Vibration absorbers with different natural frequencies for a device
A recently granted patent (Publication Number: US11885391B2) discloses a device comprising a body with vibration absorbers capable of oscillating between two positions, each absorber having a unique natural frequency. The absorbers include deformation parts with faces designed to exert shear forces during oscillation. The deformation parts consist of stacked strips that deform by bending, causing movement along the stacking direction. Additional layers like resin or elastomer may be included, along with ribs for reinforcement and weight suspension for movement relative to the body.
Furthermore, the patent describes a vehicle, particularly an aircraft, equipped with the aforementioned device. The vehicle includes a platform where the body oscillates between positions, with different natural frequencies for various vibration absorbers. The body consists of a beam and a head, with absorbers mounted on the beam's end. This innovative technology aims to enhance vibration absorption in vehicles, particularly aircraft, by utilizing unique deformation mechanisms and natural frequencies to optimize performance and stability during operation.
