Abstract

The present invention relates to a multi-functional vibration device comprising rotating frame assemblies disposed vertically at the left and right parts, a mounting plate assembly disposed horizontally between the rotating frame assemblies, and a test bed interface assembly located at the bottoms of the rotating frame assemblies. The two ends of the mounting plate assembly connected to the rotating frame assemblies are respectively provided with a rotating shaft at the central part and limiting bosses at the end parts. The multi-functional vibration device provided by the invention can realize the vibration requirements of the test product in three directions, and can also realize the vibration test of multiple products at the same time, satisfy the multiple requirements of the reliability enhancement test on the vibration direction of the product, and realize a multi-purpose device. The test time and the test cost are saved.

Description

technical field [0001] The invention relates to a vibration test device, in particular to a multifunctional vibration device capable of realizing simultaneous vibration in three directions and multiple products. Background technique [0002] In the environmental test, the vibration test is one of the five environmental tests that must be done. In particular, the reliability enhancement test requires vibration tests in three directions of the product. The traditional vibration test bench can only provide vibration positioning in one direction, and three different fixtures need to be designed to meet the vibration requirements in three directions. When there are many test products, it will bring more devices and increase the cost. Moreover, it is necessary to replace the devices when performing vibration tests in different directions, which is time-consuming. Therefore, it is necessary to develop a test device that can meet the vibration requirements in multiple directions. ...
