Dynamics performance of suspension monorail vehicles was tested in virtual prototyping simulation platform to analyze the changing law of line adaptability under multiple operating conditions and the relationship between line adaptability and load conditions (empty and heavy).Test results showed that in linear conditions,the index of stability conformed to the regulations of “Railway vehicles-Specification for evaluation the dynamic performance and accreditation test” (GB/T 5599-1985);The maximum vibration acceleration conformed to the regulations of “the international standard of railway transportation” (UIC-513),which was promulgated by the international union of Railways.These results showed that the standard vehicle had good adaptability in linear conditions.In curve conditions,the maximum guiding force did not exceed the maximum load value and conformed to the safety operation standard,but the composition guiding forces of heavy vehicle was bigger than the safety operation standard,so the vehicle speed should be slow down.%在虚拟样机仿真平台下开展悬挂式单轨车辆动力学性能仿真实验,以分析多工况条件下线路适应性的变化规律,空车和重车两种载荷条件与线路适应性之间的影响关系.结果显示:在直线工况下,平稳性指标满足GB/T 5599-1985《铁道车辆动力学性能评定和实验鉴定规范》的规定,最大振动加速度符合国际联盟颁布的UIC-S13《铁路运输国际标准》规定,表明在直线工况下该制式车辆具有较好的线路适应性.在曲线工况下,导向轮导向力最大值未超过轮胎最大负荷值,符合车辆安全运行标准.但是,在重车运行条件下导向力舍力较大,建议降速运行.
