LMS Test.Lab Modal Analysis

LMS Test.Lab Modal Analysis offers various fast and accurate single or multiple reference parameter estimation algorithms. The FRFs are gathered and automatically organized to give a comprehensive view of the available data and facilitate FRF selection/de-selection. Various sum and mode indicator functions help stabilization diagram interpretation and pole selection. The solution offers a complete set of modal model validation tools. The scrolling FRF synthesis automatically synthesizes FRFs and updates displays, without any user interaction, for fast and in-depth modal model validation.

LMS Test.Lab Modal Analysis provides all the tools and functions required for experimental modal analysis. It includes tools to easily create FRF sets, perform modal parameter estimation in a fast and easy way on these FRF sets, validate the modal model using different methods and compare the original FRFs with synthesized ones. A worksheet-by-worksheet procedure guides the user through the basic steps. 

For multiple patch measurements, the multi-run modal analysis provides an easy method to solve potential data inconsistency issues between patches. Multi-run modal analysis provides a dedicated processing of modal test data that was obtained through different sets of measurements. This acquisition technique is widely applied when a limited set of accelerometers needs to be relocated to measure all response points of the structure. In such a case, FRF inconsistencies could affect the modal parameter estimation quality. Multi-run modal analysis automatically accounts for potential data inconsistency between runs when extracting modal frequencies and damping as well as during the subsequent mode shape calculation.

For complex structures, LMS Test.Lab PolyMAX provides a state-of-the-art modal parameter estimator and expert-like automatic modal pole selection (AMPS) facility. Combination of these tools provides fast and user-independent results. LMS Test.Lab PolyMAX is available as an add-in to LMS Test.Lab Modal Analysis.
