Background technology
Along with the development of science and technology and the mankind are to the continuous exploration of new energy technology, piezo-electric generating technology is more and more subject to people and pays close attention to.The key of piezoelectric energy collector vibration experiment fixture experimental study piezoelectric vibration energy acquisition technique, the quality of laboratory holder directly affects the precision of experiment and then the result of influence research.The research of present stage bistable state straight beam generating effect and the research of bistable state L-type beam generating effect are very important.Can effectively realize jumping between trap, fine adjustment yoke distance be very important to experiment.Therefore the design for bistable state piezoelectric energy collector vibration experiment fixture is most important.
Summary of the invention
In order to more accurately regulate bistable state, regulate yoke distance more easily, the magnet that this bistable state piezoelectric energy collector vibration experiment fixture can realize being pasted onto pasting boards all around moves up and down and the rotation of 180 °.
For achieving the above object, the technical solution used in the present invention is a kind of bistable state piezoelectric energy collector vibration experiment fixture, and this fixture comprises pedestal 1, L-type bracing frame 2, L-type briquetting 3, briquetting 4, T word pasting boards 5, type pasting boards 6, slide block 7, scale 8, leading screw support 9, leading screw 10; Described slide block 7 is L shape structure, it is equipped with U-lag along the horizontal plane with on vertical plane, U-lag on described slide block 7 surface level coordinates with the turn leading screw 10 of pedestal 1 by pedestal 1 end, realize after rotational lead screw 10 moving left and right, leading screw 10 is supported by leading screw support 9, and leading screw support 9 is arranged on pedestal 1 end; With the pedestal 1 of slide block 7 cooperation place is carved with scale 8 can improves mobile accuracy; U-type groove on the U-type groove of type pasting boards 6 and slide block 7 vertical plane is bolted, and can realize upper and lower, the forward and backward movement of type pasting boards 6; T word pasting boards 5 is connected with type pasting boards 6 by bolt, realizes the rotation of 180 ° of angles on vertical plane.
T word pasting boards 5 and type pasting boards 6 are all pasted with magnet.
L-type bracing frame 2 is bolted on pedestal 1, L-type briquetting 3 is bolted on L-type bracing frame 2, L-type briquetting 3 and L-type bracing frame 2 combine the crossbeam that can realize L-type bracing frame 2 and clamp, and upper end and the briquetting 4 of L-type briquetting 3 combine the clamping realizing vertical beam or be inverted L-type beam.As Fig. 3 do bistable state straight beam vibration experiment time, by the magnet be pasted onto on type pasting boards 6 by above-mentioned upper and lower, left and right move realize align with beam end magnet, more convenient more easily reach test pre-conditioned; As Fig. 4 do the experiment of bistable state L-type beam vibration time, by the magnet of the T word pasting boards 5 be pasted onto topmost by rotating T word pasting boards 5 and move type pasting boards 6 and slide block 7 realizing and is inverted aliging of L-type beam end magnet, reach experiment pre-conditioned.
Advantage of the present invention is: 1, regulate yoke distance by rotational lead screw, moving up and down of magnet is realized by the cooperation of U-type groove, the change of magnet angle is realized by rotating T word pasting boards, further reduce in experiment in the past and change the position of magnet and the difficulty of angle, improve the precision of experiment further.2, this fixture can complete bistable state straight beam and the experiment of bistable state L-type beam vibration by L-type depression bar.

Embodiment
Below in conjunction with embodiment, the present invention is described in further detail.
Be bolted on actuating vibration table by pedestal 1, L-type bracing frame 2 is bolted on pedestal 1.As end being clamped in L-type bracing frame 2 lower end with the piezoelectric patches of magnet when Fig. 3 does bistable state straight beam vibration experiment, piezoelectric patches lead-in wire is worn out connection multimeter by U-type groove.Because bistable state straight beam vibration experiment does not need T word pasting boards 5 temporarily to take down.By another magnet pasting on convex pasting boards 6, by regulating type pasting boards 6, magnet is alignd with magnet on beam, by the movable of turn leading screw 10 adjusting slider 7 and then adjustment yoke distance, best bistable state state is found again, then with fixing slide block 7 and the type pasting boards 6 of tighting a bolt by fine setting.Change the yoke distance rotational lead screw about 10 that only need looser a bolt if want and finely tune type pasting boards 6.As clamped the inverted L-type beam of end with certain orientation magnet with briquetting 4 when Fig. 4 does the experiment of bistable state L-type beam vibration, piezoelectric patches lead-in wire is worn out connection multimeter by U-type groove.By another magnet pasting on T word pasting boards 5, will be pasted onto the magnet of T word pasting boards 5 by above-mentioned rotation T word pasting boards 5, mobile type pasting boards 6 and slide block 7 realize and are inverted aliging of L-type beam end magnet, reach experiment pre-conditioned.Change yoke distance if want only need to looser a bolt rotational lead screw 10, finely tune type pasting boards 6 up and down and rotate T word pasting boards 5.
In sum, the contrast that can realize bistable state straight beam vibration experiment and bistable state L beam vibration and test of the present invention, regulates bistable state more accurate, regulates yoke distance more convenient.
