Abstract
The utility model relates to a vibrating device who is fit for wide band section, a serial communication port, including six curb plates and bottom plate, six curb plates enclose into regular hexagon, there are a plurality of mounting holes on the curb plate, there is equipment guide pillar hole on the bottom plate. The beneficial effects of the utility model are that, this vibrating device is fit for being used for the vibrating device of wide band section, and frequency sweep natural frequency is higher than 1000Hz to can compromise the multiple product can use on a pair vibrating device. In frequency range 10-1000Hz, the additional resonance of disappearance, the amplitude of guaranteeing to vibrate rack output pass through vibrating device and transmit specimen sample and go up undistortedly, do not amplify, and the validity of testing is guaranteed to no peak resonance.
Description
Technical field
The utility model relates to frequency experiment test device, is specifically related to a kind of vibrating device of wide-band.
Background technology
At present, it is narrow that traditional vibrating device is applicable to frequency range, and the operating condition of test that amplitude is little.Go if used by traditional device in the vibration test of wide-band, the consequence brought is exactly that extraneous vibration is large, also has the problems such as natural frequency due to vibrating device itself, vibration test is lost defer to test frequency spectrum and carrys out certification test part object.Vibration is divided into three directions (vertical, front and back, level), ordinary test device, and vertical and anterior-posterior horizontal direction has been come by roll-over test excitation stand, and the change of front and back, horizontal direction then realizes by the upset of vibrating device.Because vibrating device and part to be tested will simulate actual mounting means, so vibrating device cannot share.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of and considers the existing vibration stand of coupling, and be suitable for the vibrating device of wide-band, and frequency sweep natural frequency higher than 1000Hz, and can be taken into account multiple product and can use on a secondary undulation device.
To achieve the above object of the invention, provide a kind of vibrating device of applicable wide-band, comprise six side plates and base plate, six side plates surround regular hexagon; Described side plate there is multiple mounting hole, described base plate has equipment guide pillar hole.
Be connected with needs tested parts by side plate mounting hole, be connected with vibration stand by equipment guide pillar hole.Vibratory equipment is driving source, is delivered to by testpieces by vibrating device, and keeps original machine to export, and does not amplify, does not occur resonance, reach verification experimental verification object.Six side plates surround whole regular hexagon, according to the direction of vibration, select suitable mounting plane.
Preferably, the inner side that reinforcing prop is secured by bolts in each side plate is also comprised.Reinforcing prop plays this effect of reinforcing side plate.
Preferably, described mounting hole is and threaded hole.
Preferably, each side have the different mounting holes of plurality of specifications.The mounting hole of different size is applicable to the experiment part installation of different cultivars.
Preferably, described side plate and base plate are bolted, and described side sheet room is bolted.
The vibrating device of applicable wide-band of the present utility model, in vibration test, as the transmission medium of centre and vibration stand, assembling medium between tested parts.Vibrating device and vibration stand, tested parts and side plate mode all with bolts.Be assemblied on suitable side plate according to different direction of vibration.Vibration stand exports vibration amplitude, in frequency range 10 ~ 1000Hz, does not occur due to the additional resonance of vibration rack, guarantee that the amplitude vibrating stand output is delivered on test specimen undistorted by vibrating device, do not amplify, without spike resonance, guarantee the validity tested.Compared with prior art, the utility model has the following advantages: (1) frequency range is wide, and resonance is little: be applicable to test vibration frequency 10 ~ 1000Hz, and amplitude reaches 2G, before vibration, frequency sweep natural frequency is greater than 1000Hz; (2) highly versatile: owing to adopting six side plates, part can according to direction of vibration, and alternative is arranged on correct position, and can do multiple stage tested parts simultaneously.Different part can select different mounting holes to carry out installation test on side plate; (3) easy to assembly: the side plate of vibrating device own, reinforcing prop, base plate, side plate and tested parts, it is all adopt bolt arrangement to connect that base plate is connected with vibration stand, due to easy to assembly, makes the test preparatory period short; (4), there is not the resonance added in test validity: in frequency range 10 ~ 1000Hz, guarantees that the amplitude vibrating stand output is delivered on test specimen undistorted by vibrating device, do not amplify, without spike resonance, guarantee the validity tested.
The beneficial effects of the utility model are, this vibrating device is suitable for the vibrating device of wide-band, and frequency sweep natural frequency higher than 1000Hz, and can be taken into account multiple product and can use on a secondary undulation device.In frequency range 10 ~ 1000Hz, there is not the resonance added, guarantee that the amplitude vibrating stand output is delivered on test specimen undistorted by vibrating device, do not amplify, without spike resonance, guarantee the validity tested.

Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described further.
According to the vibrating device of a kind of applicable wide-band shown in Fig. 1 to Fig. 4, comprise six side plates, 1, six side plates 1 and surround regular hexagon, base is bolted by base plate 3, be bolted reinforcing prop 2 inside each side plate 1, reinforcing prop 2 plays the effect of reinforcing side plate 1.Side plate 1 has the mounting hole 4 of multiple different size, described mounting hole 4 is threaded hole, for being connected with needing the part of testing.Base plate 3 bottom surface there is equipment guide pillar hole 5, be connected with vibrations stand by equipment guide pillar hole 5.Vibratory equipment is driving source, is delivered to by experimental piece by vibrating device, reaches the object of experimental verification.
Above-mentioned side plate adopts metal material, has six pieces, has the mounting hole of different size above, and the tested parts being applicable to different cultivars is installed, and according to the direction of vibration, selects suitable mounting plane.
Be applicable to the vibrating device of wide-band, in vibration test, as the assembling medium between the transmission medium of centre and vibration stand, tested parts.Vibrating device and vibration stand, tested parts and side plate mode all with bolts.Be assemblied on suitable side plate according to different direction of vibration.Vibration stand exports vibration amplitude, in frequency range 10 ~ 1000Hz, does not occur due to the additional resonance of vibration rack, guarantee that the amplitude vibrating stand output is delivered on test specimen undistorted by vibrating device, do not amplify, without spike resonance, guarantee the validity tested.
