广州地铁8号线车辆制动参数对轮对、闸瓦的影响分析及优化

Influence of Braking Parameters on Vehicle Wheel Set and Brake Shoe on Guangzhou Metro Line 8 and Optimization Scheme

基于广州地铁2、8号线拆分后对8号线列车轮对、闸瓦磨耗及轮对病害的数据统计,总结以往的试验成果,分析不同制动参数对轮对、闸瓦磨耗及轮对病害的影响;综合定量成本分析,得出现阶段最优制动参数方案。此外提出了后续的优化思路和方向。通过优化制动参数降低了轮对、闸瓦磨耗,减少了轮对病害,达到了节约维护成本的目的。

Based on the data statistics of wheel set,brake shoe wear and wheel set diseases on Guangzhou metro Line 8 after the split with Line 2,the previous test results are summarized,the impact of different braking parameters on wheel set,brake shoe wear and wheel set diseases is analyzed.On the basis of quantitative cost analysis,the optimal braking parameter program at this stage is obtained.In addition,the follow-up optimization ideas and directions are further proposed.The optimization of the braking parameters has effectively reduced the wear of wheel set and brake shoe,as well as the wheel set diseases,achieved the goal of saving maintenance cost.
