摘要
跨座式单轨列车作为一种新型城市轨道交通系统,其受电弓系统的设计与性能直接影响列车的安全稳定运行。对重庆四方某公司研发的轨道交通跨座式单轨列车受电弓(以下简称四方受电弓)系统设计与性能进行了深入分析。通过建立受电弓接触网耦合动力学模型,采用有限元分析和多体动力学仿真方法,对四方受电弓的结构设计、材料选择、接触力特性及动态响应进行了系统研究。研究结果表明,优化后的四方受电弓结构能够降低接触力波动,提高受流稳定性,在列车运行速度达到80 km/h时,接触力波动控制在标准范围内,接触力均值保持在70~90 N。同时,通过改进受电弓的减振系统和滑板材料,显著降低了受电弓的振动幅度,提高了受流质量。四方受电弓相比传统受电弓具有更好的抗风性能和更高的可靠性,能够适应复杂多变的运行环境。研究为跨座式单轨列车受电弓系统的优化设计提供了理论依据和技术支持,对提高列车运行安全性和稳定性具有重要意义。
As a new type of urban rail transit system,the design and performance of the pantograph system of straddle-type monorail trains directly affect the safe and stable operation of the trains.This paper conducts an in-depth analysis on the design and performance of the pantograph developed by Chongqing XX Sifang XXX Co.,Ltd.(hereinafter referred to as Sifang pantograph)for straddle-type monorail trains in rail transit.By establishing a pantograph-catenary coupled dynamics model,and using finite element analysis and multi-body dynamics simulation methods,a systematic study is carried out on the structural design,material selection,contact force characteristics and dynamic response of the Sifang pantograph.The research results show that the optimized structure of the Sifang pantograph can effectively reduce thefluctuation of contact force and improve the current collection stability.When the train speed reaches 80 km/h,the contact forcefluctuation is controlled within the standard range,and the average contact force remains between 70-90 N.At the same time,by improving the damping system and slider material of the pantograph,the vibration amplitude of the pantograph is significantly reduced,and the current collection quality is improved.Compared with traditional pantographs,the Sifang pantograph has better wind resistance and higher reliability,and can adapt to complex and changeable operating environments.The research provides a theoretical basis and technical support for the optimal design of the pantograph system of straddle-type monorail trains,and is of great significance for improving the safety and stability of train operation.
