Combined structural test loading device

Abstract

The invention relates to a combined structural test loading device and belongs to the field of structural test technologies. The combined structural test loading device comprises a foundation 1, four racks 2, a lower cross beam 3, a loading oil cylinder 4, an upper cross beam 5, an upper frame 6, a lock bolt 7, a secondary cross beam 9, an actuator 10, a base 11 and a hydraulic floating supporting platform 12, wherein the four racks 2 are mounted at the upper part of the foundation 1 and are integrally connected through the upper frame 6 at the upper end; the upper cross beam 5, the loading oil cylinder 4 and the lower cross beam 3 are mounted at the lower part of the upper frame 6; the secondary cross beam 9 is mounted below the lower cross beam 3 and is connected with the base 11 through the actuator 10; a test piece placement position for placing a clamping test piece 8 is arranged between the secondary cross beam 9 and the base 11; the loading oil cylinder 4 and the actuator 10 jointly apply load on the clamp test piece 8. According to the invention, a secondary loading device is additionally arranged on the existing large-scale structural testing machine, an original structural testing machine can be transformed according to the actual demand, and the secondary loading device can be used independently.

Description

Technical field: [0001] The invention relates to a combined structure test loading device, which is suitable for upgrading and reforming existing large-scale structure test machines, and belongs to the technical field of structure experiments. Background technique: [0002] Large-scale structural testing machine is one of the important development directions of structural experimental technology in recent years, and it is an important means to carry out research on the failure mechanism of full-scale components and serve engineering design. Although large-scale multifunctional structural testing machines cost a lot of money, in order to adapt to the rapid development of modern science and technology, countries have begun to develop large-scale structural testing machines with large tonnage and large table to meet the increasing requirements for the output load of the loading system. So far, except for the 10,000-ton test machines built by the University of Stuttgart in Germa...

AI Technical Summary

Problems solved by technology

So far, except for the 10,000-ton test machines built by the University of Stuttgart in Germany and the Central Institute of Technology in Japan, the large-scale structure test machines that have been built are generally several thousand tons, which cannot meet the test requirements of large structures.

To improve the loading capacity of the equipment, it is possible to rebuild the equipment or replace the loading cylinder of the existing equipment, but there are problems such as high equipment cost, difficulty in replacing the loading cylinder, and serious waste of existing resources.
