摘要
通过建立弓网接触有限元模型,从多物理场相互影响的角度,综合分析了列车速度、弓网接触压力、弓网电流、环境温度对弓网接触区温度的影响,为弓网的实际生产运用提供建议和参考。
Via establishment of the pantograph-catenary contact finite element model,the effects of train speed,pantograph-catenary contact force,pantograph-catenary current and environment temperature on the temperature in the pantograph-catenary contact zone are analyzed comprehensively from the aspect of mutual affecting of multiple physical fields,providing suggestions and reference for the practical production and operation of the pantograph and catenary.
