Embodiment 1

[0022] Such as Figure 1-2 As shown, an experimental device using a DC vibrating motor as a vibration wave source includes a test bench 9, a DC power supply velocimeter 1 is arranged on the left side of the upper end of the test bench 9, and the lower right of the DC power supply velocimeter 1 is located at the upper end of the test bench 9 The left middle part is fixed with a column, and the upper end of the column is fixed with a fixed plate 3, and the upper middle of the fixed plate 3 is fixed with a vibration motor part 4. The vibration motor part 4 is mainly composed of a vibration motor, a fixed frame, a speed measuring disc and a photoelectric gate. At the left position of component 4, there is a terminal 2 connected by wires, and the terminal 2 is fixed on the fixed plate 3 and connected with the DC power supply speedometer 1 by wires, and the upper right side of the test bench 9 is fixed with a guide wheel mechanism 6. The upper right end of the guide wheel mechanism ...

Embodiment 2

[0025] Such as image 3 As shown, an experimental device using a DC vibration motor as a vibration wave source, the fixed knob 51 includes a knob head 511, a screw rod 512 and a rubber pad 513, the lower end of the knob head 511 is fixed with a rubber pad 513, and the upper side of the rubber pad 513 is located at the upper limit. The upper end of the plate 54 is sleeved with a screw rod 512 .

[0026] When in use, the extension part of the vibrating string 7 wound on the winding post 53 is wound on the screw rod 512, and is located between the two rubber pads 513. Grab the knob head 511 and force it to drive the screw rod 512 and the upper limit plate 54 to spiral. Rotate to fix the vibrating string 7, and the concave-convex pattern on the surface of the knob head 511 increases the friction force. During the rotation process, the vibrating string 7 is protected by two rubber pads 513 to reduce the friction force and prevent the vibrating string 7 from being severely worn. Pr...

Abstract

The invention provides an experimental device taking a direct-current vibration motor as a vibration wave source and an experimental method thereof, and relates to the field of physical experiments. The experimental device comprises an experiment table, and a convenient fixing device is fixed at the left end of a vibration string. According to the invention, the vibrating string is wound on a winding column, the vibrating string is embedded into a wire slot on the winding column to be compactly wound and not easy to scatter, and the vibrating string is prevented from being separated from the winding column during winding through the upper and lower limiting of the fixed bottom plate and an upper limiting plate in the winding process, and is wound on a fixed knob for fixing after being wound; through double fixing, the vibration string is stably installed and cannot be scattered, the vibration conduction performance is improved, and the problem that the whole experiment is affected dueto the fact that the vibration string is easily loosened in the spiral rotation process of fixing bolts is solved.

Description

technical field [0001] The invention relates to the field of physical experiments, in particular to an experimental device and an experimental method using a DC vibration motor as a vibration wave source. Background technique [0002] At present, in the field of mechanical thermophysical string vibration experiments, the vibration frequency of the vibration motor as the wave source is measured by using the experimental device of the DC vibration motor as the vibration wave source. [0003] During the experimental installation, the vibrating string is generally wound around the bolt and then fixed on the fixed plate, but this fixing method will easily loosen the vibrating string during the rotation process, so that the connection of the vibrating string is not firm, which affects the overall experiment . Contents of the invention [0004] The object of the present invention is to provide an experimental device and an experimental method using a DC vibration motor as a vibr...
