Vertical dynamic response of a high speed passenger car considering elastic vibration has been investigated, in which car body is modeled as a simple uniform elastic Euler-Bernoulli beam with free ends. It is found that vibration in the elastic model is bigger than in the rigid one. In order to reduce the vertical flexural vibration, an effective and practical method is introduced, which is to paste free damping layers on the outside sheathing of the car body. The calculations show that it is a useful measure for improving the riding comfort of the high speed car. The thicker the damping materials attached, the better the ride comfort will be. But considering the weight it may introduce, only 3mm bitumen based damping materials is enough to get a satisfactory result.
