Aircraft anti-skidding braking system (ABS) was a nonlinear mechatronics system influenced by various factors. The road-wheel friction was one of the key factors affect system dynamics, which depends both on vertical contact force and skidding ratio. However, the vertical contact force was generally considered as constant in existing simulation and analysis methods. This paper investigated a simulation method considering dynamic vertical contact force and its influence on system dynamics. It was found that the landing gear shock absorber of aircraft leaded to dynamic vertical wheel-road contact force, and had significant influence on braking distance. The influence of dynamic vertical contact force was analyzed under three conditions. The proposed method considering dynamic contact force could significantly enhance the accuracy of aircraft anti-skidding braking system s imulation.
