Perform measurement of allowable residual unbalance
After a balance adjustment, the vibration displacement is measured and taken as the residual unbalance.
Measure the damping ratio of resonating machinery
Using an accelerometer and single-channel FFT analyzer, the attenuation waveform of the vibration after excitation is measured and the one-degree-of-freedom damping ratio is determined from the result.
Determine transfer function and natural frequency
To measure the transfer function, an impulse hammer and accelerometer as well as a 2-channel FFT analyzer are required.
Measure the loss factor of an object
Using the SA-02 system, the loss factor of a material can be measured, using either the center excitation method or the cantilever method.
