Research on Car-Body Strength Evaluation Method of Shanghai High-Speed Maglev

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.
