The invention discloses a high-speed turnout switch structure and a traction stroke optimization method, a reasonable control method for insufficient displacement is provided based on a high-speed turnout switch rail conversion test, then a switch structure optimization design scheme is researched and provided based on the reasonable control method, and finally matching optimization is performed on the traction stroke of a switch according to the optimized structure. It is ensured that the minimum rim groove and the conversion force meet the requirements, and the deformation coordination performance of the switch rail in the repulsion state is improved. 本发明公开了一种高速道岔转辙器结构及牵引动程优化方法，基于高速道岔尖轨转换试验提出不足位移的合理控制方法，然后在此基础上研究提出转辙器结构优化设计方案，最后针对优化结构对转辙器牵引动程进行匹配优化，确保最小轮缘槽及转换力满足要求并改善尖轨斥离状态变形协调性能。
