LMS Test.Lab Rev 8

Share this on social media:

LMS has introduced LMS Test.Lab Rev 8 for noise and vibration testing and engineering. Rev 8 Test.Lab provides faster test preparation, efficient data acquisition, flexible processing, powerful reporting and transparent data sharing.

LMS Test.Lab Rev 8 introduces a new MIMO (Multiple Input Multiple Output) Sine Testing acquisition solution that uses stepped sine excitation technique to measure high quality FRFs, which allow the concentration of the excitation energy at a single frequency. The new LMS Test.Lab Stepped Sine workbook has been extensively validated in different testing assignments, including Ground Vibration Testing of a full aircraft, and several full-vehicle four-poster test rigs for vibration and acoustic comfort.

The newly introduced high-definition acoustic camera in LMS Test.Lab combines beam forming and focalisation methods to localise the sound sources on a structure. LMS Test.Lab visualises the sound fields through animation as a function of time and/or frequency, giving the user a clear indication of the acoustic hot spots.

The new sound intensity solution in LMS Test.Lab Rev 8 supports an easy definition and calibration of one or more intensity probes. It allows users to measure the pressure residual intensity index of the probe and to perform an online calculation of the residual intensity as a quality indicator of the measurement.
