跨座式单轨车辆动力学性能分析及评价指标研究综述

Review of Research on Dynamic Performance Analysis and Evaluation Index of Straddle Monorail Vehicle

为解决跨座式单轨车辆动力学性能评价指标不全面不系统问题,本文就目前针对跨座式单轨车辆动力学性能及评价指标的研究进行了系统性的总结。由于跨座式单轨列车转向架结构独特,运行、导向机理及轮轨之间的接触关系与传统铁道列车均有不同,导致跨座式单轨车辆的动力学性能及动力学性能评价指标与传统铁道列车差别很大。对此,本文总结了国内外学者对单轨列车动力学性能及车-轨耦合振动响应特性进行的研究,结果表明:目前国内对跨座式单轨车辆动力学性能评价指标的研究通常是采用理论计算和数值模拟相结合的方法,但实测得到的跨座式单轨车辆参数较少,使得研究建立的动力学模型不够准确,这使得国内外都还没有建立一套通用的适用于单轨车辆的动力学性能评价指标。

In order to solve the problem that the evaluation index of straddle monorail vehicle dynamic performance is not comprehensive and systematic,this paper systematically summarizes the current research on straddle monorail ve-hicle dynamic performance and evaluation index.Because of the unique bogie structure of straddle monorail,the run-ning mechanism,steering mechanism and wheel-rail contact relationship are different from those of traditional railway trains,which results in the great difference between straddle Monorail and traditional railway trains in dynamic per-formance and dynamic performance evaluation index.In this regard,this paper summarizes the domestic and foreign scholars'research on the dynamic performance and rail-coupled vibration response characteristics of monorail trains.The results show that:At present,the domestic research on the dynamic performance evaluation index of straddle monorail vehicles usually adopts the method of combining theoretical calculation and numerical simulation.However,the measured parameters of straddle monorail vehicles are few,which makes the dynamic model established by the re-search not accurate enough.As a result,a set of general dynamic performance evaluation index applicable to monorail vehicles has not been established at home and abroad.
