Modal Analysis Software vModal Modal Analysis SDOF local, global MDOF local, global Mode-Indicator Function Synthetic FRFs Free Viewer No engineer could possibly manage to design a construction, solving all problems due to noise and vibrations without precise knowledge of the inherent properties of a structure. To determine the structure's properties experimentally the modal analysis offers an excellent tool. vModal provides the engineer with the complete hard- and software equipment necessary to carry out a successful modal analysis or an operating deflection shape measurement. Signal Analyer The vAnalyzer is integrated in vModal. The vAnalyzer is a complete vibration measurement system that supports different DAQ hardware. Devices from 4 to 64+ channels are available as USB or Ethernet solutions with frequency ranges from 1Hz to 100kHz. Measurement Data Every measurement will be transferred via the measurement interface to the database. From there they can be recalled for any displaying and editing. Further the measurement interface includes the routines for modal extractions of multi-shaker measurements. UFF Import for external data Data from external DAQ systems can be imported as UFF-Files.

Modal Calculation For the determination of the modal-Values and for other calculations the following functions are available:         SDOF local, global MDOF, local, global Hand-fit Mode-Indicator Function Poly Reference Synthetic Frequency Response Functions Fit Quality Function MAC Function Simulation Using the results of the modal analysis, Eigen-frequencies, mode shapes and damping, the engineer will be able to create a mathematical model, suitable for any calculation concerning sensitivity and optimization. A feature to carry out forced response calculations is also integrated. Verifications...
