- In order to analyze the impact of height adjustment for Vossloh300 fasteners on the rail lateral displacement and the stress of sleeper bumping shoulder, the paper construct the mechanic model and finite element model, the rail lateral displacement and the stress of the sleeper bumping shoulder were calculated in terms of different adjustment heights. The results show that under the same load, the rail lateral displacement increases with the increasing fastener height adjustment, but the increment is small. The expansion of the rail lateral displacement results in rail lateral bending while has little influence on rail torsion. In addition, under the load, maximum principle stress of the joint between sleeper bumping shoulder and rail ditch. With the increasing of the adjust height, maximum principle stress of the sleeper bumping shoulder decreases.
