Experimental Modal Analysis

The purpose of modal testing is to determine the modal parameter. Modal parameter is resonance frequency, modal mass, modal damping ratio and mode shape of the structure and these parameters are calculated by curve fitting of transfer function which affects to the structure's dynamic behavior.

Modal Model

The modal test data is often used to create experimental modal model. By transferring modal parameters to modal matrix, experimental modal model can be processed in nastran analysis.
