Embodiment 1

[0028] Example 1:

[0029] figure 1 It is the embodiment diagram of the bifurcation phenomenon demonstrator. It consists of demonstration part, power and mechanical transmission part and fixed support part. The power and mechanical transmission part includes motor 1, motor speed control box 2, T-shaped rotating bracket 4 and bearing 12 (deep groove ball bearing N6206 is used). The demonstration part includes demonstration slip ring 7, U-shaped rotating ring 6 (made of φ12 aluminum material, threaded at both ends, fixed to both ends of eccentricity adjustment plate 5 with 2 M8 nuts), eccentricity adjustment plate 5 (330 ×50×10 made of aluminum material, with φ10 holes at both ends), and 8 lamps. The fixed support part of the demonstrator includes an upper beam plate 9 (700×150×16), a lower beam plate 10 (700×150×20), a support frame 11 and a motor fixing frame 3 . The connection method is: the upper beam plate 9 and the lower beam plate 10 are respectively horizontally fixe...

Abstract

The invention provides a branched phenomenon display in the field of teaching display apparatus. It is formed by a display part, a power and mechanism transmission part and a fixed supporting part; it comprises a motor 1, a bear 12, a rotating frame 4, an eccentricity adjustment panel 5, a U type rotating ring 6, a display slide ring 7, an upper layer beam plate 9, a lower layer beam plate 10, a supporting frame 11 and a motor speed adjusting control box 2 and so on. The motor axle is connected with the rotating frame 4. The rotating frame 4 is covered on the eccentricity adjustment panel 5; the U type rotating ring 6 with display slide ring 7 is fixed on the eccentricity adjustment panel 5.

Description

[0001] Field: [0002] The invention belongs to a demonstration instrument for teaching and scientific research, and relates to a mechanical bifurcation, in particular to a demonstration instrument for a pitch fork (fork type) bifurcation phenomenon. Background technique: [0003] Bifurcation phenomenon is a ubiquitous phenomenon in modern mechanics, and it has the characteristic of uncertainty. In actual work, the concept of bifurcation phenomenon is relatively abstract and difficult to understand, which often leads to problems such as vague concepts. It is not conducive to the development of teaching and scientific research. At present, there is no suitable and intuitive teaching instrument for demonstrating the bifurcation phenomenon, which affects the quality of teaching. In order to meet the needs of teaching and scientific research, it is necessary to develop a bifurcation phenomenon demonstration instrument. Invention content: [0004] Solve the problem: [0005] ...
