Abstract:Launching vehicles undergo complex dynamic environment, and an ordinary vibration isolator cannot afford carrying the suppression of high-frequency vibration and avoid low-frequency vibration amplification. Using shape memory alloy (SMA) as a drive and metal rubber as damping elements, a novel design of vibration isolator was proposed. After experimental study on different parameters of the metal rubber, suitable metal rubbers were selected as the frequency tunable vibration isolator components. The experimental result shows that natural frequency of the frequency tunable vibration isolator can change from 60 Hz to 110 Hz, which meets the design requirements. © 2017, Editorial Office of Journal of Vibration and Shock.
