析了Sigmoid模型、修正Bouc-Wen模型、S型模型三种MRD计算模型在谐波路面激励下对MR悬架系统混沌响应的影响。结果表明在相同路面激励下，基于不同MRD滞环模型的悬架系统非线性动力学行为存在差异，基于Sigmoid模型的悬架系统在路面激励变化时的混沌抑制能力优于修正Bouc-Wen悬架系统和S悬架系统。
Abstract: Magneto-Rheological Damper (MRD) has strong nonlinear characteristics such as yield and hystere-sis saturation, which makes the magneto-rheological (MR) suspension system produce complex nonlinear dynamic behavior under uneven road excitation, which is one of the important con-straints affecting the practical application of MR suspension system. Based on the 2-DoF suspension model with improved skyhook control, this paper analyzes the influence of Sigmoid model, modified Bouc-Wen model and S model on the chaotic response of MR suspension system under harmonic road excitation. The results show that the nonlinear dynamic behavior of the suspension system based on different MRD hysteresis models is different under the same road excitation. The chaotic suppression ability of the suspension system based on Sigmoid model is better than that of the modified Bouc-Wen suspension system and the S suspension system when the road excitation changes.
