This paper aims to build a rigid-flexible-liquid coupling rail vehicle dynamics model to study the lateral dynamics behaviour, which determines the vehicle hunting stability and running safety as well as ride quality. The liquid sloshing model is integrated into a simplified rail vehicle model concerning the nonlinear wheel/rail contact and deformable car body. The fluid element of the liquid sloshing model is a planar four-node rectangular element presented by the absolute node coordinate formulation (ANCF), which is employed to describe the large deformation of the free surface of the liquid inside container. The vehicle model accounts for the curving effects on the motion equations that influence the vehicle stability and curve negotiation. Verifications are performed to validate the fluid element efficiency, accuracy, and consistency, as well as the vehicle modes. Then the model is suitable for investigating the dynamic behavior of liquid carrier rail trains and its anti-sloshing.
