【Abstract】 Based on the dynamic simulation of pantograph-catenary coupling system and the orthogonal experimental design method, the effects of six structural parameters of DSA250 pantograph on the dynamic current-collecting performance of rigid Metro pantograph-catenary system with a speed of 160km/h were studied, and the optimal combination of parameters was selected, and the influence degree of each parameter was sorted. The results show that the selected optimal combination parameters can significantly improve the dynamic current-collecting quality of pantograph-catenary system. Among the six structural parameters, the pantograph head mass has the greatest influence on the dynamic current-collecting performance of pantograph-catenary system, while the upper frame mass has the least influence on the current-collecting performance.更多还原
