Study on Partial-Wear-Factor Model Monorail Vehicle Running Wheel

  • 摘要: 走行轮胎偏磨损导致换胎频繁是影响跨座式单轨交通运营成本的重要因素之一. 为快速评估不同单轨车辆设计方案的走行轮胎偏磨损状态,采用因子分析方法分析了影响走行轮偏磨损的10个评价指标,建立了走行轮胎偏磨损因子模型,提出了依据走行轮胎偏磨损因子得分高低评价车辆设计方案优劣的方法. 研究结果发现:影响走行轮胎偏磨损的因子得分排序依次为走行轮纵横向参数因子、导向轮轴距因子、走行轮垂向刚度因子和导向轮垂距因子;建立的走行轮偏磨损因子模型和偏磨损因子得分公式能快速评估不同单轨车辆结构设计方案下的走行轮胎偏磨损状态,从而为跨座式单轨车辆转向架开发设计提供了一种有效的优化设计方法.
