Vibration and Smart Structures lab

Image 1 of 1

The laboratories Vibration and Smart Structures lab are used both for research and educational purposes. Research topics investigated in the labs cover a wide range of vibration related subjects, from calibration and validation of computational models to measured data to energy harvesting, with applications within wind power and automotive industries, for example.

Vibration laboratory

The vibrations lab holds several data acquisition systems, some readily mobile and others rack mounted, used to measure accelerations, forces and strains over time. Data from such measurements are used e.g. for identification of sources of vibration and fatigue and to calibrate computational models. Applications served are the railroad, automotive, metal cutting and wind power industries, and experiments are equally likely to be performed in the lab as at the machine, sleeper pad or train set exhibiting problems.

Smart structures lab

In many ways, the equipment in the smart structures lab resembles that of the vibration lab, but the focus here is instead to minimize vibrations through active/semi-active damping. The smart structures lab also holds a scale model of the drive line of a wind turbine plant, set up to study the effects of wear on bearings caused by such things as axial misalignment.
