Vibration Isolation of Engine-Generator Sets Using InfiniSpring® Technology

InfiniSpring® technology has been successfully applied to reduce vibration in an internal combustion engine-generator set as part of the CASEMATE research project, led by the University of Oulu. By designing InfiniSpring® springs into the mounting system of a 1100 kg AGCO Power unit operated by Global Boiler Works Oy, the project demonstrated significant improvements in vibration isolation without modifying the original equipment. Simulation and measurement results confirmed high isolation efficiency across a wide range of operating speeds, paving the way for future innovations in resilient mounting solutions.
