Abstract

Abstract

Considering the real irregular geometrical characteristics of ballast and strain rate effect and failure behavior of material, finite element models of ballast impact on equipment cabin bottom plate of high-speed trains was established, and the deflection history response of transverse and longitudinal centerline nodes of equipment cabin front face sheet was analyzed. The history evolution regulation of contact force between equipment cabin bottom plate and ballast was investigated, and the effects of impact velocity, impact angle and ballast shape on impact response and damage behavior of equipment cabin bottom plate were also discussed, the failure mode and damage morphology characteristics of equipment cabin bottom plate under different conditions were analyzed, the relationship between the maximum transient deformation displacement as well as pit depth and impact velocity were quantified. The results show that, under the same impact condition, the maximum transient deformation displacement and pit depth of equipment cabin bottom plate increase with the increase of impact velocity and impact angle separately; the shape and size of maximum deformation zone of front face sheet of equipment cabin, and the area and distribution characteristics of front face sheet damage failure region are closely related to ballast shapes, the most severe damage failure occurs in ellipsoid ballast conditions; equipment cabin bottom plate under different impact conditions shows different degrees of ductile damage, and the larger ballast mass and impact velocity conditions also show tensile tear damage or even slight punching plug phenomenon.
