摘要

研究目的:对重庆市跨座式单轨交通系统进行动载试验，检验跨座式单轨交通系统的实际动力性能。

研究方法:通过对不同车速下重庆市跨座式单轨交通系统动力性能的检测试验，研究跨座式单轨交通PG 轨道梁的动力特性及其动力响应，并对单轨车辆乘坐舒适性进行测试与分析。

研究结果:PG轨道梁结构实测动力特性与理论计算结果基本相符。

研究结论:轨道梁结构具有良好的竖向刚度和结构强度;单轨车辆以不同速度通过桥梁时，试验梁横向基频、横向加速度等横向振动性能与铁路桥梁检定规范要求有一定差异;单轨车辆在桥上运行时对轨道梁结构有一定的冲击作用;参照IS02631,UIG513和GB5595一85评价标准，对单轨车辆乘坐舒适性采用舒适度和平稳性2个指标进行的测试分析表明，运行车辆具有良好的乘车舒适性。

Abstract

Research purposes: In order to inspect the actual dynamic responses of Chongqing straddle-type monorail transportation system, dynamic loading tests were carried out.

Research methods: Through dynamic performance test on Chongqing straddle-type monorail transporation system under different speed, the dynamic characteristics and responses of PC rail beams were studied, and at the same time the comfort of passengers of monorail vehicles was also tested and analysed.

Research results: The dynamic characteristics tested of PC rail beams matched well with theoretical calculation.
