The universal vibration test apparatus (UVT-1000) is the test equipment for measurement of the natural frequencies and mode shapes of structures such as beam, plate, mass-spring system, pendulum and string vibration. The concept of vibration mode at natural frequency can simply be understood by the observation with the unaided eye and compared the results of the theoretical vibration analysis in a comprehensive way.
