Abstract

The invention relates to a cyclic loading tamping teststand for indoor crushed stone ballast track beds, and belongs to the technical field of railway engineering blast track bed detection. The cyclic loading tamping teststand comprises a cyclic loading apparatus, a tamping apparatus, a movable loading vehicle, a loading hydraulic system, a ballast track bed, a track panel, a ballast box I, a power supply, a ballast box II, a groundwork and ground pit system, a track bed detection system, a system damping apparatus and a vehicle walking track. The cyclic loading tamping teststand performs cyclic loading tests to simulate loading effect of a train on a ballast track bed and simulate tamping operation of the crushed stone ballast track bed, performs test analysis and test research on track bed compactness. The cyclic loading tamping teststand is capable of simulating operation of a train with the shaft weight of 0.5-35 ton and the speed per hour of 40-350 Km / h on a ballast track, performing real-time testing and monitoring and acquiring data. During tamping simulation operation, the cyclic loading tamping teststand is capable of realizing the tamping frequency variation scope of 15 Hz-60 Hz and realizing multi-station operation with high testing precision and high testing efficiency, satisfies indoor repeatability test demands, and is strong in anti-interference capability.

Description

technical field [0001] The invention relates to an indoor bulk ballasted ballast bed cyclic loading tamping test bench, in particular to occasions such as railway bulk ballasted bed test detection and tamping operation evaluation, which is used for studying the physical and mechanical properties of the bulk ballast bed and performing bulk ballast bed testing. The utility model relates to special test equipment for ballasted ballast bed cyclic loading test and tamping test analysis test, which belongs to the technical field of railway engineering track bed detection. Background technique [0002] Bulk ballast bed is an important part of high-speed railway track structure. The internal mechanism of geometric deformation degradation of high-speed bulk ballast bed has become a key problem to be solved urgently. The discrete dynamic characteristics of bulk ballast bed determine its basic physical and mechanical properties, which is an important factor affecting the bearing capac...
