Partnering with Denmark’s Structural Vibration Solutions A/S, Dewesoft now offer a powerful yet easy-to-use Operational Modal Analysis (OMA) solution. SVA’s ARTeMIS OMA software has been integrated with Dewesoft X software, allowing full set of modal parameters to be estimated for structures when only output response data has been acquired.

OMA is used for large civil engineering structures, operating machinery, or other structures that have natural loads that cannot easily be controlled and measured, such as wind loads on buildings, traffic loads on bridges and wave loads in offshore wind turbines.

With Dewesoft X and the ARTeMIS OMA plugin option, parameters can be estimated for mode shape, natural frequency, and damping ratio.

Unlike ODS (Operating Deflection Shapes), OMA identifies and separates noise and inputs from the output data and returns the unbiased modal information only. This allows the estimation of modal models from the operational data. OMA is also referred to as output-only modal analysis, ambient response analysis, ambient modal analysis, in-operation modal analysis, and natural input modal analysis. Dewesoft X software also supports ODS, sine processing and a wide range of related modal applications, so it is a one-stop solution.

Engineers can important Dewesoft X data files directly into the Dewesoft ARTeMIS OMA application and run the analysis. Dewesoft X and ARTeMIS is a one-time purchase. Customers get product licenses with no expiration date, no maintenance fee or other yearly fees. https://dewesoft.com/products-news/dewesoft-artemis-oma
