摘　　要：为探究外锁闭装置运动对尖轨转换力的影响机理,以与18号高速道岔配套的2种尖轨钩型外锁闭装置为研究对象,基于有限元方法建立模型,对轨腰处作用力与锁闭杆处作用力之间的传递函数关系进行了计算分析,并研究了夹异物对尖轨转换力的影响规律。In order to explore the influence mechanism of the external locking device’movement on the conversion force of the tongue rail,two kinds of external locking devices associated with the No.18 high-speed turnout are taken as research objects.And a model is established based on finite element method to calculate and analyze the transfer function relation between the force on the rail’s waist and the force on the locking rod.In addition,the influence rule of blocked foreign objects on the tongue rail’s conversion force is also studied.

关 键 词：高速道岔 外锁闭装置 尖轨转换力 传递函数
