Embodiment 1

[0032] like Figure 1-3 As shown, a kind of portable vibration teaching experimental platform provided by the present invention comprises: box body 1, elastic body 14, a plurality of first vibrating bodies 15, vibrator 18, first visual sensor 11, a plurality of second vibrating bodies 13. The second visual sensor 12, display 7 and controller

[0033] Box 1;

[0034] The elastic body 14 is connected to the inner wall of the box body 1 at one end;

[0035] A plurality of first vibrating bodies 15, the plurality of first vibrating bodies 15 have different quality specifications, in the plurality of first vibrating bodies 15, any one of the first vibrating bodies 15 is detachably connected to the other end of the elastic body 14, the first The vibration body 15 is slidingly connected with the inner bottom wall of the box body 1;

[0036] The exciter 18 is arranged inside the box body 1, and the exciter 18 is connected with the first vibrating body 15;

[0037] The first visual...

Embodiment 2

[0046] On the basis of Embodiment 1, in order to prevent the first vibrating body 15 and the second vibrating body 13 from deflecting during vibration, thus affecting the reliability of the experimental results.

[0047] like figure 2 and 3 As shown, wherein, the inner bottom wall of the box body 1 is provided with a chute 2, the bottom of each first vibrating body 15 and the bottom of each second vibrating body 13 are provided with a slider 5, and the slider 5 is connected to the bottom of the second vibrating body 13. The chute 2 is slidingly connected.

[0048] By arranging the chute 2 and the slider 5, through the guiding effect of the chute 2, it can be ensured that the vibration direction of the first vibrating body 15 and the second vibrating body 13 is single and does not deflect when vibrating, thereby effectively ensuring the experimental results reliability.

Embodiment 3

[0050] On the basis of Embodiment 2, in order to reduce the friction force between the first vibrating body 15 and the box body 1, the friction force between the second vibrating body 13 and the box body 1, and the friction force between the slider 5 and the chute 2 influence on the experimental results.

[0051] like image 3 As shown, wherein there is a gap between the side wall of the chute 2 and the slider 5, the bottom of the chute 2 is provided with a plurality of exhaust ports 6 arranged along the length direction of the chute 2, and the box body 1 A vent hole 9 is provided at the bottom, and each exhaust port 6 communicates with a gas source device through the vent hole 9, and the gas source device is electrically connected to the controller.

[0052] There is a gap between the side wall of the chute 2 and the slider 5. By setting the exhaust port 6, the air is exhausted between the contact surface of the slider 5 and the chute 2. Under the effect of the air floating ...

Abstract

The invention discloses a portable vibration teaching experiment table, and belongs to the technical field of vibration experiment equipment. The portable vibration teaching experiment table comprises a box body; an elastic body; a plurality of first vibrating bodies which are detachably connected to the other end of the elastic body; a vibration exciter; a first visual sensor used for collecting vibration parameters of the first vibration body; a plurality of second vibrating bodies which are detachably connected to the elastic body; a second visual sensor used for collecting vibration parameters of the second vibration body; a display; and a controller electrically connected with the vibration exciter, the first visual sensor, the second visual sensor and the display, wherein the controller is also electrically connected with a memory. The portable vibration teaching experiment table provided by the invention can verify the coupling relationship of vibration between two groups of vibrators under forced vibration and the influence of the quality of the vibrators on the vibration coupling result under the vibration excitation of the same vibration parameter.

Description

technical field [0001] The invention relates to the technical field of vibration experiment equipment, in particular to a portable vibration teaching experiment platform. Background technique [0002] Vibration is a common phenomenon in the operation of equipment. In teaching, in order to let students understand the vibration phenomenon more intuitively, it is necessary to conduct vibration experiments, and to conduct vibration experiments, it is necessary to use a vibration teaching test bench. [0003] The existing vibration teaching experiment platform lacks the design to verify the coupling relationship of vibration between two groups of vibrating bodies under forced vibration, and it is difficult to verify the mutual vibration between two vibrating bodies connected by elastic bodies under forced vibration. The law of influence. Contents of the invention [0004] The purpose of the present invention is to overcome the problems in the prior art, to provide a portable v...
