Title (EN) VIBRATION ISOLATOR DEVICE FOR A PERCUSSION TOOL
(FR) DISPOSITIF D"ISOLATION DES VIBRATIONS POUR UN OUTIL A PERCUSSION
Abstract: front page image
(EN)A vibration isolator device (10) is connected between a support member (72) and a percussion tool (14) having a distal work element (52) movable at a preselected vibratory rate. The vibration isolator device (10) includes a passive system apparatus (60) and an active system apparatus (62) for dynamically absorbing the transmission of vibratory forces from the tool (14) to the support member (72). The active system apparatus (62) includes a supplemental mass (88) and is actively tuned to the forces being applied to the tool (14) in response to a sensed system variable. Preferably, an accelerometer (122) is connected to a housing (46) of the percussion tool (14) to provide a sensed signal reflective of the disturbance force, and the active system apparatus (62) responds thereto to provide an opposition force to the supplemental mass (88).
(FR)Un dispositif d"isolation des vibrations (10) est connecte entre un organe de support (72) et un outil de percussion (14) ayant un element de travail distal (52) mobile a une vitesse vibratoire preselectionnee. Le dispositif isolateur de vibrations (10) comprend un appareil a systeme passif (60) et un appareil a systeme actif (62) pour absorber dynamiquement la transmission de force vibratoire de l"outil (14) vers l"organe de support (72). L"appareil a systeme actif (62) comprend une masse supplementaire (88) et est activement regle en fonction des forces appliquees sur l"outil (14) en reponse a une variable detectee du systeme. De preference, un accelerometre (122) est connecte a une enceinte (46) de l"outil de percussion (14) pour produire un signal detecte indiquant la force de perturbation, et l"appareil a systeme actif (62) repond a ce signal pour exercer une force opposee sur la masse supplementaire (88).
