LMS Test.Lab Structures

Straightforward structural dynamics and modal testing

LMS Test.Lab Structures is a comprehensive suite of structural dynamics and modal testing and analysis software. Characterizing the structural dynamics of a structure used to be a long and complex process involving quite extensive trial-and-error and time-consuming test setups. This is no longer the case. With LMS Test.Lab Structures and the LMS SCADAS system, it’s easier to perform large-scale modal surveys – in hours rather than days.

You can focus on identifying root causes of vibration problems and apply powerful analysis tools to explore the best solution for practically every structural weakness. Our modal testing experience – from impact testing of small structures to large-scale campaigns using hundreds of measurement channels, helps you maximize testing efficiency.

Impact Testing

LMS Test.Lab Impact Testing provides you with a complete solution for modal testing using an impact hammer. The solution’s range of capability allows roving hammer with fix accelerometer or fix hammer point with all accelerometers on the structure for frequency transfer function measurement for either experimental modal analysis or transfer path analysis.
