摘　　要：针对轨道几何不平顺检测中静态弦测标准体系不完善及动态、静态两种检测体系之间的关联关系不够清晰等问题,以高速动车组运行的安全性和舒适性波长范围为前提,在已有10 m弦、60 m弦中点弦测法评价标准的基础上,运用弦长传递函数,结合动力学仿真,增加了20 m弦长检测管理值,形成了10 m弦、20 m弦、60 m弦轨道几何不平顺静态弦测标准体系,并在实际高速铁路线路中进行试用。结果表明,该体系能够准确地控制高速铁路轨道不平顺,可以更好地指导养护维修。In view of the imperfection of the static chord measurement standard system and the unclear relationship between the dynamic and static inspection systems in the track geometric irregularity inspection,on the premise of safety and comfort of high speed EMU operation and on the basis of the existing evaluation standards of 10 m chord and 60 m chord midpoint chord measurement method,the 20 m chord length inspection management value was added by using the chord length transfer function and dynamic simulation,and the static chord measurement standard system of 10 m,20 m and 60 m chord track geometric irregularity was formed,which was used in the actual high speed railway line.The results show that the system can accurately control the track irregularity of high speed railway and guide the maintenance production better.
