The Noise and Vibration Research Group of the department of Mechanical Engineering of the KU Leuven is a section of mechanical engineering department named LMSD ([Leuven] Mecha(tro)nical System Dynamics) and has a well-established research experience in the field of noise and vibration analysis of mechanical structures. Machine tool stability was the origin of the research in the field of structural dynamics at LMSD (formerly known as PMA). In 1973 LMSD was one of the first laboratories in Europe to introduce a digital FFT Analyser (HP 5451A) for noise and vibration analysis in the field of mechanical engineering.

The development by LMSD researchers of analysis methods (modal analysis) to characterise and optimise the structural dynamic behaviour raised the interest of several European industries and research institutes. Challenging and important research projects followed, giving LMSD worldwide recognition in the field of noise and vibration analysis.

Some spin-off companies were founded by former LMSD collaborators to commercialise the results of LMSD's structural dynamics research. The most successful among them is certainly Siemens PLM Software which evolved throughout the years to become a market leader in the field of noise and vibration analysis software. The close collaboration and joint research projects between LMSD and Siemens PLM Software are certainly a guarantee for the industrial relevance of the scientific research at LMSD, and offers a unique forum for its research results.
