Description

A kind of vibration demonstration instrument

Affiliated technical field

The utility model relates to a kind of demonstration instrument for teaching, particularly a kind of vibration demonstration instrument.

Background technology

At present, in physics teaching, experiment is a kind of very effective means of exploitation students ' practical ability and elaborative faculty, and it can improve students'interest in learning greatly.And teaching demonstration has very big benefit to cultivating students'interest in learning, in the classroom instruction of damped vibration, forced vibration and resonance, the demonstrator demonstration is arranged, and the teacher can be better and student's interaction.

Summary of the invention

The purpose of this utility model provides a kind of vibration demonstration instrument, can demonstrate the physical phenomenon of damped vibration, forced vibration and resonance easily and intuitively.

The purpose of this utility model is achieved in that vibration demonstration instrument is made up of bearing, spring, support, aluminum pipe, magnon, arc aluminium sheet, aluminium ring, carriage, base, fixed knob and fixed cover, it is characterized in that: support is fixed on the base, support one end is equipped with bearing, one end of spring links to each other with bearing, one end of the other end and aluminum pipe links to each other, the other end of aluminum pipe is equipped with magnon, on support, put fixed cover, fixed cover links to each other with carriage, fixed knob is arranged on the fixed cover, on carriage, be placed with arc aluminium sheet and aluminium ring.Magnon is made with novel rare-earth material neodymium iron boron, is shaped as cylindrical.

Because adopt technique scheme, advantage and good effect that the utility model had are: the physical phenomenon of demonstration damped vibration, forced vibration and resonance, come into plain view, easy and simple to handle.
