rail grinding technique and its application in high-speed railway

高速铁路钢轨打磨技术及其应用

Because of the technical monopoly abroad, we do not hold the key technology of rail grinding train.

由于国外技术垄断，目前我国还没有掌握大型钢轨打磨列车的关键技术。

the asymmetric grinding of curved rail head can make the wheel-rail contact point move toward rail centre and apart from rail shoulder. accordingly, the contact stress between the wheel and rail decreases and the rail obligue crack can be eliminated and lightened.

钢轨曲线非对称打磨可以使接触点在轨面上向中心移动，避免接触点靠近轨肩位置，降低轮轨之间的接触应力，从而减轻斜裂纹的发生。

V-shaped rail is a key part on a universal grinding tool.

V型钢导轨是万能工具磨床上的关键零件，为了保证钢导轨的性能要求，在整个加工工序中给予了较多的热处理工序。

the utility model relates to a curved guide rail oscillating plane grinder, belonging to a mechanical device for grinding process.

一种弧形导轨摆动式平面砂轮机，属于磨削加工的机械设备。

based on the period when the rail obligue crack initiates and annual volume of the guang-shen line, it is proposed that the preventive grinding interval of the curved track is about 6 months.

根据线路钢轨表面裂纹出现的时间及通过的年运量情况，建议广深线曲线钢轨预防性打磨周期为6个月。

The guide rail is the 45 # steel, the quenching and tempering, the correct grinding.

导轨为45 # 钢 、 调质, 精磨.

It may decrease fatigue damage causing by rolling contact and side damage on track and prolong rail service life 0.5~ 1 time by means of grinding rail track.

通过对钢轨的修磨可减少由于滚动接触疲劳引起的钢轨损伤，减少钢轨侧面磨损，可延长钢轨的使用寿命0.5~1倍。
