摘要
确定现代有轨电车的不平顺管理值是其轨道和基础结构设计的前提条件。以上海松江有轨电车为例,运用车辆-轨道耦合动力学理论,建立有轨电车多刚体模型,以轨道的高低、水平和方向不平顺为评价指标,对轨道不平顺的幅值及其敏感波长进行分析。结果表明,运行速度为70km/h的松江有轨电车其轨道高低、水平和方向不平顺敏感波长均为10~20m,并据此确定了有轨电车轨道动态的不平顺管理建议值。
The management value of irregularities of modern trams is a precondition for the design of track and foundation structure. Taking the tram in Shanghai Songjiang as an example, it uses vehicle-track coupling dynamics theory to build the rigid body model of tram, analyzes the sensitive wavelength and amplitude of track irregularities based on the track height, horizontal and direction irregularities. The research shows that the track wavelength, horizontal and directional irregularities of 70km/h trams in Songjiang are all 10~20m, and on this basis, the recommended value of tram track irregularity management is determined.
