A tuned mass absorber assembly comprises a mass structure, and a flexure system comprising first and second flexure sections (e.g., cross bar flexures) supported by, and extending in opposing directions from, the mass structure. The flexure system can comprise flexure section mounts situated at distal ends of the first and second flexure sections, respectively, and that are operable to mount the tuned mass absorber assembly to a structure subject to induced vibrations therein. A mass of the mass structure and a stiffness of the flexure system can be tuned to attenuate vibrations at a specific input frequency generated in response to induced vibrations of the structure. A system can comprise a vibration isolator attached to a chassis (e.g., of an airplane), and supporting a payload (sensors(s)) and isolating the payload from vibrations. A tuned mass absorber assembly can be mounted to the vibration isolator for attenuating vibrations at a specific input frequency that may affect the payload.

An apparatus for damping a first member relative to a second member. The apparatus includes a receiving member that includes a flange, an axial elastomeric member, and a radial elastomeric member. The axial elastomeric member is positionable between a surface of the first member and the flange of the receiving member, and the radial elastomeric member is positionable between the first member and the receiving member.

A vibration isolator comprises: a first member in which an end portion of a shaft portion being fixed to a mating member; a vibration-isolation base made of an elastic body connecting a second member and the first member; and a stopper made of an elastic body arranged between the second member and the mating member with the first surface. The shaft portion is arranged in the hole of the stopper with the end portion facing the matching member. The inner surface of the hole of the stopper, prior to the shaft portion is inserted into the hole, includes: a first portion having a span smaller than the thickness of the end portion of the shaft portion; and a second portion arranged between the first portion and the second surface. A span of the second portion is greater than the span of the first portion.

Damping stopper for a mechanism in which a housing and shaft are not only displaced axially relative to each other but but also rotated relative to each other. The damping stopper is attached to a space portion between an end surface portion on housing side and an end surface portion on shaft side which is displaced axially relative to the housing and is rotated relative to the housing and has a metal fitting on one of the end surface portions, an elastic body connected to the metal fitting, and a sliding member connected to the elastic body. The sliding member contacts the other end surface portion to contact/separate from the other end surface portion and the sliding member is slidable and rotatable relative to the other end surface portion when the shaft is rotated while the sliding member, containing resin component, contacts the other end surface portion.

A bearing bush for supporting a motor vehicle part includes an inner tube made of a metal, a sliding sleeve made of a first plastic material and mounted rotatably on the inner tube, and an elastomer bearing which surrounds the sliding sleeve and has at least a first elastomer body and an outer sleeve. A sliding layer made of a second plastic material is applied to an outer circumferential surface of the inner tube, the first plastic material and the second plastic material forming a tribological pairing either of two different polymers from the groups of polyamides, polyoxymethylenes, polyketones, fluoropolymers, polyethylene terephthalates or polybutylene terephthalates, or the tribological pairing being formed from polyketone against polyketone, wherein the polymers of the tribological pairings each are present in a continuous thermoplastic polymer phase.

A bushing assembly for use in a vehicle suspension system includes an outer sleeve, with an elastomeric element at least partially positioned within the outer sleeve. An inner sleeve is at least partially positioned within the elastomeric element, while a bar pin having a central section is at least partially positioned within the inner sleeve. A retaining ring is positioned at or adjacent to a first end of the central section of the bar pin and at least partially within the outer sleeve. The retaining ring is positioned between the inner sleeve and at least one radially enlarged section at the first end of the central section of the bar pin and/or at least one radially inwardly directed section at a first end of the outer sleeve.

Equipment including an inertial detector device provided with fastener studs enabling the inertial device to be fastened to a support frame. At least one of the fastener studs has two elements, one of which elements is fastened to the support frame and has a bearing surface that is in contact with a bearing surface of the support frame. The other element is fastened to the inertial device and has a bearing surface that is in contact with a bearing surface of the inertial device, which two elements are suspended relative to each other by means of a body made of elastically deformable material. At least one of the elements is fastened by at least one screw. The corresponding bearing surfaces is provided respectively with a centering portion and with a housing for receiving said centering portion with a fit that allows clearance of no more than 50 m.

An apparatus for damping a first member relative to a second member. The apparatus includes a receiving member that includes a flange, an axial elastomeric member, and a radial elastomeric member. The axial elastomeric member is positionable between a surface of the first member and the flange of the receiving member, and the radial elastomeric member is positionable between the first member and the receiving member.

The silent block comprises a pipe (2) around the circumference of which rubber (1) is arranged, a casing (4) being arranged on at least a substantial portion of the outer circumference of the rubber (1). The casing (4) is divided into at least two separate parts in the axial direction. On the contact surfaces between the casing (4) and rubber (1), at least one outer protrusion (5) is arranged on one of the contact surfaces that fits into at least one opposite outer recess (7) arranged in the other contact surface.

A vibration isolator comprises: a first member in which an end portion of a shaft portion being fixed to a mating member; a vibration-isolation base made of an elastic body connecting a second member and the first member; and a stopper made of an elastic body arranged between the second member and the mating member with the first surface. The shaft portion is arranged in the hole of the stopper with the end portion facing the matching member. The inner surface of the hole of the stopper, prior to the shaft portion is inserted into the hole, includes: a first portion having a span smaller than the thickness of the end portion of the shaft portion; and a second portion arranged between the first portion and the second surface. A span of the second portion is greater than the span of the first portion.
