Vibration analyses
A variety of vibration analyses can be carried out in the H-BRS dynamics laboratory. An electrodynamic shaker with a maximum payload of 150 kg is available for vibration excitation. Vibration analysis is carried out either classically via acceleration measurement and modal analysis in order to analyze the movement patterns in various resonance states or via optical 3D measurement using a high-speed camera.
Accompanying measurement tasks and load simulations
The loads can also be measured using strain gauges. Most of the available measuring equipment can also be used as mobile equipment for external measuring tasks. Typical tasks that have been dealt with so far are the identification of noise sources, investigation of the transmission behavior of materials, analysis of movement patterns that are not visible to the naked eye, as well as load simulations and analysis of the long-term effects, for example for electronics or plastic components.
„Anything that vibrates, squeaks and rattles is unpleasant for people and, in case of doubt, means unnecessary stress and wear for the machine. We help with the investigation of vibration behavior, the search for weak points or the analysis of suitable components that can withstand or prevent vibrations.”

Industrial services
In the field of industrial services, we receive inquiries from customers ranging from small companies to large corporations in the automotive, computer and electrical engineering and rubber industries. Please do not hesitate to contact us if you have specific research ideas or need support with entrepreneurial challenges. With vibration testing systems of various sizes, laser vibrometers and a high-speed camera system that can optically record the deformation of components under load, we are ideally equipped to analyze dynamic load cases. For example, the functioning of digital and electrical components under various vibration loads was investigated. Other examples of practical and model computer simulations include noise analyses on drive trains of cars and agricultural machinery, as well as the determination of the damping properties of rubber parts and the development of test methods to determine the sound insulation properties of entire cars. Individual analysis tools can be developed and implemented for the damage assessment of test parts. Off-site measurements for larger or fixed components and machines for vibration analysis are also possible.
