连续减速带参数对非线性车辆混沌振动特性影响研究

IThis paper is aimed at analyzing the chaotic vibration of a vehicle passing the consecutive speed control humps(SCHs) on the 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 influence of the chaotic vibrations with different parameters of the consecutive SCHs is analyzed.Researches show 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 adjusting the parameters of the consecutive SCHs properly.
