摘要
The significant increase in speed of high-speed train will cause the dynamic contact force of the pantograph-catenary system to fluctuate more severely,which poses a challenge to the study of the pantograph-catenary relationship and the design of highspeed pantographs.Good pantograph-catenary coupling quality is the essential condition to ensure safe and efficient operation of high-speed train,stable and reliable current collection,and reduction in the wear of contact wires and pantograph contact strips.Among them,the dynamic parameters of high-speed pantographs are crucial to pantograph-catenary coupling quality.With the reduction of the standard deviation of the pantograph-catenary contact force as the optimization goal,multi-parameter joint optimization designs for the high-speed pantograph with two contact strips at multiple running speeds are proposed.Moreover,combining the sensitivity analysis at the optimal solutions,with the parameters and characteristics of in-service DSA380 highspeed pantograph,the optimization proposal of DSA380 was given.
高速列车的大幅提速,将导致弓网动态接触力振荡更加剧烈,给弓网关系研究和高速受电弓设计提出了挑战.良好的弓网耦合质量是确保高速列车安全高效运行、稳定可靠受流、降低接触线与受电弓滑板磨耗等的基本前提.其中,高速受电弓的动力学参数对弓网耦合质量至关重要.本文以降低弓网接触力标准差为优化目标,提出了多个运行速度下的双滑板高速受电弓的多参数联合优化设计方案.此外,结合最优解处的敏度分析,以及DSA380型双滑板高速受电弓的现役参数和服役特点,给出了DSA380的优化建议.
