　　In this paper, the dynamic behavior of a nonlinear eight degree-of-freedom ground vehicle model is examined.The nonlinearity occurs due to suspension dampers and springs.The disturbances from the road are assumed to be sinusoid and the time delay between the disturbances is considered.Using bifurcation phenomenon.the chaotic motion is detected and confirmed with the Poincare maps.Results show that changing system parameters can be used as an instrument to easily eliminate the chaos or minimize the vibration to the passenger seat.The results can be applicable in dynamic design of a vehicle.
