For modelling or to analyze the dynamic behaviour of a structure, it is important to measure the dynamic characteristics of the structure. | |||

| Modaal Analyse, Modal Analysis, Structural Vibrations, Dynamic behavior | ||

| To measure and to calculate the frequencies, damping and mode shapes of a structure. Setups are: Time domain, FFT spectrum, Auto-spectrum, Cross-spectrum, FRF functions, Coherence and Power spectra. In the Modal Analysis package it is possible to measure the Operation Deflection Shapes, and to calculate the Modal Model. | ||
