Description
Technical field
The present invention relates to teaching and experiment equipment, relate in particular to a kind of oscillation image drawing apparatus for spring oscillator.
Background technology
In physics teaching in secondary school, make model with spring oscillator, depict the oscillating curve of spring oscillator, study rule, the demonstration spring oscillator motion phenomenon of simple harmonic oscillation and verify its Period Formula etc. according to oscillating curve.
The method of initial mapping oscillating curve is: spring oscillator is vibrated, test the teacher simultaneously and make manually recording chart advance, draw oscillating curve by recording pointer on recording chart.
The method of more than describing oscillating curve has the following disadvantages: manually draw recording chart and advance, not only require great effort, and the pace of recording chart is unstable, causes the poor accuracy of depicted curve; Experimental implementation is loaded down with trivial details, and existing spring oscillator, connects tracheae, interface etc. at the source of the gas that also needs other outfit to adapt with it, and the vibration period of measuring oscillator also needs to use timer (as stopwatch etc.).
China Patent No. be ZL2004200797650, Granted publication day are October 19 in 2005 day, designed a kind of vibrational image delineator that can overcome the problems referred to above in being called the patent documentation of " experiment instrument for simple harmonic vibration of spring vibrator ".Plotter in this patent comprises base, paper-advance unit and spring oscillator device; Paper-advance unit comprises the paper feed bearing, the paper feed axle that are arranged on base, drive into the motor that reel uses and be arranged on that same paper feed bearing on the paper feed axle matches drive the paper rubber tire; Spring oscillator device comprises air track, spring, bob and air pump, spring one end is connected on the pillar of air track left end, the other end is connected on the slide block on air track, bob is fixed on slide block, and recording pointer is spun solid at the bob bottom, and air pump connects with air track.During use, recording chart is located in from the below of air track is passed again and drives between paper rubber tire and paper feed bearing, motor drives into the reel uniform rotation, the paper feed axle drives the paper feed rubber tire to rotate, the paper feed rubber tire drives recording chart by friction force and advances, drive recording pointer in the vibrative process of spring oscillator and be synchronized with the movement, recording pointer draws oscillating curve on recording chart.
Although this patent has solved existing deficiency in the above-mentioned procedure of describing oscillating curve by design air pump and the paper-advance unit that driven with motor.But this patent also has the following disadvantages: for the process of rendering image, recording pointer is with contact is arranged between recording chart, can produce resistance in the process that recording pointer moves on recording chart, this resistance can cause recording chart to move ahead steadily and affect the vibration of spring oscillator, cause drawn curve can not accurate response to go out the Vibration Condition of spring oscillator, the i.e. poor accuracy of image, when calculating oscillator and running to from some the time (meaning with T) that another point consumes, can only at first measure between 2 the distance (meaning with S) along page orientation, then (this linear velocity is the pace of recording chart to extrapolate the linear velocity of the most peripheral of paper feed rubber tire according to the diameter of the rotating speed of motor and paper feed rubber tire, with V, mean), according to formula T=S/v, calculate time T, but when measuring S, the difference of people's reading that the thickness of lines is different and different, cause stochastic error larger, in addition in use, the paper feed rubber tire can produce wearing and tearing and cause diameter to change, thereby make V have larger deviation, therefore by this oscillating curve can not verify exactly relevant physical theory as the spring vibration cycle with the quality of oscillator and the relation between elasticity coefficient.
