Experimental Modal Analysis Operational Modal Analysis Operational Deflection Shape Instrumentation Applications Contact Us Home > Experimental Modal Analysis Experimental Modal Analysis Experimental Modal Analysis (EMA) is an effective instrument for describing, understanding and modelling the dynamic behaviour of a structure. It can be carried out both to determine the natural frequencies and mode shapes of a structure and to verify accuracy and calibrate a finite element model (FE). Also, the EMA can be used in order to make a troubleshooting vibration problems. Thanks to the best specialized softwares, SINT can carry out the PRE-TEST analysis (in order to chose the best set-up measurement) and the CORRELATION analysis (for the comparison of the Finite element model with the experimental model). SINT Technology can determine the main modal parameters: Natural frequencies Mode shapes Damping The validation of the modes is done using the following: Modal Assurance Criterion (MAC) Complexity tools Modal Phase Collinearity (MPC) Mean Phase Deviation (MPD) Phase scatter Some examples of the experimental modal analysis techniques that SINT Technology can use are: Impulse excitation (instrumented hammer) Controlled excitation (shaker) Operational Modal Analysis (OMA) Operational Deflection Shape (ODS) Experimental Modal Analysis standards ISO 7626-2 Vibration and shock - Experimental determination of mechanical mobility - Part 2: Measurements using single-point translation excitation with an attached vibration exciter ISO 7626-5 Vibration and shock - Experimental determination of mechanical mobility - Part 5: Measurements using impact excitation with an exciter which is not attached to the structure SINT Technology srl Via delle Calandre, 63 50041 Calenzano (FI) - ITALY tel: +39.055.8826302 - fax: +39.055.8826303 info@sintechnology.com VAT n.
