钢轨绝缘接头
优化钢轨绝缘接头的刚度
钢轨绝缘接头对现代轨道交通运营具有重要意义。人们使用钢轨绝缘接头,将钢轨划分成不同的电绝缘分区,以此实现列车定位,从而保证轨道的运行安全性。但是,这种信号技术会对钢轨上部结构的均匀性产生负面影响,导致钢轨绝缘接头成为轨道中最常出问题的地方之一。
问题
刚度的局部差异导致静态力和动态力提高,引发中空、道砟损坏、钢轨开裂、短路等故障,不但会导致区段封锁,还会增加维护成本。
- 道砟磨损
- 空隙
- 信号干扰
- 损坏钢轨和隔振钢轨接头部件
解决方案
为了系统性优化钢轨绝缘接头的刚度,Getzner 专门开发了一种有限元法 (FEM) 计算模型。凭借多年来在钢轨绝缘接头方面取得的专业知识,我们可以按照规定的边缘条件,对轨枕垫和轨下垫板等上部结构中的弹性元件进行精确的调整,达到长期保证较高轨道稳定性的目的。对北美重载铁路进行的轨道检测结果显示,这种优化解决方案效果显著。
- 通过拉长钢轨的弯曲线优化了荷载分布
- 减少了动载荷
- 减少了道砟接触压力
- 延长了捣固间隔,大大降低了维护成本
- 延长了隔振钢轨接头的使用寿命,由此减少了信号干扰
- 提升了轨道利用率
