Durable Vertical Spring Oscillator for Enhanced Mechanical Performance
1, Overview
This instrument is designed and produced according to the requirements of the newly compiled high school equipment catalog by the Ministry of Education, mainly for the study of the laws of harmonic vibration in middle school physics.
2, Structure and principle
The instrument consists of a mounting plate, base, pillar, spring, oscillator, scale, etc. (as shown in the figure below)
3, Usage method
1. Place the instrument on a horizontal table, adjust the knob on the shelf to adjust the height of the oscillator, and align the oscillator with the "0" position on the scale. Pull the oscillator downwards and deviate it from the "0" position for a certain distance. After releasing it, the oscillator begins to vibrate in an up and down cycle Observe the displacement distance where the amplitude deviates from "0", change the amplitude and redo several times to study the vibration pattern.
2. On the basis of the above experiment, the two oscillators on the left and right sides of the scale were pulled down to different distances from the "0" position, and then released. It was observed that the time for the two oscillators to return to the "0" position and reach the maximum displacement was the same.
3. From the experiment, it can be analyzed that the force acting on the oscillator at a certain position is F=- kx (K is the spring resistance coefficient, X is the displacement of the oscillator). Therefore, the acceleration at this time is:
The vibration under the action of reciprocating force that is proportional to displacement but opposite in direction is called harmonic vibration.
4. From the experiment, it can be analyzed that the sum of elastic potential energy and kinetic energy of oscillator m at any point X remains constant, equal to the elastic potential energy at the maximum displacement. The energy of harmonic vibration
(V is the velocity of oscillator m at displacement X, A represents the amplitude)
