Classical modal analysis
In classical modal analysis, a model of a structure’s dynamic properties is obtained by exciting the structure with measurable forces and determining the response/excitation ratio.
Classical modal analysis ranges from simple mobility tests with a roving impact hammer and a fixed accelerometer to multi-shaker testing of large structures using hundreds of accelerometers. It is used in a vast range of tests including design verification and optimization, certification testing, troubleshooting and benchmarking.
Our classical modal analysis solutions guide you through the complete set-up, measurement and analysis in simple and intuitive steps, and provide you with accurate and reliable results even in the most demanding situations, with a targeted set of best-in-class modal parameter estimators and validation tools.
Our solutions cover the entire measurement and analysis chain including accelerometers and force transducers, impact hammers, modal exciter systems, LAN-XI data acquisition hardware and BK Connect® software for pre-test analysis, measurement, analysis and Finite Element model correlation. Our solutions are also expandable so they can grow with your requirements.
