Abstract

The invention belongs to the technical field of mechanical environmental tests, and in particular relates to an automatic return device used in a triaxial vibrating system. The device comprises an upper mounting flange, a lower mounting flange, hexagonal jack screws and elastic recovery devices, wherein the head part and the tail part of each elastic recovery device are inserted into mounting holes corresponding to the upper mounting flange and the lower mounting flange respectively; and the elastic recovery devices are fixed through the hexagonal jack screws in fixing holes outside the flange walls of the mounting holes. The automatic return device used in the triaxial vibrating system has the characteristics of rapid response, reliable running, lower machining cost, high anti-environment interference capacity and the like, can bring convenience to manual adjustment and is convenient to operate and easy to maintain.

Description

technical field [0001] The invention belongs to the technical field of mechanical environment tests, and in particular relates to an automatic return device used in a three-axis vibration system. Background technique [0002] In the real environment, the vibration environment of most products is multi-directional, multi-degree-of-freedom compound vibration. However, due to the limitation of test equipment and means, multi-axis simultaneous vibration test can only be simulated by uniaxial vibration test in each direction separately. With the continuous improvement of product precision, reliability requirements and test efficiency, the one-way vibration test can no longer meet the test requirements of the vibration environment. [0003] Such as figure 1 and 2 As shown: the three-axis vibration system is composed of three unidirectional vibration tables, such as electro-hydraulic, electric and pneumatic, etc., which excite the same working platform in three mutually perpendic...
