Elevated steel spring floating plate experimental simulation platform

Abstract

The invention relates to the technical field of rail transit, and discloses an elevated steel spring floating slab experimental simulation platform, comprising: a bottom plate, the top of which is provided with two rows of first positioning holes along the length direction of the bottom plate; Bottom plate connection; steel spring assembly, which includes a simulated steel spring and a first positioning piece and a second positioning piece respectively connected to two ends of the simulated steel spring, the first positioning piece cooperates with the first positioning hole; and a top plate assembly, which includes The simulated floating plate and the steel plate detachably connected with the simulated floating plate, the bottom of the steel plate is provided with two rows of second positioning holes along the length direction of the bottom plate, the second positioning holes cooperate with the second positioning piece, and the two rows of first positioning holes The spacing between them and the transverse spacing between the two rows of second positioning holes are equal to the transverse arrangement spacing of the simulated steel springs. The platform can quickly change the parameters of the floating plate, steel spring stiffness and steel spring spacing, which is convenient for the rapid parametric experiment of the elevated steel spring floating plate in the laboratory.

Description

technical field [0001] The invention relates to the technical field of rail transit, in particular to an elevated steel spring floating slab experimental simulation platform. Background technique [0002] In elevated urban rail transit, the beam structure forms are complex and diverse. For different beam structures, the vibration and noise reduction performance of the same steel spring floating slab on the structure and the surrounding environment is different. The prefabricated short slab assembled floating ballast bed is adopted It is also possible that some more complex influencing factors will be added to the traditional integral casting floating slab track bed. Therefore, it is necessary to develop different steel spring floating slabs and targeted optimization measures for different beam structures in order to exert its maximum function. The development trend of spring floating plate in-depth research and development. [0003] In order to conduct in-depth research and...

Problems solved by technology

However, in actual engineering, it is difficult to find site conditions that can meet the user's research requirements. Therefore, it is unrealistic to conduct field tests for different design parameters of steel spring floating plates, and the cost of manpower and material resources is also huge.
