Problems solved by technology

It is found that when the stiffness of the connecting structure connecting the vibrating table and the fixture is insufficient, the vibration load will be significantly attenuated, and the test piece will still fail to meet the due assessment.
If the size of the connecting structure is increased, the quality of the structure will also increase accordingly, which will cause the connecting structure to consume most of the thrust, resulting in insufficient thrust

Abstract

The invention discloses a double-vibration-table connection structure comprising a connecting panel, connecting bases and a force transferring structure. The connecting panel is provided with a bolt hole for being connected with a test piece. The upper ends of the two connecting bases are both fixedly connected with the lower side surface of the connecting panel. The connecting bases are provided with connecting holes for being connected with the vibration tables. The side surfaces of the two connecting bases are fixedly connected via the force transferring structure. The upper side surface of the force transferring structure is fixedly connected with the lower side surface of the connecting panel. The double-vibration-table connection structure is used as a connection structure for connecting the vibration tables with the test piece by means of the connecting panel, the connecting bases and the force transferring structure, and can apply the capability of the two vibration tables to the same test piece as a mean for transferring vibration excitation, thereby enhancing the loading capacity of a vibration test.

Description

technical field [0001] The invention relates to the field of structural design, in particular to a connection structure of double vibrating tables. Background technique [0002] When carrying out the vibration test of a large mass specimen, the thrust of a single shaking table may be insufficient to carry out the test. In the prior art, a dual-vibration table or multi-vibration table parallel pushing method is adopted to solve this problem. It is found that when the stiffness of the connection structure connecting the vibrating table and the fixture is insufficient, the vibration load will be significantly attenuated, and the test piece will still fail to meet the due assessment. If the size of the connection structure is increased, the quality of the structure will also increase accordingly, which will cause the connection structure to consume most of the thrust, resulting in insufficient thrust. Contents of the invention [0003] The object of the present invention is ...
