摘要
为了直观、快速地设计道岔区轮轨关系,在道岔区轮轨静态接触理论的基础上,通过独立车轮垂直振动和单轮对蛇形运动的分析,建立了道岔动力参数设计法.用该方法对18号高速道岔转辙器部分轨距加宽设计进行了分析,得到了最大轨距加宽量为15 mm,最大加宽位置在尖轨顶宽30 mm处,轨距加宽范围为21.743 m的较优方案.列车道岔系统动力学验证和运营实践证明了该方法的正确性.
In order to design the wheel-rail relation in turnout intuitively and quickly, a dynamic parameter design method for turnout was put forward based on the static contact theory of wheel-rail in turnout and by analyzing the vertical vibration of independent wheel and the hunting motion of single wheelset. No. 18 high-speed turnout with the design of gauge widening switch was analyzed by this method, and a better scheme of gauge widening switch was obtained. In this scheme, the maximum value of gauge widening is 15 mm, the maximum value of gauge widening is located in the 30 mm width of the top surface of switch, and the range of gauge widening is 21. 743 m. Train-turnout system dynamics verification and operation practice demonstrate the correctness of the method.
