| 摘 要： | 在虚位移分析基础上，利用拉格明日方程推导并建立了单侧前独立悬架系统线性四自由度动力学模型，并利用此模型进行了系统在不同激振力作用下强迫振动响应计算方法的探讨。编制了相应的计算机程序。建立的数学模型和计算方法反映了单侧前独立悬架系统（整车了结构之一）的动力学特性，有助于悬架的设计及汽车动力学问题的研究。

| Abstract: | Based on virtual displacement analysis, a linear model of four degrees of freedom is established in terms of Lagrangian equations to analyse the dynamic characteristics of automobile front wheel independent suspension system (single side). With this model, a calculation method for forced vibration response to various exciting forces is studied. The model and calculation method are useful in automobile suspension design and vihicle dynamic research |
