Research on dynamic envelope calculation method of suspended monorail vehicle

悬挂式单轨交通系统在国内尚处于起步阶段,合理地确定车辆动态包络线是保证系统经济性的主要因素之一。文章基于一种自主开发且通过试验验证的悬挂单轨车辆,分析了悬挂式单轨车辆与传统轨道车辆动态包络线构成要素的差异,提出了悬挂式单轨车辆动态包络线计算的总体思路和基本原理,详细说明了动态包络线的构成要素,给出了计算公式,并通过计算与试验结果的对比,验证了计算方法的准确性。相关计算方法可为不同结构悬挂式单轨车辆的动态包络线计算提供参考依据。

For the domestic suspended monorail transit system which is still in its infancy,the reasonable determination of vehicle dynamic envelope is one of the main factors to ensure the system economy.Based on a self-developed and tested suspension monorail vehicle,the differences of the components of the dynamic envelope between suspension monorail vehicle and traditional rail vehicle were analyzed.The general idea and basic principle of the dynamic envelope calculation of suspension monorail vehicle were put forward.The components of the dynamic envelope were listed in detail,and the calculation formula was provided.The accuracy of the calculation method was verified by comparing the calculation results with the experimental results.The relevant calculation methods can provide reference for the calculation of dynamic envelope of suspension monorail vehicles with different structures.
