项目摘要
Breakage and excessive displacement of ballast lead to instability and regular maintenance of railways. The project aims to study the fundamental mechanics of ballast aggregates interacting with the apertures of recycled-Rubber Energy Absorbing Grids (REAG). The role of REAG on enhanced track performance by damping the cyclic wheel loading and impact will be quantified via rigorous mathematical methods complementing a computer-based numerical model and validated by laboratory & field data. When placed within the rail substructure REAG will enable reduced ballast movement and breakage while attenuating noise/vibration. The research outputs will facilitate improved rail track design enabling enhanced longevity and reduced cost of maintenance.
道碴破损和位移过大,导致铁路不稳定,需要定期维护。该项目旨在研究道碴集料与再生橡胶吸能格栅(REAG)孔口相互作用的基本力学。通过抑制轮子循环载荷和冲击,REAG在改善轨道性能方面的作用将通过严格的数学方法进行量化,并补充基于计算机的数值模型,并通过实验室和现场数据进行验证。当放置在轨道底座内时,REAG将能够减少道碴移动和破坏,同时减弱噪音/振动。研究成果将有助于改进铁轨设计,从而提高寿命并降低维护成本。
