Abstract:
A damping shock absorber includes a pipe and a plurality of shock absorbers configured on the pipe. The shock absorber includes a main body sleeved on the outer periphery of the pipe and a damping medium filled in the main body. The main body is provided with an inner cavity, and the inner cavity is divided into a plurality of chambers for placing the damping medium separately. A method for designing the damping shock absorber, wherein the main body is filled with the damping medium, such that the shock of the pipe or a shaft body is reduced, ensuring the smooth operation of the pipe or the shaft body, and further ensuring the safety and efficiency of the pipe or the shaft body in a working process. The damage to the pipe or the shaft body and the shock interference to other linked apparatuses are greatly avoided.
Abstract:
According to certain embodiments, a container assembly for protecting a flexible panel comprises a back panel positioned behind the flexible panel and offset by a first substantially airtight compartment, a front panel positioned in front of the flexible panel and offset by a second substantially airtight compartment, and a stiffener panel positioned in front of the front panel and offset by a third substantially airtight compartment. The front, back, and stiffener panels each comprise one or more rigid materials. Each rigid material has higher natural frequency and lower excursion properties than the flexible panel. The container assembly is tuned using fixed, gas-piston principles to impart the higher natural frequency and lower excursion properties of the rigid materials to the flexible panel such that the natural frequency of the flexible panel increases and the extent to which the flexible panel experiences excursions greater than 350 microns is reduced.
Abstract:
A bumper pad device is provided that comprises an elongated body portion, a pair of flaps, and fasteners for securing the flaps to one or more wall surfaces. The flaps include an interior surface supporting a first fastener, whereby a separate, elongated surface is first affixed to a wall surface and used to support a complimentary second fastener that secures the flap thereto. The flaps are connected to the body portion in a pivotable relation such that the flaps can secure around exposed edges of walls or around the corners of interior entryways. The pad body portion supports a filler material therein to attenuate impacts, and is ideally suited to protect young children from injury upon impact with walls, corners, and door frames. The exterior surface of the bumper pad device may include ornamental adornments and indicia suitable for use with children.
Abstract:
A new and novel impact energy attenuation material, impact energy attenuation module employing the material and a fit system for optimizing the performance thereof is provided. Non-linear energy attenuating material consisting of a plurality of loose particles is employed for impact energy dissipation. The loose particles are preferably spherical elastomeric balls. An impact energy attenuation module includes a container that holds the loose particles. The impact energy attenuation module can be provided in a wide range of sizes and shapes and the loose particles can be provided in different materials, sizes, density, compaction and hardness to suit with the application at hand. A matrix of impact energy attenuation module are provided about the surface of a shell to provide the required impact energy attenuation. The material, impact energy attenuation module and system of the present invention are well suited for protection of body parts and other cushioning and protection needs.
Abstract:
A component defines at least one chamber that is confined by the component. The chamber has an inner surface. A filler material is disposed inside the chamber. Relative movement between the inner surface and the filler material helps dampen vibrations and other oscillations if and when the component is vibrated.
Abstract:
The inventive viscous damping tube stabilizer includes modules or capsules containing a viscous material. Adjacent capsules are linked end to end by a flexible cable, allowing the device o pass through curves such as the U-bend regions of steam generator tubes. The weight of the entire assembly will keep it essentially connected to the tube inner diameter such that any tube vibration is transmitted to the stabilizer. The viscous material may only partially fill the capsules such that even under small motion the material can slip and slide past each other, and/or bump into walls, each microscopically absorbing some of the tube energy. By creating multiple cells inside the capsule, the capsule then have good operating characteristics no matter to what angle the individual capsule is oriented as it rests on the full U-bend. The viscous material may completely fill the capsules, which also have a perforated member positioned therein. Relative movement of the capsule and disc causes the viscous material to pass through the perforations, providing damping resistance to the movement.
Abstract:
An apparatus and method for damping vibrations within a physical object that is subject to vibration, such as for example, a railroad car running board. In one version, an enclosure is substantially filled with a granulated visco-elastic material, such as for example, granulated rubber, that is fixedly attached to the physical object.
Abstract:
A wing-to-body fairing for reducing noise due to wing-to-body fairing vibrations in an aircraft, spacecraft, or vehicle may include a honeycomb center having a cavity which is at least partially filled with particle material.
Abstract:
Oscillating or vibrating components, especially inside rearview mirrors, are provided in motor vehicles. In order to avoid undesirable vibrations of the inside rearview mirror, the mirror housing (3) is reinforced or complex measures need to be taken to secure the mirror housing (3) to the vehicle. The aim of the invention is to at least significantly reduce the amount of vibrations for various components of motor vehicles by using granulate particles (9) as vibration suppression elements which are placed in a recess. The granulate particles (9) make it possible to suppress and attenuate vibrations in a simple manner. The vibration suppressors are advantageously used in inside rearview mirrors in motor vehicles.
Abstract:
Disclosed is a subassembly comprising a braking system which generates friction-induced vibrations. At least one component of the subassembly is exposed to the friction-induced vibrations. Said component can be embodied as a brake pad (9) which is provided with a support plate (5) and a friction lining (10). The support plate (5) and the friction lining (10) form two hollow spaces which are filled with fillings (2) made of energy-absorbing material and are covered by a damping metal sheet (7). The fillings (2) dissipate vibration energy when the brake lining vibrates, thereby contributing to preventing disturbing braking noise from being generated.
