Abstract: In order to improve vehicle safety, the static properties analysis of rubber\|tired tram articulation system is conducted. Based on the introduction of the composition, function and characteristics of the articulation system, a static model of the vehicle body is established, the static equations of each articulated mechanism are derived, the static load of each articulated mechanism and the loading characteristics of the car body articulated system are analyzed. According to the force analysis, the static strength of the lower fixed hinge joint is simulated with the finite element analysis software ANSYS, and the results show that the fixed hinge strength meets the static requirements of the vehicle hinge system.
