Problems solved by technology

However, due to the limitation of vibration test equipment and technology, the multi-directional vibration environment cannot be realized in the laboratory. It can only be assumed that the vibrations in each direction are independent of each other, and the unidirectional vibration test is carried out sequentially to simulate the multi-directional

Abstract

The invention provides a four-vibration table two-direction joint vibration device. The device comprises a tested piece, a horizontal vibration table, a vertical vibration table, a test clamp which can be loaded bi-directionally, a mechanical decoupling device and a suspension device thereof, a vibration table switching adjustment device and a vibration table support seat. By using the device, horizontal vibration excitation and vertical vibration excitation can be applied to the tested piece at the same time; moreover, the movement in the two directions can be decoupled well by the mechanical decoupling device and the suspension device thereof so that the eccentric moment of the vibration table is avoided; simultaneously, the problem of freely adjusting the positions of the vibration tables in the two directions is also solved by the vibration table switching adjustment device; and therefore, the aim of performing a four-vibration table two-direction joint vibration test is fulfilled.

Description

technical field [0001] The invention relates to vibration test technology, in particular to a combined vibration device with four vibration tables and two directions. Background technique [0002] Vibration test is an important part of product mechanical environment test and reliability test. It is a means of simulating the real use environment of products and an effective method in product design and evaluation. Most of the current vibration tests are carried out on the unidirectional vibration test system, but in fact, the vibration environment of the product during use and transportation is not unidirectional, but multi-directional. have a mutual coupling relationship. However, due to the limitation of vibration test equipment and technology, the multi-directional vibration environment cannot be realized in the laboratory. It can only be assumed that the vibrations in each direction are independent of each other, and the unidirectional vibration test is carried out seque...
