Abstract: A liquid-sealed vibration damping device is provided that allows an outer cylindrical member to have a substantially uniform interference margin in the circumferential direction, while improving an assembling property. A second mounting member mounted on a non-vibration source includes: a first frame in a cylindrical shape that is connected to a lower portion of an insulator; a second frame in a cylindrical shape that holds a partition member arranged below the insulator; and a connector that connects the first frame with the second frame. The connector includes: engaging parts that are arranged on the first frame; and elastic hook parts that are arranged on the second frame. The elastic hook parts are arranged at intervals on each of main frame parts in the circumferential direction thereof, and the elastic hook parts arranged on corners have lower rigidity than those arranged on the main frame parts.

Abstract: A vibration isolator (10) includes a first attachment member (11), a second attachment member (12), an elastic body (13), and a partition member (16) configured to partition a liquid chamber in the first attachment member in which a liquid (L) is sealed into a first liquid chamber (14) and a second liquid chamber (15). A communicating passage (30) configured to communicate the first liquid chamber with the second liquid chamber is provided in the partition member. A flow changing protrusion (31) is provided at an inner circumferential surface (30a) of the communicating passage. A guide surface (32) opposite to the communicating passage and intersecting the axial direction (O) of the communicating passage is provided at the flow changing protrusion. A passing hole (34) which is open toward both sides in the axial direction is formed by a projecting end (31b) of the flow changing protrusion and another place on the inner circumferential surface (30b) of the communicating passage. The flow changing protrusion changes the flow of the liquid flowing in the communicating passage and reaching the guide surface toward the projecting end. The guide surface is formed in a concave curved surface shape which is recessed in the axial direction.

Abstract: An anti-vibration device has excellent durability while reducing the amount of elastic deformation of an elastic body to a desired value. The disclosed anti-vibration device (1) includes an inner member (2), an outer member (3), an elastic body (4) that allows relative displacement between the inner member (2) and the outer member (3), a pair of first fluid chambers (C1) in communication with each other via first restricting passages (r1), and a second fluid chamber (C2) in communication with an auxiliary fluid chamber (C3) via a second restricting passage (r2). The first fluid chambers (C1) are disposed at opposite sides of the inner member (2). The second fluid chamber (C2) is disposed in an orthogonal direction (Z) that is orthogonal to a sandwiching direction (Y) and to a direction along the axis (O) of the inner member (2). Stopper parts (S) are provided in the first fluid chambers (C1).

Abstract: A system for mitigating vibration of a mass may include an elastic membrane enclosing at least one interior space and having an outer surface, where at least a bottom portion of the outer surface is coupled to a transportable supportive surface, and at least a top portion of the outer surface supports a load. The system may further include at least one port coupling the outer surface to the at least one interior space, where the port provides a source of fluid ingress into the interior space and fluid egress out of the interior space. The system may additionally include granular material distributed within the at least one interior space, where a packing density of the granular material is adjustable between a first jammed state having a first packing density of granular materials and a second jammed state having a second packing density of granular materials to accommodate different loads.
