At present, articulated vehicles are developing rapidly in China and articulated connectors are important parts of articulated vehicles. In March 2016, CRRC Qiqihar Rolling Stock co. LTD designed the GJ1 articulated connector. Due to the complexity of the articulated connector structure and stress distribution, it is necessary to study its loads in the application process. In this paper, the load identification of an articulated connector was mainly studied based on dynamic analysis. The dynamic model of the two coupling articulated vehicle was established. The relative motion relation of bump joints and the load conditions under some working conditions were analyzed. Finally, the finite element model was established and the static strength of the articulated connector was analyzed by means of the definition contact between the articulated connector parts. The results showed that the relative lateral displacement and relative side roll rotation angle of the concave and bump joints of the articulated connector were maximum in each working condition. More attention should be paid to the actual operation. The static strength of the main stressed parts of an articulated connector meet the design requirements. Since the material used for traction pin was not determined, high-strength tool steels T10 and T10A were recommended.
