Description

technical field [0001] The invention relates to a simple coupling pendulum experiment device, which belongs to the technical field of teaching experiment instruments. Background technique [0002] Interacting vibrational systems are common in nature, such as the oscillating loop coupled by capacitance and inductance in electricity, the vibration modes of adjacent atoms in a solid lattice, and the electromagnetic coupling field generated by the coupling of photons and phonons. The interaction will make the vibrating system exhibit rich kinematic behavior, and it is very necessary to study this. However, the mechanically coupled pendulum is used as the research object in the current experimental device, and the behavior of the coupled pendulum under different initial conditions cannot be well observed. The vibration characteristics and the degree of coupling are the influencing factors on the vibration characteristics of the coupled pendulum, and the effect of the existing dev...

The interaction will make the vibrating system exhibit rich kinematic behavior, and it is very necessary to study this. However, the mechanically coupled pendulum is used as the research object in the current experimental device, and the behavior of the coupled pendulum under different initial conditions cannot be well observed. The vibration characteristics and the coupling degree are the factors that affect the vibration characteristics of the coupled pendulum, and the effect of the existing device demonstration is not obvious during the experiment, and some operational failures will occur, which is not conducive to the learning of students and the teaching of teachers.
