摘　　要：列车过岔时轮对横移量的大小是道岔通过性能的重要参数,也是影响道岔通过速度的关键因素之一。通过现场实测采集道岔型面数据,根据轮轨动力学理论利用仿真软件建立列车-道岔动力学仿真模型,对高速列车通过客运专线18号道岔时产生的轮轨横移量进行了仿真分析。仿真结果表明列车过岔时在转辙区和辙叉区的横移量较大,且转辙区横移量大于辙叉区。轮对横移量随列车过岔速度的提高增大,实测横移量比仿真偏移量大些,最大实测横移量发生在10号岔枕处,平均值为8.40 mm。Lateral displacement of wheelset is an important factor of turnout passing performance, which affects the passing speed to a great degree. In this paper, the data of turnout profile is collected from field test, according to wheel/rail dynamic theory, a vehicle-turnout dynamics simulation model is established by using the multi - body dy-namics simulation, which simulates the lateral displacement of wheelset when a high - speed train passes through the No. 18 turnout on this passenger dedicated line. The analyt-ic results show that the lateral displacement in switch area is larger than that in frog area, and is smallest in connecting area, meanwhile the lateral displacement will become lar-ger when the speed of vehicle increases. The largest lateral displacement from field test occurs near the No. 10 switch sleeper, and the average lateral displacement is 8.40 mm.
