摘要:
为探究自动旅客运输(APM)系统车辆车桥结构性能,找出结构薄弱部位,采用了理论分析、有限元结构分析、极限分析、疲劳分析相结合的方法,研究APM车辆车桥桥壳的应力集中点,对车桥建立走形面和导轨激扰下的受力模型。建立了12种综合工况下车轿的有限元模型,对车桥主要接口V臂和导向框进行相关的有限元分析,并做了台架试验以验证车轿的结构性能。研究表明:12种分析工况基本涵盖了APM车辆运行中所有的路况,是一种可参考的系统分析流程。该研究可为评价车桥的性能指标提供参考依据。
Abstracts:
In order to explore the vehicle\|bridge structural performance of APM system, the weak parts in the structure are detected, theoretical analysis, finite element structural analysis, limit analysis and fatigue analysis are integrated to study the stress concentration points of APM axle housing for the stress model of APM axle housing under the excitation of track surface and guide rail. On this basis, a finite element model of axle under 12 working conditions is established and used to conduct the relevant finite element analysis of V arm and guide frame of the main axle interface. Finally, the vehicle\|bridge structural performance is verified through bench test. The result shows that the 12 discussed working conditions of APM vehicle basically cover all road conditions, and could be taken as a referential system analysis process. This research provides a basis for the evaluation of vehicle\|bridge performance index.
