Embodiment 1

[0038] This embodiment provides a decoupling mechanism for two-axis synchronous vibration test, see Figure 3 to Figure 9 , Including a hinged connecting rod 6 and a sliding component. The two ends of the hinged connecting rod 6 are hinged to the horizontal vibration generator 2 and the worktable 3 respectively. The sliding component is connected to the vertical vibration generator and the worktable 3 respectively. The hinged connecting rod 6 can When rotating 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 worktable 3 vibrates vertically under the action of the vertical vibration generator 1, the hinged link 6 rotates relative to the worktable 3 through force transmission, thereby compensating for the vertical vibration. At the same time, when the worktable 3 is horizontally vibrated under the action of the horizontal vibration gene...

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 the first embodiment, the workbench 3, the horizontal vibration generator 2 and the vertical vibration generator 1 are all set on the base 12 on.

[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 the first embodiment, which will not be repeated here.

Abstract

The invention discloses a decoupling mechanism for two-axis synchronous vibration test and a test device, which belong to the technical field of multi-degree-of-freedom vibration test. The technical problem that the pin rod is prone to fatigue failure and the synchronous vibration test device has poor safety and reliability in the prior art is solved. The decoupling mechanism for two-axis synchronous vibration test of the invention includes an articulated connecting rod and a sliding component. The two ends of the articulated connecting rod are articulated with a horizontal vibration generatorand a worktable respectively. The sliding component is connected with a vertical vibration generator and the worktable. The articulated connecting rod can rotate in the vertical direction. The sliding direction of the sliding component is parallel to the vibration direction of the horizontal vibration generator. The decoupling mechanism and the test device of 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 test. 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 combine the vertical and horizontal vibration generators with the same work Station 3 is 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 worktable 3 through a set of slide rail assemblies to compensate for horizontal vibration. The horizontal vibration generator 2 is coupled with the worktable 3 th...
