A vehicle vibration damper assembly may include a bracket, a canister, and steel shot. The bracket is for mounting to an engine compartment rail in mechanical contact with an engine. The canister is mounted to the bracket and defines a cavity. The steel shot is disposed within the canister in an amount selected to reduce an amplitude of a vibration of the engine during operation. The bracket may be mounted to an engine compartment rail. The bracket may be secured proximate an engine compartment rail such that the canister is mechanically connected to the engine. The amount of the steel shot may be such that energy generated by the engine during operation is dissipated into heat energy or impact energy by the steel shot.

A vibration damping counterbalance unit for an inceptor apparatus having a wall defining a cavity; and a plurality of vibration damping masses housed within the cavity.

According to certain embodiments, a vibration-isolating case comprises a resilient, plastic-composite walled case and vibration-damping footing located at the bottom side of the case. Each vibration-damping footing comprises a mounting plate, cushions, and a damping system. The mounting plate has a flat surface and side surfaces extending from the flat surface to form a channel-shaped structure. The flat surface is positioned proximate a bottom outer surface of the case and couples to at least one brace within the case. The cushions are positioned within the channel-shaped structure such that the side surfaces of the mounting plate protect at least a top portion of each cushion. The damping system is positioned between the cushions and comprises a tray containing a quantity of inelastic particulate. A mechanical path exists between the vibration-damping footing and a platform mounted within the case.

An apparatus for optimizing vibration attenuation of a printed circuit board (PCB) by means of a tunable control for adjusting the volumetric storage capacity, effective mass and travel displacement of a particle impact damper (PID). The apparatus is comprised of a housing with a single or plurality of sealed storage tank(s) containing a payload of tungsten balls (or other materials) with a single or plurality of adjustment screw(s). The volumetric capacity of the storage tank is at maximum when the screw is fully withdrawn from apparatus. The volumetric capacity of the apparatus is reduced when the screw is inserted into the storage tank. The tunable adjustment screw controls the performance of the PID to dampen and attenuate (reduce) the vibration in a printed circuit board without the need to add or remove the payload of tungsten balls inside the particle impact damper.

A vibration damping component for a vehicle includes a housing, and a mounting lug attached to the housing. The mounting lug includes an outer shell with a top, a bottom, and sides. The mounting lug also includes a bore through the outer shell from the top to the bottom. The mounting lug also includes a cavity, an interior lattice, and a damping media. The outer shell and the bore enclose the cavity. The interior lattice is within the cavity and stiffens the mounting lug. The damping media is enclosed in the cavity and between solid portions of the interior lattice.

A particle impact damper including an outer body defining an internal cavity and a plurality of spherical particles positioned within the cavity. The spherical particles each include an inner core made of a high density and a high modulus material, such as tungsten, and a thin outer coating made of a high coefficient of friction and low yield strength material, such as aluminum. The cavity has a high coefficient of friction inner surface. The spherical particles can be provided in two sets of particles including a first set having a larger diameter and a second set having a smaller diameter so as to increase the fill ratio of the particles in the cavity.

A vehicle vibration damper assembly may include a bracket, a canister, and steel shot. The bracket is for mounting to an engine compartment rail in mechanical contact with an engine. The canister is mounted to the bracket and defines a cavity. The steel shot is disposed within the canister in an amount selected to reduce an amplitude of a vibration of the engine during operation. The bracket may be mounted to an engine compartment rail. The bracket may be secured proximate an engine compartment rail such that the canister is mechanically connected to the engine. The amount of the steel shot may be such that energy generated by the engine during operation is dissipated into heat energy or impact energy by the steel shot.

An apparatus which damps oscillation in a ski, the apparatus comprising an enclosure, a cavity encompassed by the enclosure, and an aggregate located in the cavity. The cavity has a dimension in a direction perpendicular to a gliding surface of the ski which is larger than a thickness of the ski in a location adjacent to the enclosure. The aggregate, in its tapped density, occupies substantially less volume than a volume of the cavity, thereby allowing significant travel of the aggregate in the cavity. Oscillation accelerates and decelerates the enclosure, resulting in accelerations and decelerations of the aggregate which cause it to acquire and lose kinetic energy. The aggregate's acquisition and loss of kinetic energy attenuates the oscillation.
