基于正交实验法的弓网耦合除冰数值模拟
Numerical Simulation of Pantograph-Catenary Coupling De-icing Based on Orthogonal Experiment Method
摘要
Abstract
An investigation was conducted to examine the impact of the operating speed,ice thickness,pantograph head mass,pantograph head stiffness,and pantograph head damping on the de-icing rate.The investigation utilized the orthogonal experimental method and finite element simulation,employing a five-factor four-level orthogonal experimental design.Finite element models(FEM)were utilized to establish models for the ice-coating of the overhead contact system(OCS)and the coupling of the pantograph and catenary(PAC).The accuracy of the FEM was subsequently validated through a comparison between theoretical values and simulation results.The simulation results show that the operating speed and pantograph head mass have a significant impact on the contact force and contact wire lift amount,which in turn affects the de-icing rate.However,the influence of the pantograph head mass becomes less significant when it exceeds 17 kg.The results of the orthogonal experiment suggest that the de-icing rate is primarily influenced by the train speed,pantograph head mass,and ice thickness.The effects of pantograph head stiffness and damping are deemed insignificant.These results can provide references for improving train operation safety and PAC coupling de-icing technology.关键词
