PMSA-600
The plate vibration test kit allows visual observation of the mode shape directly at the natural frequency, so that the natural frequency of the structure and the corresponding vibration mode can be understood and the strength of vibration (displacement sensitivity) changes depending on the location of the structure. You will also learn the ability to find solutions to severe vibrations caused by resonance.
