Study on Relationship between Operating Modal and Shoulder Wear of Straddle-type Monorail Running Wheel Tires

  • 摘要: 跨座式单轨列车在重庆推广运营过程中出现了严重的偏磨损现象并引发一系列安全、环境、运行成本等问题。为探索其偏磨机理及控制方法,采用ABAQUS软件建立了走行轮轮胎的有限元模型,通过轮胎模态试验验证了其建模方法的有效性,并基于行波理论,利用有限元方法计算了考虑走行轮轮胎滚动效应的工作模态,同时探索了走行轮轮胎工作模态与偏磨的关联关系。并根据轮胎结构与模态的内在关系,提出了通过改变轮胎结构参数来控制走行轮轮胎偏磨的控制方法。分析结果表明:通过合理改变0°带束层弹性模量可以降低走行轮一阶扭转前后行波差,有效降低跨座式单轨走行轮的偏磨。
