The main aim of this research is to improve the long-term behaviour and life cycle cost of railway switches & crossings and transitions. This work will focus on analysing the effects of non-homogeneous track support stiffness on the vehicle-track system and developing solutions to optimise its performance. To do so, it is necessary to understand the main degradation mechanisms on the switch and crossing panels. A numerical model of the train and a complete turnout will be developed, that accurately considers the train-track interaction and allows to predict these degradation mechanisms and study different solutions to improve the long-term behaviour and life cycle costs.

本研究的主要目的是改善铁路道岔、道口和过渡的长期性能和生命周期成本。这项工作的重点是分析非均匀轨道支撑刚度对车辆轨道系统的影响，并制定解决方案以优化其性能。要做到这一点，有必要了解开关和交叉面板上的主要退化机制。将开发列车和完整道岔的数值模型，该模型准确考虑列车-轨道相互作用，并允许预测这些退化机制，研究不同的解决方案，以改善长期行为和生命周期成本。
