Researchers at ETH Zurich have developed a lattice structure capable of absorbing a wide range of vibrations while also being useful as a load-bearing component – eg, in propellers, rotors and rockets. It can absorb vibrations in the audible range, which are the most undesirable in engineering applications. Vibrations from the propellers or rotors in propeller aircraft and helicopters can make the flight bumpy and loud, and also lead to increased fatigue damage of the aircraft and its components. A new 3D lattice structure developed by ETH scientists could now expand the possibilities of vibration absorption.
