摘要
将汽车底盘减振装置简化为以非线性弹簧、阻尼器为主的被动阻尼式吸振器.利用Matlab软件对其在简谐力作用下的响应进行定量绘图分析,研究其振幅衰减、缓冲周期以及与由线性弹簧构成的简单模型进行比较,解释了减振装置具体的工作过程以及其中的基本工作原理.
This article simplified the shock absorbers system of cars as a passive damping ab- sorber model which mainly consisted of nonlinear spring and damper. We quantitatively plo- tted and analyzed the response of our model under a simple harmonic force with the Matlab software to study its amplitude attenuation and cushioning period. We made a comparison be- tween our model and the model of linear spring shock absorbers to explain the technological processes and basic work theorem of the whole damping system.
