Embodiment 1

[0038] This embodiment provides a decoupling mechanism for two-axis synchronous vibration test, see Figure 3 to Figure 9 , comprising a hinged link 6 and a sliding assembly, the two ends of the hinged link 6 are respectively hinged with the horizontal vibration generator 2 and the workbench 3, the slide assembly is connected with the vertical vibration generator and the workbench 3 respectively, and the hinged link 6 can be Rotate in the vertical direction, the sliding direction of the sliding assembly is parallel to the vibration direction of the horizontal vibration generator 2 .

[0039] In practical applications, when the workbench 3 vibrates vertically under the action of the vertical vibration generator 1 , the hinged link 6 rotates relative to the workbench 3 through the transmission of force, thereby compensating for the vibration in the vertical direction. At the same time, when the table 3 vibrates horizontally under the action of the horizontal vibration generator ...

Embodiment 2

[0056] This embodiment provides a two-axis synchronous vibration test device, see Figure 10 to Figure 11 , including the workbench 3, the horizontal vibration generator 2, the vertical vibration generator 1 and the decoupling mechanism provided in Embodiment 1, the workbench 3, the horizontal vibration generator 2 and the vertical vibration generator 1 are all arranged on the base 12 superior.

[0057] Compared with the prior art, the beneficial effects of the two-axis synchronous vibration test device provided in this embodiment are basically the same as those of the decoupling mechanism provided in Embodiment 1, and will not be repeated here.

Abstract

The invention discloses a decoupling mechanism and a test device for two-axis synchronous vibration test, belongs to the technical field of multi-degree-of-freedom vibration test, and solves the problem that the pin rod is prone to fatigue failure and the safety and reliability of the synchronous vibration test device in the prior art Poor technical issues. The decoupling mechanism used for the two-axis synchronous vibration test of the present invention includes a hinged link and a sliding assembly, the two ends of the hinged link are respectively hinged with the horizontal vibration generator and the worktable, and the sliding assembly is respectively connected with the vertical vibration generator and the working table. The hinged link can be rotated in the vertical direction, and the sliding direction of the sliding assembly is parallel to the vibration direction of the horizontal vibration generator. The invention can be used for two-axis synchronous vibration test.

Description

technical field [0001] The invention relates to a multi-degree-of-freedom vibration test technology, in particular to a decoupling mechanism and a test device for two-axis synchronous vibration tests. Background technique [0002] The two-axis synchronous vibration test device is a mechanical environment test equipment that can perform vibration or shock tests in both vertical and horizontal directions at the same time. Usually, a decoupling mechanism is used to connect the vibration generators in the vertical and horizontal directions with the same working Stations 3 are coupled together. [0003] In the prior art, a two-axis synchronous vibration test device usually includes a vertical vibration generator 1, a horizontal vibration generator 2 and a workbench 3, see Figure 1 to Figure 2 . The vertical vibration generator 1 is coupled with the workbench 3 through a set of slide rail assemblies, so as to compensate the vibration in the horizontal direction. The horizontal ...
