The utility model provides a demonstration device based on forced vibration and resonance phenomenon, which relates to the technical field of forced vibration and resonance phenomenon demonstration instruments, and comprises a base, the main body of the base is of a box body structure, the bottom end of the base is provided with a groove, and the top end surface of the base is provided with a transverse groove. A transverse groove formed in the top end of the base is used for allowing a steel wire to penetrate through, the inner side of the base is fixedly connected with guide frames, the number of the guide frames is two, and the problem that in the prior art, rapid display operation cannot be conducted according to different stirring amplitudes during demonstration, and then the test effect is affected is solved. A steel wire pulled by a traction rope is automatically reset and rebounded through a moving block under the rebounding and resetting action of a spring plate, so that students can conveniently lea
