悬挂式单轨列车挡车器结构设计

Structural Design of Buffer Stop Applied in the Suspended Monorail Train

悬挂式单轨交通采用悬挂式构造,结构形式区别于传统轨道交通,且国内尚无成熟的运营线路,关于悬挂式单轨列车挡车器的研究较少。参考城市轨道交通,研究和总结了悬挂式单轨挡车器的设计应遵从足够的制动能力、合理的缓冲吸振、易于安装维护、美观性好的原则,主要设计参数包括撞击荷载、撞击速度、制动减速度、线路预留安装长度、车体撞击点等。基于功能需求,研究提出了多种新型挡车器,适用于不同运营工况下的悬挂式单轨交通。研究成果可为悬挂式单轨列车挡车器的结构设计及标准规范的制定提供参考。

The suspended monorail transit adopts a different suspension structure from the traditional rail transit.There has been no mature operation line in China and little research has been dedicated to the suspension monorail train buffer stop.Referring to urban rail transit,this article studies and summarizes such design principles of the monorail train buffer stop as sufficient braking capacity,reasonable buffer and vibration absorption,easy installation and maintenance,and appealing outlook.The main design parameters include impact load,impact speed,brake deceleration,reserved installation length of the track,vehicle body impact point,etc.Based on the functional requirements,a variety of new car stops are proposed,which are suitable for suspension monorail transit under different operating conditions.The research results can provide references for the structural design and standard specifications of buffer stop applied in the suspended monorail train.
