Compared with prior art, advantage of the present utility model comprises: should be simple in structure based on magnetostrictive vibration rig, stable work in work, frequency of operation can conveniently be adjusted in a big way, can improve the accuracy of test result, and it can not produce amount of heat in the course of the work, basic noiselessness pollutes, also without adopting cooling body, energy consumption is low, has wide application prospect.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation based on magnetostrictive vibration rig in the utility model one exemplary embodiments.
Embodiment
Below in conjunction with accompanying drawing and preferred embodiment, the technical solution of the utility model is further described.
The present embodiment relates to a kind of based on magnetostrictive vibration rig, and it comprises support, magnetostriction mechanism and work top, and described magnetostriction mechanism is arranged on support, and its movable end is fixedly connected with described work top through at least one leverage.
Should the principle of work based on magnetostrictive vibration rig be: by applying pumping signal to magnetostriction mechanism, make magnetostriction mechanism do stretching motion with certain frequency and amplitude, and then by leverage, this stretching motion is amplified, and make work top synchronous vibration, thereby produce required Oscillation Amplitude and frequency, meet the needs of vibration-testing.
Further, aforementioned leverage can adopt leverage, and it can comprise a lever, and described lever one end is connected with the movable end of described magnetostriction mechanism, the other end is fixedly connected with described work top, and the select location place between described lever two ends is also provided with a supporting device.
Aforesaid " connection ", is preferably and is rigidly connected.
For realizing the amplification of the vibration action being produced by magnetostriction mechanism, preferred, should make supporting device be arranged between described lever two ends and near magnetostriction mechanism one side, especially make the close described as much as possible magnetostriction of supporting device mechanism.
In the present embodiment, the material of magnetostriction mechanism can be selected from magnetostrictive Metal and Alloy, if nickel and golden coal (Ni) base alloy (Ni, Ni-Co alloy, Ni-Co-Cr alloy) and ferrous alloy are (as F e-Ni alloy, Fe-Al alloy, Fe-Co-V alloy etc.) and ferrite mangneto telescopic material, as Ni-Co and Ni-Co-Cu Ferrite Material etc., also can be selected from rare earth intermetallic compound magnetostriction materials, for example, with (Tb, Dy) Fe
2compound is the alloy of matrix etc.
