摘　　要：以一个二自由度汽车振动系统为研究对象,通过分析该系统中汽车悬架的振动形式及受力状况,求解该振动系统的数学模型和振动微分方程。运用Matlab软件编程求出汽车悬架的转角θ和质心位移X,绘出该振动系统响应的图像。求解过程简短,图像数据准确、明了,且符合振动学原理,显现了Matlab在求解此类机械振动系统的响应中的适用性和优越性,从而为求解一般机械振动系统的响应提供了简单有效的方法。Taking a two degree of freedom car vibration system as a research object, this paper solved the mathematical model and differential equation of the vibration system through analyzing the vibra- tion form and loading condition of automotive suspension. The comer θ and centroid displacement X of automotive suspension were solved in the Matlab program. In addition, Matlab software gave the image result of response of vibration system. Both the brief solution program and the accurate image data which corresponded with vibration theory showed the feasibility and superiority during solving these responses of mechanical vibration system. Thereby, this research provided an easy and effective method to solve the response of general mechanical vibration system with.
