Modelling and Stability Analysis of Articulated Vehicles

This study constructs a nonlinear dynamic model of articulated vehicles and hydraulic steering system. The equations state required for vehicle dynamics models, stability analysis corresponding eigenvalue are obtained by constructing Newtonian mechanical equilibrium equations. objective subjective causes the snake oscillation relevant indicators evaluating instability analysed using several parameters. influencing factors specific action mechanism combining method with multiple centre mass position system have more substantial influence on than other Vehicles can be in complex snaking deviating. Different eigenvalues varying effects different forms instability. critical velocity linear through is relatively lower model.
