| Summary: | In order to study the axle load transfer of low-medium speed maglev tractor, the theoretical calculation formula of axle load transfer of maglev tractor was derived, and the axle load transfer results of maglev tractor under quasi-static condition were obtained.. At the same time, through the dynamic model of maglev tractor, the influence rule of different factors on the axle load transfer of maglev tractor was analyzed. By comparing the axle load transfer results obtained by the two methods under ideal working conditions, the difference is comparatively small, it shows that the dynamic method can be used to evaluate the axle load transfer of tractor. The results of axle load transfer based on dynamic method show that: the higher the traction point height is, the lower the adhesion availability of maglev tractor, and this trend is more obvious when the height of traction point is higher than that of couplers; the longitudinal partial load of car body has a great influence on adhesion availability and the best control range is less than or equal to 0.1 m; the arrangement of primary suspension system shall adopt the suspension with symmetrical axle box spring arrangement or the rotating arm positioning suspension system with consistent orientation; The vertical stiffness of suspension system of maglev tractor has little effect on adhesion availability. |
