通过ＤＫ２０型地铁车辆轮重分布试验，分析了目前地铁车辆轮重分布不均的问题。建立地铁车轮轮重分布的简化力学结构分析模型，采用有限元和经典力学两种方法，分别对其进行了计算分析及理论推导，找出了地铁车辆轮重分布规律和解决轮重分布不均问题的措施
Through the wheel weight distribution test of DK20 metro vehicle, the problem of uneven distribution of wheel weight in metro vehicles is analyzed. The metro wheel wheel redistribution simplified mechanics structural analysis model is established. The finite element method and the classical mechanics method are respectively used to calculate and analyze the theory and deduce the theory respectively. The distribution of the wheel weight of the metro vehicle is found out and the uneven distribution of the wheel weight is solved Problem of the measure
