【 摘 要 】

Considering the limitation and inaccuracy of conventional simplified Maxwell model of yaw damper in the analyses of vehicle system dynamics, this paper established an accurate mechanical model of both one-way oil flow yaw damper and two-way oil flow yaw damper according to the analyses of their inner structure, and also contrasted two mechanical models of different oil flow direction and simplified Maxwell model in the vehicle system dynamics and analyzed the reason, especially in hunting stability, ride quality and small curve passability. The results show that the mechanical models of AMESim is superior than simplified Maxwell model in the accuracy of simulation.
