The invention relates to a visual high-speed
train roadbed granule vibration-
subsidence recapitulation
model test system, which comprises a
model test box, a distributive high-frequency loading device, a roadbed nonuniform deformation regulation device, a
visual monitoring device and a work
station, wherein the
model test box is used for simulating a
ballast track roadbed form and a ballastless track roadbed form; the distributive high-frequency loading device is used for simulating dynamic load generated in the advancing process of a high-speed
train, and regulating the waveform, the amplitude value, the frequency and the
phase difference of the dynamic load; the roadbed nonuniform deformation regulation device is used for quantificationally controlling and simulating the roadbed longitudinal nonuniform deformation; the
visual monitoring device comprises a high-speed camera and a
light source in opposite arrangement with the model test box, and is used for shooting a roadbed longitudinal cross section image in the model test box; the work
station is connected with the distributive high-frequency loading device, the roadbed nonuniform deformation regulation device, the high-speed camera and the
light source, and is used for realizing the
experiment control and obtaining the roadbed longitudinal cross section image for analysis and
processing. Compared with the prior art, the visual high-speed
train roadbed granule vibration-
subsidence recapitulation model test
system has the advantages of precise
simulation, intuition, accuracy and the like.
