Vibration experimental apparatus for education

摘要

PURPOSE: A vibration experimenting apparatus for education is provided to observe the measured signal through an ADC in real time by measuring a signal of a vibration system using a sensor. CONSTITUTION: A mass-spring system experimenting device(10) observes the movement of a rigid body according to the change of a frequency and the confirmation of a natural frequency of the rigid body. A vibration experimenting device(20) of a beam observes the movement of a cantilever according to the change of a frequency and the confirmation of a natural frequency of the cantilever. A vibration experimenting device(30) of a string confirms a natural frequency of the string and observes a mode shape according to the change of the frequency. A control box controls the experimenting devices.
