And the strength and stiffness of device are not enough, have much room for improvement.
Utility model content
To achieve the above object, the utility model provides following technical scheme：A kind of vibration testing device, including shake table
And retainer ring, the upper surface middle position of the shake table is provided with slide rail, in two slides that are internally provided with of slide rail, and
The upper end of slide is connected with retainer ring, and the retainer ring uses what is used between hydronalium, and retainer ring and slide
It is welding manner connection, the outer surface of the retainer ring is provided with reinforcement, in the croze that is internally provided with of retainer ring, and croze
Be internally provided with bolt, be installed with top board in the upper end of bolt, the outer surface central position of the slide rail is set
There is one of axis, the upper end of slide rail is provided with scale.
As a kind of preferred technical scheme of the utility model, the quantity of the retainer ring is two, and two retainer rings
It is symmetrical in minute surface centered on axis.
As a kind of preferred technical scheme of the utility model, the slide rail uses welding manner company with shake table
Connect.
As a kind of preferred technical scheme of the utility model, the depth of the croze and the complete phase of the length scale of bolt
Deng.
Compared with prior art, the beneficial effects of the utility model are：The vibration testing device, by set reinforcement and
Connected between retainer ring, and retainer ring and slide and between slide rail and shake table using welding manner, make determinand and dress
Connection between putting is more firm, has both met the rigidity and intensity needs of experiment, the intrinsic frequency of device can be improved again, sets
Slide rail and slide, can adjust the distance between two retainer rings according to determinand, make the scope of application of device more extensive；And
Two retainer rings are symmetrical in minute surface centered on axis, and symmetrical structure causes in the overall center of gravity and shake table of device
The heart is overlapped, and vibration test effect is more obvious；Retainer ring uses hydronalium, and magnesium alloy has resistance more more preferable than steel
Damping characteristics, its density also has good solderability also much smaller than steel, and tensile strength is high.
