摘要
悬架系统是机动车上的重要部件,其性能的好坏对车辆的平顺性、操纵稳定性和安全性等都有重要的影响。而悬架数学模型的精确性、合理性对悬架的研究起到决定作用。本文以汽车整体为研究对象,进行了力学分析,根据牛顿运动定律推导出悬架各部分的力学微分方程,从而建立了七自由度悬架系统模型,为汽车主动悬架的进一步研究提供了理论基础与依据。
Suspension systems are important components of motor vehicles, whose performance has a major impact on the vehicle ride comfort ,handling stability and security in the research of suspension. The accuracy and reasonableness of the mathematical model play a decisive role. Through the mechanical analysis of overall vehicle, the mechanical differential equations of suspension parts are deducted according to Newton＇ s Laws of Motion in this paper. Finally, a seven DOF suspension system model is established ,which provides theoretical basis for the further study of automotive active suspension.
