Dynamics laboratory and Model Validation Facility

The Dynamics laboratory and the Model Validation Facility (MVF) are part of the Faculty’s advanced dynamic engineering facilities. Both laboratories are equipped with leading cutting-edge measurement and testing technologies to serve a large group of researchers with a focus on many aspects of dynamics, such as composites and nonlinear vibrations of mechanical structures.

Experiments on small to large structures or assemblies take place in the Dynamics laboratory. It is equipped with several measurement sensors, such as Laser Doppler Vibrometer (LDV) systems, both scanning and fixed point. Dynamic testing is very well served by a wide spectrum of electromagnetic shakers and piezoelectrics, which can cover from high to medium/low frequency bandwidth. The laboratory ceiling is equipped with heavy duty cranes, allowing movement of any type of test structure. Thanks to these capabilities, this is an ideal place for carrying out complex experiments and therefore enabling industrial partnerships from aerospace to defence industry.

The MVF is an annex of the main laboratory and is supported by Rolls-Royce plc. High performance experimental testing under stationary and rotating conditions takes place in this lab. It is equipped with dedicated SLDV systems, the largest electromagnetic shaker in the University, a sound booth, a unique contactless pulsed air-jet excitation system and a rotating test rig. Novel measurement techniques based on Continuous Scanning LDV measurement methods are available for performing experimental model validation. This laboratory cooperates in partnership with the Composites University Technology Centre for research in the areas of linear and nonlinear dynamics of composites under high strain rates.
