Analysis and Research on the Load of the Box Girder Locomotive Turntable

摘要

The locomotive turntable is an essential device for the steering operation of the railway locomotive.This paper has introduced the structural composition and characteristics of the box girder locomotive turntable,has analyzed its vertical load,horizontal load and torsional load,and has established a mechanical model for the symmetrical structure of the box girder locomotive turntable under the action of positive and negative symmetric vertical loads.Furthermore,it has also demonstrated the safe and reliable structural performance of this type of locomotive turntable on the basis of the practical example of a 35 m box girder locomotive turntable.
