Abstract

The invention belongs to the technical field of mechanical environmental test, particularly relates to a triaxial mechanical decoupling device and a vibration testing system, and provides a device for connecting a triaxial simultaneous excitation work bench and a testing system. The triaxial mechanical decoupling device is characterized by comprising a work bench (1) and spherical hydrostatic bearings (4), the work bench (1) is in the shape of a metal plate, two mutually perpendicular mounting faces which are perpendicular to the upper end face and the lower end face of the work bench are arranged on the lateral side of the work bench (1), the spherical hydrostatic bearings (4) are respectively mounted on the lower end face (3) of the work bench, an X-directional side (7) of the work bench and a Y-directional side (2) of the work bench, and the other side of each spherical hydrostatic bearing (4) is connected with a vibration generator. Triaxial composite vibration testing of a workpiece can be achieved by using the corresponding triaxial work bench and the spherical hydrostatic bearings. By means of the triaxial mechanical decoupling device, the workbench can move only in the Z-direction, the X-direction or the Y-direction, so that triaxial translation of the work bench is realized.

Description

technical field

[0001] The invention belongs to the technical field of mechanical environmental tests, and in particular relates to a three-axis mechanical decoupling device and a vibration test system. Background technique

[0002] In the real environment, the natural vibration environment of most products is a multi-directional, multi-degree-of-freedom compound vibration environment. The existing uniaxial vibrator cannot realize the vibration simulation of three axes at the same time. Simultaneous vibration of the three axes requires the installation of single-degree-of-freedom exciters in the three axes, and the existing mechanical decoupling device connecting the working platform and the single-degree-of-freedom exciter easily leads to three single-degree-of-freedom vibrations There is a strong motion cross-coupling between the vibration table itself and the degree of freedom of motion in the non-force transmission direction to produce lateral limit constraints.
