| Abstract: | The elemental theory of chaos characteristics parameters such as correlation dimension and maximum Lyapunov exponent are introduced.By a test rig for automobile braking-suspension anti-vibration efficiency,the vibration curves of front and rear suspension of BJ2020S road-off jeep and HONDA LEGEND 3.0 car are obtained quickly.The one-order nature frequency,damp ratio,power in the band with the one-order nature frequency and the chaos' characteristics such as correlation dimension and maximum Lyapunov exponent are calculated through the vibration curve.The relationship between the anti-vibration performance and chaos' characteristics parameters of automobile suspension are presented.The fast determination for anti-vibration performance of automobile suspension is realized. |
