Abstract
This paper is aimed at analyzing the chaotic vibration of a vehicle passing the consecutive speed control humps (SCHs) on a highway. A consecutive SCHs-speed coupling excitation function is presented. The chaotic vibration of nonlinear vehicle is studied by numerical simulation under a 2-DOF nonlinear vehicle suspension model. The chaotic vibration excited by the consecutive SCHs with different parameters is analyzed. Simulation results demonstrate that the chaotic motion may occur as the vehicle moves over a series of the consecutive SCHs. Furthermore, chaotic motion can be inhibited reasonably and effectively by proper adjustment of parameters of the consecutive SCHs.
