| Abstract | The consistency of the dynamic behavior of the mechanical equivalent model of high-speed pantographs with that of actual high-speed pantographs under service conditions is crucial for the correctness and accuracy of the numerical simulation results of the pantograph-catenary interaction. Firstly, based on experimental data and the finite element method, models of a mass-point frame and reduced pan head were established, which can simulate the rolling and pitching motion characteristics of the dual-strip pan head. The correctness of the finite element numerical simulation of the pantograph-catenary system based on the model was verified through an industry standard and line tests. Then, the variation law of the standard deviation of the contact force (SDCF) in the speed range of 240-450 km/h was studied, and the mechanism of large fluctuation in SDCF was explained from the perspective of pantograph-catenary resonance. Finally, the influence of pan head degree of freedom and low-pass filtering frequency of the contact force time-domain signal on SDCF was studied, and the applicable speed level of the traditional three-mass model and 20 Hz filtering were provided. |
