摘要
道岔是实现列车转线运行的轨道结构,是高速铁路建设中的关键技术之一。为满足俄罗斯莫斯科至喀山高速铁路建设需求,基于高速道岔动力分析理论,设计了适合时速400 km宽轨距高速道岔,主要包括平面线型、直基本轨顶面加工廓形、翼轨垂向抬高结构和弹性均匀的岔区轨道刚度设计。为解决大温差地区高速道岔无缝化难题,研发了适应大伸缩量的新型钩型锁闭机构以及尖轨跟端传力结构型式,既保证了道岔的高平顺性又可有效传递温度力。另外基于有限元原理,建立高速道岔转换计算模型,对转换牵引点间距及其动程进行优化设计,可确保高速道岔可靠锁闭及有效控制长大可动轨件转换不足位移。
Turnout is the track structure to realize the transfer of train to another track,and it is one of the key technologies in the construction of high-speed railway. In order to meet the construction needs of high-speed railway Moscow-Kazan project of Russia,based on the dynamic analysis theory of high-speed turnout,a 400 km/h high-speed turnout with broad gauge is designed,which mainly includes plane alignment,processing profile of straight basic rail top surface,vertical elevation structure of wing rail and track stiffness in the turnout area with uniform elasticity. In order to solve the seamless problem of high-speed turnouts in large temperature difference areas,a new type of hook-type locking mechanism and a force transfer structure at the heel of the switch rail are developed,which not only ensure the high smoothness of the turnout,but also effectively transfer the temperature force. In addition,based on the principle of finite element method,the calculation model of high-speed turnout conversion is established,and the distance between traction points and its movement distance are optimized to ensure the reliable locking of high-speed turnout and effectively control the insufficient displacement of long movable rail parts.
