Abstract
The present invention relates to Popular Science Education technical fields, more particularly to a kind of device for demonstrating rigid-body vibration, including stage body and the table top being located on the stage body, the first straight line guide rail and second straight line guide rail of perpendicular arrangement are equipped on the table top, being mounted on the first straight line guide rail is sliding handle, what is be connected with the sliding handle is spring leaf, and being located on the second straight line guide rail is to stir handle, the other end stirred handle and be connected to the spring leaf.A kind of device for demonstrating rigid-body vibration of the present invention, the relationship of vibration frequency and rigid body length mainly for rigid body allow spectators to think deeply in interesting interactive operation, understand the vibration frequency of rigid body and the relationship of rigid body length: rigid body is longer, vibration frequency is lower, and rigid body is shorter, and vibration frequency is higher.
Description
Technical field
The present invention relates to Popular Science Education technical field more particularly to a kind of devices for demonstrating rigid-body vibration.
Background technique
The vibration (also known as vibrating) of object refers to the process of that a state changes.That is the reciprocal fortune of object or object a part
It is dynamic.Vibration frequency f is the number of object internal vibration each second circulation, and international unit is hertz [Hz].Frequency is vibration characteristics
Mark, be analyze vibration cause important evidence.The vibration frequency of rigid body and the length of rigid body have any relationship, currently without
Occur demonstrating the device of this relationship.
Summary of the invention
A kind of dress of the demonstration rigid-body vibration provided it is an object of the invention to overcome problems of the prior art
It sets.
In order to solve the above technical problems, the present invention adopts the following technical scheme that:
It is a kind of demonstrate rigid-body vibration device, including stage body and the table top being located on the stage body, on the table top be equipped be in
The first straight line guide rail and second straight line guide rail of vertical arrangement, being mounted on the first straight line guide rail is sliding handle, with
What the sliding handle was connected is spring leaf, and being located on the second straight line guide rail is to stir handle, described to stir handle company
It is connected to the other end of the spring leaf.
Compared with prior art, the invention has the benefit that
A kind of device for demonstrating rigid-body vibration of the present invention, the relationship of vibration frequency and rigid body length mainly for rigid body allow sight
Crowd thinks deeply in interesting interactive operation, and understand the vibration frequency of rigid body and the relationship of rigid body length: rigid body is longer, vibration frequency
Lower, rigid body is shorter, and vibration frequency is higher.
Detailed description of the invention
Fig. 1 is schematic view of the front view of the present invention；
Fig. 2 is schematic cross-sectional view at A-A of the present invention；
Fig. 3 is overlooking structure diagram of the present invention.
Specific embodiment
Referring to shown in attached drawing 1-3, a kind of device for demonstrating rigid-body vibration, including stage body 1 and the platform being located on the stage body 1
Face 2 is equipped with the first straight line guide rail 3 and second straight line guide rail 4 of perpendicular arrangement on the table top 2, is mounted on described first
In linear guide 3 is sliding handle 5, and what is be connected with the sliding handle 5 is spring leaf 6, is located at the second straight line guide rail 4
On be to stir handle 7, the other end stirred handle 7 and be connected to the spring leaf 6.
First straight line guide rail 3 is set to the right side position (direction as shown in Figure 3) of stage body 1 in apparatus of the present invention, slides hand
Handle 5 is mounted on the first straight line guide rail 3, and sliding handle 5 can be slided in first straight line guide rail 3, the both ends of spring leaf 6
It is connected to the sliding handle 5 and stirs on handle 7, the handle 7 of stirring is located on the second straight line guide rail 4, behaviour
It when making, holds and stirs handle 7, upward sliding stirs one end of spring leaf 6, so that spring leaf 6 freely swings, observes spring leaf 6
Vibration frequency；Sliding handle 5 is held, is slided to the right, the other end of spring leaf 6, the length that spring leaf 6 is swung are pulled
Degree shortens, and in the process, observes the variation of 6 hunting frequency of spring leaf.
Observer can have found: as sliding handle 5 moves to the right, the length that spring leaf 6 can vibrate is smaller, vibration frequency
Rate then can be faster.To verify the principle of demonstration rigid-body vibration.
The above description is only the preferred embodiments of the present invention, is not intended to limit the present invention in any other form,
Any person skilled in the art is changed or is modified as equivalent variations possibly also with the technology contents of the disclosure above
Equivalent embodiment.But without departing from the concept of the present invention, above embodiments are done according to the technical essence of the invention
Any simple modification, equivalent variations and remodeling, still fall within protection scope of the present invention.
