从钢轨异常波磨研究反思地铁设计

Rethink about Metro Design from Rail Abnormal Corrugation Research

对近期北京地铁钢轨异常波磨治理研究过程从设计角度进行反思,包括振动控制技术的单一性、轮轨动力匹配等。提出今后轨道系统设计改进的思路与方向,包括设计应以实现其基本功能为核心、轨道减振设计应充分考虑其不利性、还"轨道减振"为"地铁减振"等,以及其他一些探讨性建议。

Based on the recent abnormal rail corrugation treatment and researches,from the design perspective,authors of the paper had a rethink about the unitary vibration control technology and the match of wheel and rail dynamic characteristics,etc.They propose the design ideas and direction to improve track system design,including： track system design should realize its basic functions as the core.The design for reduction of track vibration should consider disadvantages of itself;the concept of track vibration reduction should be transformed to metro vibration reduction as well as other tentative advice.
