Abstract

This paper describes the vibration phenomenon on vehicle motion from the perspective of energy propagation based on a two-degree-of-freedom vibration system. The energy transmissibility between the yaw and roll motions is analytically formulated by using their uncoupled natural angular frequencies, damping, and coupling characteristics. It is shown that the neutral steering character can be expressed by zero-energy transfer between the yaw and roll motion. The transmissibility is also useful to express the transient performance of the vehicle with under/over steering characteristics and the stable limit speed and so on. Finally, it is demonstrated that the transmissibility is useful to understand the transient performance under changing the roll stiffness and damping coefficient as examples.
