20080246199 | Hydraulic bearing with biaxial damping - The invention is directed to a hydraulic bearing with biaxial damping with an axial and radial damping characteristics which can be defined essentially independent of one another. The hydraulic bearing consists of a housing and an axially and radially operating elastomeric damping arrangement received in the housing. The damping arrangement has several chambers adapted to receive a hydraulic damping means and formed, with respect to the axial and radial orientation of the bearing, in pairs, with each chamber pair interconnected by at least one channel. The upper housing section is constructed as a support body consisting of an inner core, and the outer wall of the upper housing section radially separated from the inner core, and a spring connected with the inner core and the outer wall by vulcanization. According to the invention, the hydraulic bearing has a modular construction, wherein the chambers affecting the radial damping are part of a bush bearing which is inserted in the support body as a separate component and non-positively and/or positively connected thereto. | 10-09-2008 |
20080251981 | Torsional Vibration Damper - The invention relates to a torsional vibration damper with a flexible coupling ( | 10-16-2008 |
20090273127 | HYDRAULICALLY DAMPED BODY MOUNT WITH BOLT-THROUGH CONSTRUCTION - A mount has an inner metal and an outer metal with an elastomeric bushing disposed between them. The elastomeric bushing includes a first pair of interconnected passages to control the damping rate during axial motion and a second, separate pair of interconnected passages to control the damping rate during motion orthogonal to the axial direction. | 11-05-2009 |
20100032876 | VIBRATION ISOLATOR SYSTEM - A vibration isolator system for attaching a payload to a supporting base is provided, the payload having a center of mass and the system consisting of at least three vibration isolating pods. Each pod has two associated, non-parallel, elastic struts. A first end of each strut is attached to the supporting base and a second end of each strut is attached to the payload at a respective mounting point, and the a projected elastic center of the system is substantially co-located with said center of mass. The vibration isoloator system is operable to substantially prevent translational vibration of the supporting base from inducing angular rotation of the payload. | 02-11-2010 |
20100078863 | ATMOSPHERIC TURBULENCE ISOLATION SYSTEM AND METHOD - A vibration isolation assembly for an aerodynamic object comprises a viscoelastic inner layer disposed on the aerodynamic object and being configured to attenuate vibration. The vibration isolation assembly further comprises a rigid or stiff outer layer disposed on an inner layer. The vibration isolation assembly may attenuate the transmission of aerodynamically-induced vibration to components contained or mounted to the aerodynamic object. | 04-01-2010 |
20100133733 | VIBRATION DAMPER, PARTICULARLY FOR SUPPORTING COMPRESSORS, PUMPS, ELECTRIC MOTORS AND THE LIKE - A vibration damper, particularly for supporting compressors, pumps, electric motors and the like, comprising a flat body from which at least two engagement tabs protrude on each of the two faces and at least two elastically deformable contact and shock-absorbing portions protrude on at least one of the faces. | 06-03-2010 |

20120326366 | VIBRATION ISOLATION STRUCTURE - A vibration isolation structure is provided with a stress reduction section that can reduce the hydrostatic stress from tensional load along a stacking direction of portions of a composite laminated member corresponding to a first end side and a second end side in a shear direction orthogonal to the stacking direction to lower than the hydrostatic stress from tensional load along the stacking direction of other portions of the composite laminated member. | 12-27-2012 |
20130241123 | STRUCTURE THAT CAN CHANNEL AN ELASTIC WAVE PROPAGATING IN A PLATE - A structure for bending transversal elastic waves around a zone to isolate of a plate, has an anisotropic Young's modulus and/or a heterogeneous mass density. The wavelengths of the elastic waves to bend are large with respect to the thickness of the plate and small with respect to the other dimensions of the plate. The structure is made by defining a meshing of a peripheral zone surrounding the zone to isolate; dividing the peripheral zone into several elementary rings and several elementary angular sectors; and forming, in each mesh delimited by an elementary angular sector and an elementary ring, a structural element in a material having a Young's modulus and/or a mass density different than those of the material forming the plate, the dimensions of the meshes and of the structural elements in the plane of the plate being less than half the wavelengths of the elastic waves to bend. | 09-19-2013 |
20140048989 | VIBRATION ISOLATION SYSTEMS - A composite vibration isolation system utilizes isolators with negative-stiffness mechanisms to produce low vertical and horizontal natural frequencies to the system by allowing both the horizontal stiffness and horizontal natural frequencies to be adjusted, for example, by turning adjustment screws. | 02-20-2014 |
