运用ANSYS分析软件建立轨道-桥梁系统模型。分析列车在桥上CRTSⅡ型板式无砟轨道施加制动力情况下,底座与桥面间设置的滑动层和底座与桥梁间设置的固结机构共同作用,以及滑动层单独作用时,不同滑动层摩擦系数对轨道各结构部件受力影响。计算分析结果表明:固结机构是传递制动力的主要结构;当采用合理滑动层摩擦系数时,依靠滑动层和固结机构相互作用,可削弱梁-轨相互作用,使桥梁墩台受力合理。
Establishing Track - Bridge System Model with ANSYS Analysis Software. Analysis of the train on the bridge CRTS Ⅱ plate ballastless track applied braking force, the base and the deck set sliding layer and the base and the bridge between the consolidation mechanism set together, and the sliding layer alone, the different sliding friction Coefficient of stress on the various components of the track impact. The results of calculation and analysis show that the consolidation mechanism is the main structure transmitting the braking force. When the friction coefficient of the sliding layer is reasonable, the interaction between the sliding layer and the consolidation mechanism can weaken the interaction between the beam and the rail, .
