Abstract:

Based on the primary principle of anti-vibration on vehicles, a chaos description on the vibration in suspensions is put forward.The vibration curve of the suspensions of test vehicles is obtained based on the data from a test rig for vehicle braking vs.suspension anti-vibration efficiency.The system parameters such as first inherent frequency and damp rate, as well as the chaos parameters such as the minimum embedding dimension and correlation dimension, are calculated by the vibration curve.The relationship among anti-vibration performance, chaos parameters and system parameters of vehicle suspension is presented.The research results show that the minimum embedding dimension M_min can be used to estimate the change of the anti-vibration performance of the front suspension of the off-road jeep.The smaller M_min is, the worse anti-vibration performance is. The corresponding stiffness and damp of the front suspension of the off-road jeep is smaller.Correlation dimension D₂2 can be used to identify different suspension types such as those of the off-road jeep and the car.The D₂2 of the off-road jeep is larger than the one of the car.
