Abstract
The utility model discloses an apparatus for demonstrating locus of a magnetic chaotic pendulum. The apparatus comprises a pendulum hammer rack; and a pendulum hammer is suspended on the pendulum hammer rack. The apparatus is characterized in that the pendulum hammer is provided with a luminescence device; the pendulum hammer rack below the pendulum hammer is provided with a light filter panel; a camera device is arranged below the light filter panel; and the camera device is connected to a computer. The apparatus provided by the utility model has simple construction and low cost, can carry out shooting through commonly used laser pen and camera without changing an original structure of the magnetic chaotic pendulum, and can demonstrate the locus on a computer; besides, the apparatus has good effect and high sensitivity.
Description
Technical field
The utility model relates to magnetic Chaos Pendulum track demonstration field, specifically, relates to a kind of device of demonstrating magnetic Chaos Pendulum track.
Background technology
The magnetic Chaos Pendulum is the experimental provision of demonstrating chaos phenomenon.At present, common magnetic Chaos Pendulum is suspended pendulum on three fixing magnet normally, the pulling pendulum at an arbitrary position after, static release can be seen pendulum at the effect lower swing of three magnet, the route track of its motion can not be predicted fully.Although device is simple, can image demonstrate chaotic motion fully, so very common in the school physics laboratory.But this magnetic Chaos Pendulum apparatus for demonstrating can not record the track of pendulum motion, so also be difficult to obtain the conclusion that this is chaos phenomenon by direct viewing.Prior art is to increase computer interface, electromagnetism or photoelectric conversion device at the magnetic Chaos Pendulum to show movement locus.This mode cost of manufacture is relatively high, and comparison is complicated.This is the deficiencies in the prior art part.
The utility model content
The technical problems to be solved in the utility model provides a kind of device of demonstrating magnetic Chaos Pendulum track, the real time kinematics situation that shows the magnetic Chaos Pendulum directly perceived, go out simultaneously the movement locus of pendulum according to the motion real-time depiction of pendulum, the movement characteristic of image display magnetic Chaos Pendulum.
The utility model adopts following technical scheme to realize goal of the invention:
A kind of device of demonstrating magnetic Chaos Pendulum track, comprise the pendulum support, suspended pendulum on the described pendulum support, it is characterized in that: be provided with illuminator on the described pendulum, be provided with the light filter on the pendulum support of described pendulum downside, the downside of described light filter is provided with camera head, and described camera head connects computing machine.
As the further restriction to the technical program, described illuminator is laser pen.
As the further restriction to the technical program, described light filter is focussing glass.
As the further restriction to the technical program, described camera head is camera.
Compared with prior art, advantage of the present utility model and good effect are: laser pen of the present utility model is followed pendulum and is swung, the image of camera collection pendulum motion, the laser spots track of in computing machine camera being taken is analyzed, gray scale difference according to laser spots and focussing glass background colour, laser spots can be separated separately, movement locus described in record.The utility model simple structure, cost is low, need not change the structure of original magnetic Chaos Pendulum, can take by modal laser pen, camera, then demonstrates in computing machine, demonstrates respond well, highly sensitive.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing and preferred embodiment the utility model is done further to describe in detail.
Referring to Fig. 1, the utility model comprises pendulum support 1, pendulum 2, laser pen 3, focussing glass 4, camera 5, computing machine 6, suspended pendulum on the described pendulum support, be provided with illuminator on the described pendulum, be provided with the light filter on the pendulum support of described pendulum downside, the downside of described light filter is provided with camera head, and described camera head connects computing machine.
Described illuminator is laser pen.
Described light filter is focussing glass.
Described camera head is camera.
Laser pen of the present utility model is followed pendulum and is swung, the image of camera collection pendulum motion, the laser spots track of in computing machine camera being taken is analyzed, according to the gray scale difference of laser spots and focussing glass background colour, laser spots can be separated separately, movement locus described in record.The utility model simple structure, cost is low, need not change the structure of original magnetic Chaos Pendulum, can take by modal laser pen, camera, then demonstrates in computing machine, demonstrates respond well, highly sensitive.
Certainly; above-mentioned explanation is not limitation of the utility model; the utility model also is not limited only to above-mentioned giving an example, and the variation that those skilled in the art make in essential scope of the present utility model, remodeling, interpolation or replacement also belong to protection domain of the present utility model.
