铰接系统刚度阻尼对虚拟轨道列车横向稳定性的影响研究
Study on the Influence of Stiffness and Damping of Articulation System on the Lateral Stability of Virtual Rail Trains
摘要
Abstract
Virtual rail trains,as a new type of rail transit system that has emerged in recent years,integrate the advantages of medium capacity rail transit and rapid transit,and have become an important part of urban public transportation systems.However,due to its high degree of structural freedom,there is a hidden danger of lateral instability such as sway,folding,and tail swinging similar to that of a semi-trailer during actual operation.The influence of stiffness and damping of the articulated system on the stability of vehicle straight-line driving and curve passing through are studied through dynamic simulation.The research results indicate that under straight driving conditions,increasing the hinge stiffness to 5×104 N/m and damping to 107 N·s/m can achieve a zero damping vehicle speed of 81 km/h.Under high-speed lane changing conditions,increasing the hinge stiffness reduces the amplification factor of the middle car rear by 29.9%and the amplification factor of the rear car rear by 31.6%.During the process of passing through a large radius curve,increasing the hinge stiffness can also reduce the maximum rear axle trajectory offset by 21.96%and the steady-state value by 22.18%.During the process of passing through small curves,increasing the hinge stiffness does not increase the trajectory deviation or tire lateral force,therefore it does not affect the vehicle's curve passing performance.关键词
