What is Transmissibility and how to calculate it in ASI Datalab?

What is Transmissibility?

Transmissibility is the ratio of output (Response) to input (Reference/Excitation). Generally, it means amplification & maximum amplification occurs when natural frequency and excitation/reference frequency of the system coincide. It measures the effectiveness of vibration isolating system. Lower transmissibility represents better isolation.

How to calculate Transmissibility in ASI Datalab?

Transmissibility can be calculated in time domain (RMS trends) or frequency domain (RMS Spectrum/Power Spectral Density).

To calculate Transmissibility in ASI Datalab following parameters are required as input:

RMS trend of response and excitation/reference signal.
Auto RMS Spectrum/ PSD of response and excitation/reference signal.
