In rails, which are used in modern

In rails, which are used in modern high-speed trains, bespecial requirements are placed on the straightness. Straightness during operation canlead to the excitation of vertical vibrations that harm vehicle and superstructure,increase the maintenance costs and not least affect the driving comfort.The necessary to achieve the desired straightness roll straightening process are inevitableintroduced internal stresses which affect the fracture resistance of the railsand thus are of great importance for the use behavior of the rails.
When NMH Stahlwerke GmbH attempts to improve the straightening process werethe aims of minimizing the harmful residual stresses while maintaining the requiredStraightness performed. It could be shown that by suitable measuresthe longitudinal stresses are reduced in the rail head and foot by about 40%can.

在 rails，用于现代高速火车，bespecial 要求放置在直线度。在操作精细化的损害车辆和上层建筑的竖向振动激励下的直线度增加维护成本和不至少影响驾驶的舒适性。需达到所需的直线度辊矫直过程的是 inevitableintroduced 影响抗折强度 railsand 的内部应力因而是非常重要的 rails 的使用行为。当卫生 Stahlwerke GmbH 试图改善矫直过程之间相距甚目的的同时保持 requiredStraightness 执行减少有害的残余应力。可显示适合诸如此类纵向应力减少在轨头脚约 40%可以。

在Rails中使用的现代高速列车，特别要求放在直线度。直线度在操作过程中导致的垂直振动危害车辆和上部结构的激励，增加维修成本和不影响行车的舒适性，达到了预期的直线度辊矫直过程中必要的inevitableintroduced影响重要的断裂阻力从而具有重要意义的钢轨内部应力的使用行为。当NMH Stahlwerke GmbH试图提高矫直过程是通过最小化有害残余应力在维持requiredstraightness进行。它可以表明，通过合适的两纵向应力在轨头和大约40%英尺降低。
