In working environment like that, comprise the product of vibration and centrifugal factor simultaneously, vibration, centrifugal comprehensive effect can comprise all effects that these cause separately, and vibration, centrifugal integrated environment may influence each other, be created in the absent variable comprehensive effect of any single environment.Therefore be directed to this series products, thereby want working environment that is virtually reality like reality to greatest extent and reach good test effect, just must vibrate simultaneously, centrifugal test, otherwise single vibration test or centrifugal test will be ignored some integrated environment stress, cannot reach comprehensive test effect.
In currently available technology, to the test of vibration be mainly by all kinds of electronic, mechanical, hydraulic vibration gens to test specimen impose sine, at random, the mode of vibration such as impact, vibratory impulse with imitation specimen in practical service environment, thus the vibration test of testing exemplar completed; Mainly by all kinds of high speed rotation equipment, test exemplar to be imposed to constant acceleration to be used for examining product whether to meet the test loading procedure with repeatability and the concrete operations test method of requirements to centrifugal test.But no matter be shaking table or hydro-extractor, single vibration or centrifugal test all can only be provided, cannot vibrate and centrifugal composite testing simultaneously, there is no at present that a kind of device can vibrate, the composite testing of centrifugal test.
Summary of the invention
The utility model object is to provide a kind of vibration, centrifugal compound testing equipment, can vibrate and centrifugal compound test, thereby reach comprehensive test effect.
For achieving the above object, the technical solution adopted in the utility model is: a kind of vibration, centrifugal compound testing equipment, comprise a hydro-extractor and an air-cooled electric vibration table;
Described hydro-extractor comprises a pedestal, and on this pedestal, along continuous straight runs arranges a pivoted arm, and the relative pedestal in pivoted arm middle part is rotationally connected around vertical line direction; On described pivoted arm, effect has drive unit, drives pivoted arm to rotate relative to pedestal with drive unit; The two ends of described pivoted arm all stretch out, and counterbalance weight, as load end, is established as balance end on its other end in its one end, and the center of rotation place of pivoted arm is provided with brush;
Described air-cooled electric vibration table involving vibrations platform main frame and blower fan; Described shaking table main frame comprises stage body and is located at the moving-coil in stage body, and described shaking table main frame is located on the load end of pivoted arm, and the direction of vibration along continuous straight runs of its moving-coil; Described blower fan is located on the stage casing of pivoted arm, and blower fan is connected with shaking table main frame by hard pipeline; And described shaking table main frame connects brush through the wire being fixed on pivoted arm, switches on power and input/output control signal through brush with this.
Related content in technique scheme is explained as follows:
In such scheme, described " air-cooled electric vibration table " refers to and adopts the blower fan cooling electric vibration table that ventilates.
Design concept of the present utility model and advantage are as follows:
The utility model has carried out Integration Design to hydro-extractor and air-cooled electric vibration table, shaking table main frame is located to the load end of hydro-extractor, when test, on the moving-coil table top of shaking table main frame, fix test specimen, make the not only vibrated power of test specimen but also be subject to centrifugal action, reached vibrate, the object of centrifugal compound test, filled up the blank in this field.And the blower fan of the utility model electric vibration table is arranged on the stage casing of hydro-extractor pivoted arm, so that the centrifugal force that blower fan is subject to is less, reduce the adverse effect of centrifugal force to blower fan as far as possible, ensure the serviceable life of blower fan; The power lead, the electrical signal line that on the utility model electric vibration table, need pass-out, all pick out through brush, thereby can be connected and fixed on the electric cabinet of side, ensured the reliable of circuit connection.
