Description
Experimental Modal Analysis (EMA) is an extremely useful Root Cause Analysis & Defect Elimination (RCA&DE) technique, which helps CBM practitioners in solving many Plant problems by identifying natural frequencies, damping coefficients, and mode shapes of the vibrating machine trains or mechanical structures. When it is known that the excitation force coincides with one of the natural frequencies found in the modal analysis, the structure or machine foundation could be redesigned or modified to shift the natural frequency away from the excitation frequency. Structural elements can be added in order to increase the stiffness of the structure or mass can be increased or decreased. Other approach could include increasing the damping of the structure by changing the material or adding viscoelastic material to the surface of the structure.
