PCT No. PCT/FR97/02293 Sec. 371 Date Aug. 11, 1998 Sec. 102(e) Date Aug. 11, 1998 PCT Filed Dec. 12, 1997 PCT Pub. No. WO98/26198 PCT Pub. Date Jun. 18, 1998A fixing arrangement with damping for fixing a device (1) to be protected from vibration, which device includes at least one mounting portion via which the device is fixed to a portion of a support (2) by fastening means (3, 4). The arrangement includes at least two piezoelectric elements (5, 6), each of which has its electrodes electrically shunted by an individual or shared impedance of determined structure. At least one of the elements (5) is used in bending and is interposed between a portion of the support and a mounting portion of the device to be protected. At least one of the elements (6) is used in compression and is interposed between one of the fastening means and either the support portion or the mounting portion.
