Summary of the invention
The utility model purpose provides a kind of nothing ground fundamental mode three-dimensional electric vibration testing bench, to overcome fabricating yard and the condition harshness that the three-dimensional of foundation structure electric vibration testing bench is arranged in the prior art, the defective that installation cost is high.
For achieving the above object, the technical solution adopted in the utility model is: a kind of nothing ground fundamental mode three-dimensional electric vibration testing bench, the gudgeon and the proving installation of involving vibrations generator, horizontal sliding table, fuel tank, static pressure oil supply loop, pedestal, band vibration damper, pedestal adopts horizontal type structure, the vibration generator is erected at a side of pedestal by gudgeon, and is in extreme lower position; Horizontal sliding table is located in the opposite side of pedestal, and be in extreme lower position, fuel tank is located at the horizontal sliding table below and is fixed on the pedestal, and fuel tank forms the static pressure oil supply loop by the floating surface of fluid pressure line and horizontal sliding table, and supporting surface adopts whole facade or many facades supporting construction at the bottom of the pedestal.
In the technique scheme, described " pedestal employing horizontal type structure " is meant that center of gravity is low as far as possible on the structural design of pedestal, and has bigger contact area with ground.Described " proving installation " comprises sensor, testing meter and instrument and circuit etc.
In the technique scheme, in order to produce bigger stiction, can place mat one deck vibration isolation rubber between pedestal bottom surface and the ground.
In the technique scheme, described " whole facade " is meant that the whole bottom surface with pedestal is designed to a plane, with the supporting surface of this plane as pedestal.
In the technique scheme, described " many facades supporting construction " is meant that the pedestal bottom surface is designed to the situation that the polylith plane is supported simultaneously, specifically comprises following multiple version (can also comprise other variation):
1, is arranged in parallel by at least two facades and constitutes, referring to accompanying drawing 4;
2, constitute by a shaped as frame facade, referring to accompanying drawing 5;
3, constitute by at least two shaped as frame facade snares layouts;
4, by the opposed formation of " Contraband " shape facade, referring to accompanying drawing 6;
5, constitute by " day " font facade;
6, constitute by " order " font facade;
7, constitute by bar shaped and " Contraband " shape, referring to accompanying drawing 7.
In the technique scheme, after fuel tank is built in pedestal, the operating surface of fuel tank and static pressure oil supply loop can be located on the side of pedestal for easy to operate.
Technique scheme is concentrated following several the measures of having taked on the basis of existing technology:
1, original external fuel tank is changed into built-in Oiltank structure, volume has not only been dwindled in its effect, the more important thing is and to effectively utilize fuel tank weight, make vibration table and ground produce bigger stiction, played positive role preventing that pedestal from moving.
2, the multi-column supporting structural of original pedestal bottom surface is transformed into whole facade or many facades supporting construction simultaneously, what strengthened pedestal greatly does the ability of toppling and stability.
3, with the design of centre of gravity of whole equipment to extreme lower position, further improved the stability of whole equipment.
4, each ingredient of equipment is linked to be integral body, and adopts left and right sides arrangement, and this is very favourable to whole equipment gravity balance.
The utility model has produced very positive effect after with above measures integrated use in a word; be centering, little other three-dimensional electric vibration testing bench of level; the original foundation structure design that has can be changed over no foundation structure design fully; this technical conceive has been broken through the conventional mounting pattern of three-dimensional electric vibration testing bench for a long time, has technical progress significantly and creativeness.
The utility model compared with prior art has following advantage and effect:
1, improves the stability of three-dimensional electric vibration testing bench self greatly, also improved every test index simultaneously.
2, improved stiction, making testing table need not ground can install and use, so not only easy for installation, and has reduced installation cost.
3, reduce the floor area of testing table, testing table can be installed in any floor simultaneously, greatly reduced fabricating yard condition and requirement.
