Abstract

The invention provides a transverse stiffness measuring method and device for a railway fastener system, and relates to the technical field of railway detection. The transverse stiffness measuring method for the railway fastener system comprises the following steps: placing a railway assembly between a first force application part and a second force application part which are arranged relatively in order that the first force application part acts on one end, far away from the second force application part, of an iron base plate, and the second force application part acts on one end, far away from the first force application part, of the rail flange of the railway; making the first force application part and the second force application part tightly clamp the railway together; observing thecompression deformation of a rail gauge and shear deformation of a sub-rail elastic base plate. By adopting the transverse stiffness measuring method and device, the technical problem of inaccurate transverse stiffness measuring result of the fastener system in the prior art is solved.

Description

technical field [0001] The invention relates to the technical field of track detection, in particular to a measuring device for the transverse stiffness of a track fastener system and a method for measuring the transverse stiffness of the track fastener system. Background technique [0002] As a rail fastener, the fastener system is one of the important components in the track structure. The lateral stiffness of the fastener system is provided by the compression deformation of the gauge block and the shear deformation of the elastic backing plate under the rail, which plays an important role in the lateral stability of the rail. However, there are currently no clear regulations in China to regulate the lateral stiffness test technology of fastener systems. [0003] The structure of the track assembly is usually as follows figure 1 As shown, the upper side of the iron backing plate 310 is provided with a track, wherein an elastic backing plate 320 is sandwiched between the ...
