摘要
减小轮轨磨耗是提高轮轨使用寿命、降低运营成本的有效方法,而轮轨摩擦系数是影响轮轨磨耗的重要因素。在SIMPACK软件中建立C80多体动力学车辆模型,利用计算机仿真研究方法对轮轨综合摩擦控制对于轮轨磨耗的影响进行研究。结果表明,在直线区段不建议采用轮轨润滑作业,而在曲线区段建议采用轨顶、轨侧综合摩擦系数控制方法进行涂敷作业,且轨顶、轨侧适当摩擦系数配比的异步润滑模式具有较好的轮轨减磨效果。
Reducing wheel-rail wear is the effective way to improve the life of the wheel-rail and reduce operating costs, at the same time, wheel-rail friction coefficients is the significant impact element of wheel and rail wear. Setting multi-body dynamics model of C80 vehicle on the SIMPACK software, study the impact of Comprehensive friction control on tread and side track about wheel-rail wear by computer simulation methods. The results showed that in the straight section wheel-rail lubrication job is not recommended, but in the curve section comprehensive friction control on both tread and side track is recommended to lubricate, Asynchronous lubrication method with properly friction coefficient ratio of tread and side track has a good effect on grinding wheel and rail.
