Description

Technical Field

[0001] The utility model relates to the technical field of electrical teaching aids, in particular to a chaotic pendulum. Background Art

[0002] Chaos refers to a complex, seemingly irregular pattern of motion in the real world. Its common characteristic is that, under certain conditions, orderly motion, once following simple physical laws, suddenly deviates from the expected regularity and becomes disordered. Chaos can occur in a wide range of deterministic dynamical systems. Its statistical properties resemble those of random processes and are considered an inherent form of randomness within deterministic systems.

[0003] During the teaching process, teachers usually draw chaotic structures on the blackboard and try their best to describe the state of chaotic phenomena. However, due to the invisibility of chaos itself, intuitive teaching is difficult. Utility Model Content

[0004] In view of the above-mentioned deficiencies, the main purpose of the present invention is to provide a chaotic pendulum, which can observe the uncertainty of the swing through an intuitive chaotic pendulum mechanism.

[0005] The above purpose of this utility model is achieved through the following technical solutions:

[0006] A chaotic pendulum comprises a first pendulum, a second pendulum and a third pendulum of symmetrical structure, wherein one end of the second pendulum and the third pendulum are respectively fixed to a flange bearing, and the flange bearing is connected to an upper rotating shaft.

[0007] The other ends of the second pendulum and the third pendulum are connected to the first pendulum via a lower rotating shaft.

[0008] The first pendulum is arranged between the second pendulum and the third pendulum. Both sides of the first pendulum and one side of the second and third pendulums are fixed to the lower rotating shaft through flange bearings.

[0009] Preferably, the length of the second pendulum is greater than that of the first pendulum.

[0010] Preferably, a counterweight flange bearing is provided at the bottom of the first pendulum, and the counterweight flange bearings are arranged on two symmetrical sides of the first pendulum. The counterweight flange bearings can also be easily replaced.

[0011] Preferably, support frames are provided on both sides of the upper rotating shaft, and the support frames are fixed on the base.

[0012] Preferably, both ends of the first pendulum and the second pendulum are symmetrical structures.

[0013] Beneficial effects of the utility model:

[0014] The utility model raises the first pendulum, the second pendulum and the third pendulum, and thus the irregularity of the movement can be discovered by observing the swing or flipping of the first pendulum, the second pendulum and the third pendulum. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] See also Figure 1 A chaotic pendulum is disclosed, comprising a first pendulum, a second pendulum and a third pendulum of symmetrical structure, wherein one end of the second pendulum and the third pendulum are respectively fixed to a flange bearing, and the flange bearing is connected to an upper rotating shaft.

[0020] The other ends of the second pendulum and the third pendulum are connected to the first pendulum via a lower rotating shaft. The first pendulum is arranged between the second pendulum and the third pendulum. Both sides of the first pendulum and one side of the second and third pendulums are also fixed to the lower rotating shaft via flange bearings.

[0021] See also Figure 2 , is a schematic diagram of the preferred structure of the first pendulum. The upper and lower ends of the first pendulum and the second pendulum are symmetrical structures, which are easy to install and have stable structure. Both ends of the first and second pendulums are provided with a center hole, and fixing holes are provided around the center hole. There are 4 fixing holes.

[0022] A counterweight flange bearing is provided at the bottom of the first pendulum. The counterweight flange bearings are provided on both symmetrical sides of the first pendulum, which not only maintains the balance of the first pendulum but also facilitates the adjustment of counterweights of different weights to experiment with the swinging state under different weights.

[0023] In the preferred structure, the first pendulum and the second pendulum have substantially the same shape and are both centrally symmetrical structures, and the vertical length of the second pendulum is greater than the vertical length of the first pendulum.

[0024] It should be noted that the flange bearings in this device are structures in which a bearing is fixed in the middle of the flange, and all of them are of the same size and shape.

[0025] In a preferred structural solution, the flange bearings are arranged on the opposite inner sides of the second and third flange bearings, making the structure symmetrical and compact.

[0026] Working method: Raise the first pendulum, the second pendulum, and the third pendulum repeatedly to make the entire pendulum system swing. Observe the swing pattern. Through repeated observation, you will find that the swing state is different each time. Even if the control height is basically the same, the swing pattern will not be exactly the same. This experimental teaching aid can inspire students to practice irregular movements in teaching experiments, and it is vivid and intuitive.

[0027] The one or more embodiments of this specification are intended to cover all such substitutions, modifications, and variations that fall within the broad scope of the appended claims. Therefore, any omissions, modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of one or more embodiments of this specification shall be included within the scope of protection of this disclosure.
