A spring damper device comprising a directional spring (e.g., coil) having first and second ends, and defining an inner diameter region. A damper (e.g., viscoelastic polymer slug) comprising an element of elasticity configured to be situated within the inner diameter region of the directional spring. In response to a load on the spring damper device, the directional spring operates to compress, and the damper operates to dampen vibration associated with the load. The damper can comprise a viscoelastic damper comprising both an element of viscosity and the element of elasticity. The damper can be substantially coaxially aligned with the directional spring. Spring damper device(s) can be preloaded in a micro adjustment mechanism to account for positional adjustments between two structures (e.g., between a scope and a firearm), such that the spring(s) attenuate a shock impulse event (e.g., when firing), while the damper(s) attenuate vibration (e.g., to prevent damage the scope).

The present disclosure provides a body structure for a vehicle capable of improving a vibration damping effect by a damping member while preventing an increase in an application amount of the damping member and a shape change of a component. Embodiments include a body structure for a vehicle in which a first bonded surface of a first body component and a second bonded surface of a second body component are bonded via a damping member, with which a portion between the first bonded surface and the second bonded surface is filled. The first bonded surface of the first body component has a vertical wall extending toward the second bonded surface or away from the second bonded surface. The portion between the first bonded surface and the second bonded surface is filled with the damping member such that the damping member contacts the vertical wall.

A seismic isolation structure using a rope foundation of the present invention is to separate and support an object from a ground at the same time. The seismic isolation structure may include a base positioned on the ground and provided with an accommodating space with an opened upper portion and two or more rope supporters spaced apart around an entrance of the accommodating space, a support including a stage for supporting an object, and a column protruding downward from the stage and positioned in the accommodation space, and ropes connecting the rope supporter and the lower part of the column to support the support to be spaced apart from the base.

A culture apparatus includes an inner box for housing a culture, an outer box surrounding the inner box, and a first vibration prevention mechanism that is disposed between the inner box and the outer box, and is configured to prevent the inner box from vibrating due to the vibration of the outer box.

A passive oscillation damper (8), in particular for a switch cabinet (2), includes a supporting structure (12) having a longitudinal direction (y) and a transverse direction (x) and with a central oscillating mass (14) mounted by means of spring elements (20, 22, 24, 26) so as to be able to oscillate in the longitudinal direction (y) and in the transverse direction (x). At least one peripheral oscillating mass (40, 42) is mounted on the central oscillating mass (14) so as to be slidable in the longitudinal direction (y) and to be movable relative to the central oscillating mass (14). At least one peripheral oscillating mass (44, 46) is mounted on the central oscillating mass (14) so as to be slidable in the transverse direction (x) and to be movable relative to central oscillating mass (14).

A locking isolator includes one or more joints. The one or more joints are configured to transition between a clearance fit state and an interference fit state in response to a change in temperature. The locking isolator includes a dampener. The dampener is configured to attenuate transmission of vibration through the one or more joints when the one or more joints are in the clearance fit state.
