The hydraulic anti-kink system is an important safety system for low-floor trams, which is used to prevent unnecessary displacement and motion of a single carbody tram. According to the structure and working principle of the hydraulic anti-kink system, the mechanism of the hydraulic anti-kink system is studied and the mathematical model of the hydraulic anti-kink system is derived. Meanwhile, the influencing factors of the stiffness and damping characteristics of the system are analyzed. A 4 modular 100% low-floor tram simulation model was established by SIMPACK/SIMULINK, the influence of the hydraulic anti-kink system on the dynamic performance of the tram in the small radius curve passing is studied. The effects of the anti-kink system on typical vehicle traction/brake fault and push rescue conditions are investigated. The result shows that: the anti-kink system can well constrain the motion posture of the tram during the small radius curving, so that the trajectory of each carbody is consistent, and the lateral offset of the vehicle body is reduced; and in typical vehicle traction/brake fault and push rescue conditions, the Z-shaped bending caused by the mutual squeezing between the modules of the vehicle can be prevented, and the derailment of the vehicle can be effectively prevented when a tram with anti-kink system installed. The dynamic simulation model of the anti-kink system is verified by experiment.
