Abstract

The need to validate simulation models of complex mechanical structures continues to grow in importance to increase efficiency in the design process. This is especially true for nonlinear structures (such as composite panels and jointed components) where it is critical to use an accurate full-field measurement method. Multipath Doppler vibrometry (MDV) embodies the most recent breakthrough in dynamic characterization. It delivers high-quality vibration data consistently even for the most adverse environments and provides the test engineer with a reliable tool that is fast and easy to set up. The test object is measured in its unaltered form as it is not necessary to apply any surface treatments. MDV can be applied to a single point measurement and for 1D as well as 3D scanning vibrometry tests. The benefits are illustrated in this paper by various application examples.
