Abstract

The invention discloses a multi-span simply-supported boundary condition test device, relates to a supporting test device and aims to solve problems that the support position of an existing beam and plate simple support boundary condition experiment device cannot be adjusted, and that beams (plates) with different sizes cannot be simply supported in the prior art. The device comprises a pluralityof bottom plates, a cross beam and a plurality of supporting assemblies, wherein the bottom plates are arranged side by side along a straight line, one supporting assembly is installed on each bottomplate, and a test beam is horizontally installed on the supporting assemblies. The invention belongs to the technical field of mechanical test devices. The device is advantaged in that simple supporting of beams (plates) with different widths and lengths can be achieved, cost is low, universality is high, and the scientific research expenditure of related experiments can be saved.

Description

technical field [0001] The invention relates to a mechanical test support device, in particular to a multi-span simply supported boundary condition test device, which belongs to the technical field of mechanical test devices. Background technique [0002] In scientific research and engineering practice, in addition to using theoretical analysis methods, the research on the static and dynamic characteristics of specific beam and slab structures often requires experimental verification to ensure the accuracy and reliability of the analyzed structure. Whether the experimental conditions are reasonable and whether the theoretical analysis assumptions are satisfied greatly affect the accuracy of the experimental results. The support position of the existing experimental devices for simply supported boundary conditions of beams and plates cannot be adjusted, and simply supported beams (slabs) of different sizes cannot be realized, which affects the efficiency of experimental resea...
