ME´scope Modal Analysis

ME'scope post-test analysis tools allow you to observe, analyse and document the dynamic behaviour of machines and mechanical structures. ME'scope is MS Windows-based software and includes options for performing operating deflection shape analysis, modal analysis, multiple input/output (MIMO) analysis and structural modifications.

ME'scope is capable of both time domain and frequency domain animations. By animating the measured responses (operational deflection and mode shapes) of a structure in slow motion, you recieve a unique perspective of the structures dynamic behaviour. Operating deflection shapes or mode shapes can be stored in a Shape table. Analytical mode shapes from a finite element model can be imported into a Shape table and compared with experimental results. Shapes can be compared analytically using the Modal Assurance Criterion (MAC) or by displaying them together in animation. ME'scope provides more realistic animated pictures of a structure's deformations from relatively few measurements using measurement point interpolation. The motions for all unmeasured points on the model are interpolated from motions at neighbouring measured points.

Using the ME'scopeMODAL or ME'scopeSDM options, experimental modal data (frequency, damping and mode shape) is obtained by curve fitting a set of FRF measurements. ME'scope contains three built-in curve-fitting methods: Quadrature Fit, Peak Fit, Rational Fraction Polynomial, Complex Exponential Single as well as Multi degree of freedom. The curvefitters can be used to curve fit single or multiple reference FRF data sets.
3D model building, display, and interactive animation features along with Digital Movies™ are standard in all ME'scope solutions.
