摘要

单车型低地板有轨电车近年在城市轻轨交通建设中得到广泛应用。旋转止挡作为低地板有轨电车的常用部件，可以限制车体与转向架之间的相对摇头角度范围，其设计方案对车辆通过小半径曲线线路时的运行姿态与动力学性能均具有较大的影响。确定旋转止挡在转向架上的布置方式是对其进行结构与力学性能设计的基础。目前有关旋转止挡的研究较少，并且尚未关注旋转止挡的布置方式及其影响。针对采用不同旋转止挡布置方式的单车型低地板车辆，提出了综合考虑车辆限界与动力学性能要求的旋转止挡间隙优化方法，研究了不同旋转止挡布置方式对有轨电车动力学性能的影响，提出了在保证车辆限界校核结果相当的情况下，可以使车辆动力学性能更优的止挡设计方案。研究结果表明，车辆通过小半径的S形曲线线路时，随着旋转止挡间隙的减小，车辆更加容易满足限界要求，但是车辆的曲线通过安全性有所降低；在设计条件允许的前提下，综合考虑车辆的限界与动力学性能要求，旋转止挡横向布置方式更适用于单车型低地板有轨电车；若受限于设计条件，旋转止挡需要采用纵向布置方式时，可以通过对二系横向止挡进行调整优化，获得动力学性能更优的车辆设计方案。

Abstract

Single-type low-floor trams have been widely used in the construction of urban light rail transit in recent years. As a common component of low-floor trams

the rotation stopping block can limit the relative swing angle range between the car body and the bogie. Its design scheme has a great impact on the movement attitude and dynamic performance of the vehicle when it passes through the small radius curve line. Determining the arrangement of the rotation stopping block on the bogie is the basis for the design of its structure and mechanical properties. At present

there are few studies on the rotation stopping block. The arrangements of the rotation stopping block and its influence have not been paid attention to. In this paper

for single-type low-floor vehicles with different arrangements of rotation stopping block

an optimization method for the rotation stopping block gap was proposed

which comprehensively considered the requirements of vehicle’s gauge and dynamic performance. The influence of different rotation stopping block arrangements on vehicle dynamic performance was studied. A design was proposed which could make the dynamic performance of the vehicle better under the condition of ensuring the same results of the vehicle gauge check. The research results show that when the vehicle passes through the small radius S-shaped curve line

with the reduction of the rotation stopping block gap

it is easier for the vehicle to meet the gauge requirements

but the curve passing safety become worse; With the premise of design conditions permitting

comprehensively considering the requirements of the vehicle’s gauge and dynamic performance

the lateral arrangement of the rotating stops is more suitable for single-type low-floor trams; If the rotation stops need to be arranged longitudinally due to the design conditions

the secondary lateral stop can be adjusted and optimized to obtain an optimized design scheme for the vehicle with better dynamic performance.
