Employing Hydraulic Transmission for Light Weight Dynamic Absorber

The absorber is built out of a double-sided piston of cross section connected by elastic elements (spring, beam, ...) to the vibrating structure. Both piston sides communicate due to a closed loop pipe of cross section and length . Due to the piston movement the fluid mass is accelerated. The piston movement and the fluid movement is geared by the factor . With this transmission factor the effective absorber mass is given .
