| Abstract: | The vibration characteristics of the single freedom degree vehicle suspension system under the combined action of nonlinear spring and damping were studied.In the research,a single freedom degree nonlinear system dynamics model was established,the critical condition of chaos in the suspension system was analyzed by Melnikov method,and the threshold of orbital excitation amplitude when chaos in the sense of Smel's horseshoe occurs in the suspension system was obtained.The influence of linear stiffness,suspension damping and other parameters on the chaotic area of the suspension system was analyzed.When designing the parameters of a single freedom degree vehicle suspension system,the area where chaos occurs can be avoided. |
