Abstract: Broadband particulate absorbers include a suspended container for containing particulate beads that absorb vibration energy over a broad bandwidth so reduce coupled vibrations of mechanical systems over the broad bandwidth. The absorbers preferably include two opposing aluminum containers for containing particulate teflon beads. The aluminum containers are suspended and separated by aluminum I-beams attached to stringers of a rocket subjected during lift off to atmospheric pressure vibrations exerted on the vehicular skin coupling vibration through the stringers to trusses supporting sensitive inertial navigation payloads. The absorbers can be finely tuned using variably thick mass or various amounts of beads for reducing peak vibrations coupled into the payloads.

Abstract: The damped structural member includes a structural member and granular material in intimate contact with the member. In one embodiment the granular material is lightweight and has a bulk specific gravity of less than 1.5. When low weight is important, the granular material has a bulk specific gravity of less than or equal to one. The particles of the granular material are also in intimate contact with one another. The granular material may be substantially non-viscoelastic. Preferred granular material is low density polyethylene and glass microspheres. The granular material fills hollow structural members or is placed into intimate contact with open structural members. The lightweight fill effectively damps vibrational modes without excessively increasing the weight of the structural member.

Abstract: A triaxially-equalized action shock and vibration-insulation mount is provided for the protection of a dynamic load-sensitive component, such as a mass-storage device, from external multidirectional dynamic loads above a predetermined magnitude. A substantially uniform, attenuated response of the component to such dynamic loads is the result, regardless of the direction of application of the loads. In order to achieve substantially uniform reactions to such external loads applied along any of the three orthogonal spatial axes, and further in order to achieve higher structural integrity of the mount by reducing flexural, tensile and/or shear stresses, the shock mount comprises a body of elastic, preferably foamed elastomer material, which is confined at its periphery in a rigid, stationary shell, substantially symmetrical relative to the orthogonal spatial axes and partially open at one side. The elastic material body is shaped at its geometrical center to provide a tight, e.g., spherical, socket for an enlarged symmetrical, e.g. spherical, end portion of a rigid rod extending outward from said socket, through the partially open side of the shell, into rigid connection with the load-sensitive component. The elastic material of the body is stressed primarily in compression along each of its axes. The elastomeric material may alternatively be constituted by a plurality of relatively small-diameter tightly randomly packed, solid elastic spheres.

Abstract: A self-adjusting shock absorbing carrier for inverted powder and free conveyors includes a telescoping tubular main carrier frame with a support trolley connected to a rear end of an outer tube and a drive trolley connected to a front end of an inner tube of the frame. Tubular friction pads are positioned between the inner and outer tubes and located so that the weight of a load supported by the main frame determines the frictional engagement between the inner and outer tubes and the friction pads. When the drive trolley is abruptly engaged by a pusher dog on a conveyor drive chain or when the drive trolley is abruptly braked, the shock generated thereby is dissipated in frictional resistance to relative movement between the inner and outer tubes to thereby cushion startup and braking of the carrier.

Abstract: There is provided a new improved dampening medium for a shock dampening device. The dampening device comprises a closed chamber, a movable piston rod extending through the chamber and an enlarged piston head located on the piston rod. Located in the interior space of the closed chamber under pressure is a compressible solid, fragmented, particulate mass of cured unfilled silicone rubber composition for producing a damping effect on the piston rod and head. The damper device includes a threaded plug for varying the internal static pressure on the compressible mass within the chamber and apertures extending through the piston head or an annular space between the outer edge of the piston head and the interior of the chamber for bypassing the compressible mass.

Abstract: A particle damping assembly designed provides enhanced vibration control, especially for use with sound systems. The assembly comprises a housing encompassing multiple containers. Each container is designed to hold particles of varying sizes that contribute to the particle impact damping effect, offering improved sound quality by mitigating unwanted vibrations.

Abstract: Systems and methods for reducing vibration in downhole tools using particle dampers. In one embodiment, an ESP system has components including at least a pump and a motor. The motor is coupled to the pump and is configured to drive the pump to pump fluid from a well. The ESP system also includes a particle damping unit which is mechanically coupled to at least one of the ESP components. The particle damping unit has one or more compartments, each of which contains a collection of particles that are loose within the corresponding compartment. Vibration in the ESP components causes movement of the particles within the compartments of the particle damping units, and the movement of the particles dissipates the vibrational energy, causing damping of the vibration.
