摘要
在分析跨坐式单轨车辆车体结构特点的基础上,建立了车体结构的有限元模型。结合跨坐式单轨车辆的实际运行状态,确定了垂向弯曲、起动、制动、扭转、吊装等五种工况,并分析了车体结构在各个工况下产生的应力,以判断其静强度是否满足运输要求,为车体的结构优化和疲劳寿命分析提供参考。
Based on the analysis of the structure features of straddled-type monorail vehicle, a finite element model of the car body structure is established by referring to the actual operation of Chongqing monorail vehicles running. The vertical curvature, traction, braking, torsion and loading conditions arc determined and analyzed, in order to judge whether the car body has sufficient strength to meet the demands of transportation, this study provides a scientific basis for the structure optimization and fatigue life analysis.
