摘要:
为发展城市跨坐式轨道交通，提高旅客乘坐舒适度，有必要分析轨道梁支座对跨坐式车辆运行平稳性的影响。通过动力学仿真软件建立车桥耦合动力学模型，对轨道梁和支座的车辆动力响应进行仿真计算。利用有限元软件对轨道梁支座耦合振动进行谐响应分析，通过支座刚度和支座跨度与最大车体振动加速度的关系来探究改变支座参数对跨坐式轨道交通耦合振动的影响。研究得出支座参数对跨坐式车辆平稳性的关系曲线，可为指导设计新型轨道梁支座、选择合适的轨道梁支座刚度和支座跨度作参考。
Abstracts:
In order to develop the urban straddle monorail and enhance the passenger ride comfort, it is necessary to analyze the influence of track beam bearing on the stability of straddle monorail. The dynamics simulation software is used to establish a vehicle-bridge coupling model for the simulation of track beam and bearing dynamics response. Then, the finite element software is used to analyze the harmonic response of track beam bearing, and the relationship between bearing stiffness, bearing span and the maximum car body vibration acceleration is explored, to study the influence of bearing parameters change on rail transit coupling vibration. Finally, the relationship curve of bearing parameters to the stability of straddle monorail is obtained, which provides a reference for the design of new type track rail beam bearing, and the proper selection of bearing stiffness and bearing span.
