Abstract
The utility model relates to a spring oscillator demonstration instrument which is suitable to the middle school classroom to be used as a demonstration experiment. In order to completely record the vibration curve of simple harmonic oscillation of a spring oscillator, the spring oscillator demonstration instrument adopts a magnetic particle display board to record the track of the oscillation of a magnetic oscillator in time. The spring oscillator demonstration instrument has the specific technical proposal that: the magnetic display board moves along lead rails by uniform speed under the driving of a drive unit during the oscillation of the oscillator, wherein, the lead rails are vertical to the oscillation direction of the spring oscillator, and the plane of the display board sliding along the lead rails is vertical to the oscillation direction of the spring oscillator. The spring oscillator demonstration instrument draws materials simply, is convenient for manufacture, and is easy to be popularized.
Description
Affiliated technical field
The utility model relates to a kind of device of demonstrating spring oscillator simple harmonic oscillation process, is applicable in the classroom as lecture experiment.
Background technology
Present but very simple and crude of the experimental apparatus of the spring simple harmonic oscillation on the classroom in the teaching, be generally and adopt oscillator under the effect of spring, to do simple harmonic oscillation, everybody adopts the way with the eye Direct observation, though this kind method and instrument are effectively directly perceived, but but can not note spring really and make the whole process of simple harmonic oscillation and the attenuation process of simple harmonic oscillation, this is to further understanding and research very the inconvenience of classmates to the simple harmonic oscillation of spring.
Summary of the invention
The technical problem to be solved in the present invention has provided a kind ofly can know that the record spring oscillator makes the spring oscillator demonstrator that the track of simple harmonic oscillation is observed and learnt to make things convenient for classmates.
The technical scheme of utility model is: the spring oscillator demonstrator, comprise support, and be arranged on the magnet spring oscillator of an end of support upper spring; Described demonstrator also comprises the magnetic display board that can show the spring oscillator oscillation trajectory, also be provided with the guide rail vertical on the described support with the spring oscillator direction of vibration, described display board is parallel with the spring oscillator direction of vibration along the plane that guide rail slides, and also is provided with the drive unit that display board is slided along guide rail on the described support.Described drive unit is for to be provided with rotating leading screw and propulsion system on support, described display board is provided with corresponding screw, and the match driving that is incorporated in propulsion system of the screw on described leading screw and the display board drives down display board and slides along guide rail.
The utility model biggest advantage is exactly the track of energy real time record vibration, in addition, adopt simple screw type transmission magnetic display board, both can simplified structure, the stability and the homogeneity of the slip of magnetic display board have been promoted again, the adjustment bolt of frame bottom can be adjusted the level of support easily, so that experimental result is more accurate.
Description of drawings
Below in conjunction with accompanying drawing and concrete experimental procedure the utility model is further specified.
Fig. 1 is a front elevation of the present utility model;
Fig. 2 is a left view of the present utility model.
1. supports among the figure, 2. magnetic display board, 3. guide rail, 4. leading screw, 5. propulsion system are 6. adjusted bolt, 7. spring oscillator,
Embodiment
The utility model comprises that the bottom has the support (1) of four legs, and adjustment support level for convenience can be provided with in the bottom of support (1) adjusts bolt (6); An end of going up the spring that is provided with at support (1) is provided with magnet spring oscillator (7); Demonstrator also comprises the magnetic display board (2) that can show spring oscillator (7) oscillation trajectory, on support (1), also be provided with the guide rail (3) vertical with spring oscillator (7) direction of vibration, magnetic display board (2) is slidingly matched with guide rail (3) and is arranged on the support (1)---on the plane parallel and each other certain at interval distance with spring oscillator (7) direction of vibration, on support (1), also be provided with the drive unit that display board (2) is slided along guide rail (3), this drive unit is gone up rotating leading screw (4) and propulsion system (5) composition for being installed in support (1), and on display board (2), be provided with and the corresponding screw of leading screw (4), the match driving that is incorporated in propulsion system (5) of leading screw (4) and screw on the display board (2) drives display board (2) down and reciprocatingly slides along guide rail (3).Because this spring oscillator demonstrator is a physical experiment apparatus, do not need great power, so the wheel box that these propulsion system (5) can adopt little variable-frequency motor to drive, the wheel box that also can adopt little direct current generator to drive is realized the driving to leading screw (4).
The spring oscillator demonstrator has adopted simple structure to solve the problem that the student can not note the simple harmonic oscillation of spring fully when doing the spring simple harmonic oscillation, has made things convenient for the research of student to simple harmonic oscillation, has strengthened the further understanding to simple harmonic oscillation.And if change the spring in the utility model into rope, and with the below that is arranged on oscillator of magnetic display board level, and, then can realize complete documentation to the simple harmonic oscillation track of rope pendulum at the uniform velocity to slide on the direction vertical with the oscillator swaying direction.
Claims (1)
1, the spring oscillator demonstrator comprises support, is arranged on spring oscillator and display board on the support, it is characterized in that: described spring oscillator is a magnetic oscillator, and described display board is the magnetic display board.
