Abstract

The calculation method of maglev car-body strength has not been unified yet, and the calculation of strength refers mainly to standards of conventional wheel-rail technology, which cannot meet the requirement of maglev technology development. This paper aims mainly at Shanghai high-speed maglev, and refers to other standards to establish the car-body strength analysis and calculation system for Shanghai high-speed maglev. To be specific, normal load conditions and special load conditions are created by linear superposition and combination of single operation conditions. In order to analyze the car-body strength, relevant researches have been carried out in the field of maglev aerodynamics, vehicle system dynamics and finite element strength analysis. In the process of theoretical analysis, actual measurements and test verification have been added. Finally, car-body analysis conditions and load conditions have been created; the car-body strength has been checked; the car-body strength analysis process frame of high-speed maglev has been developed. The results show that the theoretical analysis results are in good agreement with the experimental results, and the working load of maglev vehicle is defined.

上海高速磁悬浮列车车体强度评价方法研究

磁悬浮车体强度计算方法尚未统一，强度计算主要参照常规轮轨技术标准，已不能满足磁悬浮技术发展的要求。本文主要针对上海高速磁悬浮，并参考其他标准建立上海高速磁悬浮车体强度分析计算体系。正常负荷工况和特殊负荷工况是由单一工况的线性叠加组合而成。为了分析车体强度，在磁悬浮空气动力学、车辆系统动力学和有限元强度分析等领域开展了相关研究。在理论分析的过程中，增加了实际测量和试验验证。最后，建立了车体分析条件和荷载条件;车体强度校核;开发了高速磁悬浮车体强度分析流程框架。结果表明，理论分析结果与实验结果吻合较好，确定了磁悬浮列车的工作载荷。
