The present invention is described below in conjunction with the accompanying drawings and with reference to specific embodiment.
The vibration test fixture 100 of the embodiment of the present invention is described with reference to Fig. 1 and Fig. 2 first.
As depicted in figs. 1 and 2, the vibration test fixture 100 of the embodiment of the present invention can include the first base cross members 1, the
Parts are being carried out vibration examination by two base cross members 2, the first top longitudinal beam 3, the second top longitudinal beam 4 and multiple bolts 5
When testing, parts to be tested can be fixed on shake table 200 by vibration test fixture 100, shake table 200 can vibrate
To test performance when parts to be tested vibrate.
As depicted in figs. 1 and 2, the first base cross members 1 and the second base cross members 2 can be fixed on shake table 200, and first
Base cross members 1 can in X direction be arranged in parallel with the second base cross members 2, and the first base cross members 1 and the second base cross members 2 it
Between relative distance it is adjustable (that is, in the Y direction apart from adjustable).
Specifically, can be with arranged for interval multiple threaded locating hole along Y-direction on shake table 200, Y-direction can be with X-direction
Vertically, after the distance between the first base cross members 1 and the second base cross members 2 are adjusted to correct position, can be by the first bottom
Crossbeam 1 wears threaded locating hole and is connected with shake table 200 by bolt respectively with the second base cross members 2.Thus, it is possible to realize
