A loading test device

Abstract

The invention discloses a load test device. The load test device comprises a base, a deflecting plate, a load distribution beam, a ballast head and a horizontal load plate; one end of the base is provided with a fixed baffle plate, and the other end of the base is provided with a fixed U-shaped horizontal supporting seat; the opening direction of the horizontal supporting seat is away from the baffle plate, a convex part of an opening is arranged on the surface, adjacent to the baffle plate, of the horizontal supporting seat, and a long cylindrical horizontal load head is arranged in the convex part; one end of the deflecting plate is hinged to two wings of the horizontal supporting seat, and the other end of the deflecting plate is hinged to one end of the load distribution beam and can rotate; the other end of the load distribution beam is hinged to the ballast head, the horizontal load plate is arranged below the ballast head, and a joined bearing is arranged between the ballast head and the horizontal load plate. The total load is divided into the ballast and the horizontal plane shearing load by virtue of the load distribution beam according to a lever principle, and the vertical load and the horizontal load can be synchronously applied to a test piece by utilizing one centralized load point, so that the problem that ballast and surface shearing composite load requirement cannot be satisfied by a pressure machine and a universal test machine can be solved.

Description

technical field [0001] The invention relates to the field of structural experiment mechanics, in particular to a loading test device. Background technique [0002] In aviation, navigation, transportation, road and bridge, building, and port engineering structures, the structural parts composed of various materials are complex stress-bearing members, and they are all under complex stress states in various environments for a long time, so these The strength of components under various environments is an important research topic in structural mechanics. Especially in the design of modern engineering structures, it is necessary to study the strength of structures under complex loads and environments. It is urgent to implement complex loads and various environmental conditions on various materials in the laboratory to assess the mechanical strength of materials. , to provide a scientific basis for structural design, and to prepare for the next step of theoretical establishment. ...

Problems solved by technology

[0003] For a long time, it has been very difficult to achieve low cost for this type of material testing

At present, it can be realized by using a two-way hydraulic servo testing machine, but because these equipment are expensive, they have strict requirements on the use environment, and high energy consumption requires high test costs.
