Specific embodiment
A kind of two-dimentional experiment with simple pendulum device, including base 1, the base 1 are A fonts（As shown in Figure 1）, the base 1
On be provided with circle vertical rod 2, cross adapter 3 is provided with the vertical rod 2, cross bar 4 is provided with the vertical rod 2, it is described
The vertical rod 2 and cross bar 4 are connected by cross adapter 3 so that 4 one-tenth 90 degree of settings in length and breadth of the vertical rod 2 and cross bar.The horizontal stroke
Fixing device 5 is provided with bar 4, receiver 7 is provided with the cross bar 4, the receiver 7 is connected with display device（In figure
Indicate）, the cross bar 4 and reception device 7 are connected by fixing device 5.The fixing device lower section is provided with hanging rope 6,
Transmitting ball 8 is provided with the hanging rope 6, emitter is installed on the transmitting ball 8, can will launch the physical quantity of ball 8（As transported
Dynamic trajectory diagram）Be converted to signal to launch, data are received and converted into by the receiver 7 and the week of simple harmonic motion is analyzed
Phase amplitude etc., above-mentioned data are sent to display device by last receiver 7 intuitively to be manifested.
Application method of the present utility model is as follows：
The first step, installs vertical rod 2：Base 1 is lain on horizontal laboratory table, vertical rod 2 is arranged on base 1, vertical rod 2
Fixed with base 1 by way of rotation, and vertical rod 2 and the middle shell tool of base 1；
Second step, fixing device for installing 5：Fixing device 5 is enclosed within vertical rod 2 by lucite support frame, tightens knob
It is fixed；
3rd step, installs receiver 7：Receiver 7 is inserted in fixing device 5, then is screwed down；
4th step, installs transmitting ball 8, hanging rope 6 is tied up to the two ends of transmitting ball respectively, then the other end of hanging rope 6 is distinguished
It is clipped in fixing device 5 so that transmitting ball 8 keeps left and right horizontal；
5th step, with horizontal alignment instrument to installing after the utility model calibrate；
6th step, swings transmitting ball 8, launches the transmission signal of ball 8, and receiver 7 receives signal and shows on the display apparatus
Physical quantity（Movement locus, the cycle amplitude of simple harmonic motion）, printing completion.
The utility model sets the receiver 7 and transmitting ball 8 for cooperating, and letter is launched by the simple harmonic motion for launching ball 8
Number, receiver 7 receives signal and changes, i.e. the utility model can immediately arrive at the movement locus figure of simple harmonic motion, and analyze
The physical quantitys such as the cycle amplitude of simple harmonic motion, experimental result is objective bright and clear, and clear with track, accuracy is high, and data are objective, mistake
The characteristics of journey is easy-to-understand, is particularly well-suited to demonstration lesson.
Above example is only used to illustrate the technical solution of the utility model and unrestricted, those of ordinary skill in the art couple
Other modifications or equivalent that the technical solution of the utility model is made, without departing from technical solutions of the utility model
Spirit and scope, all should cover in right of the present utility model.
