This paper preliminarily inquires into the problem of wheel jumping on bridge caused by the irregularities of high—speed railway, and calculates the maximum limited value of the wave heights causing wheel jumping through simulation.

初步探讨了桥上高速铁路不平顺引起的跳轨问题，对跳轨波深的最大限值进行了模拟计算，为高速铁路杜绝桥上跳轨现象的发生提供参考。

In regard to cross the river bridge is now formed pontoon, mechanized bridge / trestle, mechanization railway platform, fabricated truss bridge, building bridges and a motorboat, engineering, floating boxes, fabricated steel products such as road series; in the Special Purpose Vehicle and engineering machinery and mechanization of the main pontoon bridge and set up a dedicated delivery vehicles, loading and unloading trucks and other products from the series; in the steel works has developed a road / rail bridge steel structure, metallurgical equipment, various power transmission towers and microwave towers, steel columns, steel poles and other products.

在渡河桥梁方面，现已形成舟桥、机械化桥/栈桥、机械化铁路站台、装配式桁架桥、架桥汽艇、工程浮箱、装配式公路钢桥等产品系列；在专用汽车和工程机械方面主要有舟桥和机械化桥运载及架设专用车、自装卸车等产品系列；在钢结构工程方面开发了公路/铁路桥梁钢结构、冶金设备、各种输变电塔和微波塔、钢柱、钢质电线杆等产品。

For a long time, China's railway construction for the transport of a large number of high-level technical personnel, scientific and technological progress for China's railway has a major contribution.

长期以来，为我国铁路建设输送了大量高层次的技术人才，为我国铁路科技进步出了重大贡献。

With the improvement of the velocity of the train, more information frequency-shift signal in automatic blocking system is widely used in automatic control system of the block region.

摘要随着铁路提速的发展，多信息移频自动闭塞系统已经广泛应用于铁路区间行车自动指挥系统中。

Widely applied in forming a complete set of the power station equipments of railway, air conditioner train ,telecommunication ,oil field ,mining ,hotel and ships used in army or civilian.

我厂生产的发电机组已广泛用于船舶、铁路建设、铁路空调列车、邮电通信、油田、矿山、宾馆等领域。

A car for use of the train crew; usually the last car on the train .

用于铁路全体工作人员；通常是铁路的最后一班车。

Lots have been used by far as powersupplies of beacon lights,traffic/railway signal lights,traffic caution/marking lights, way nail lights, road lights, aerospace obstacle lights, highway/railway wireless telephone stations, railway points in unmanned guard etc.

目前已在航标灯、交通/铁路信号灯、交通警示/标志灯、道钉、路灯、航空障碍灯、高速公路/铁路无线电话亭、无人值守道班供电等方面大量推广应用。

With the development arise some problems of the wheel/rail performance, the requirement of the train traction for the adhesion of wheel/rail will become more and more strict, and rail corrugation of wheel/rail, rolling contact fatigue and derailment will become more and more serious. The solution to the problems will have direct effects on the railway development.

当前世界铁路正朝着高速和重载的方向发展，随之而来的是列车牵引对轮轨粘着的要求越来越高，而轮轨的波浪形磨耗、滚动接触疲劳、脱轨等轮轨关系问题越来越严重，其解决与否直接影响到铁路的快速发展。

The development tendency of the railway construction in the world today is serving high speed trains and csirrying heavy load. With the development arise some problems of the wheel/rail performance, the requirement of the train traction for the adhesion of wheel/rail will become more and more strict, and rail corrugation of wheel/rail, rolling contact fatigue and derailment will become more and more serious. The solution to the problems will have direct effects on the railway development.
