Isolation coupler for structural assembly and method for attenuating load

Abstract

An isolation coupler for coupling a functional element to a support structure includes a first bracket. The first bracket includes a plurality of first bracket sides. The plurality of first bracket sides form a closed polygonal shape in plan view. The isolation coupler also includes a plurality of isolators coupled to each of the first bracket sides. The isolation coupler also includes a second bracket. The second bracket includes a plurality of second bracket sides. The second bracket side is coupled to the isolator. The number of the second bracket sides is equal to the number of the first bracket sides, and the second bracket sides form a closed polygonal shape in plan view. An isolator separates each of the first bracket sides from a corresponding one of the second bracket sides to attenuate a load transmitted from the first bracket to the second bracket.

Description

technical field [0001] The present disclosure relates generally to structural assemblies, and more particularly to an isolating coupler for a structural assembly that couples a functional element to a support structure. Background technique [0002] In various industries, it may be desirable or even necessary to attenuate shock and / or vibration transmitted from a supporting structure to a piece of functional equipment. Shock loads are typically high magnitude, short duration forces. Shock loads can have vibrational frequencies ranging from a few Hertz to several kilohertz or more, can be instantaneous or continuous in nature, and can have axial and / or transverse components. For example, in the aerospace industry, there is a need to prevent the substantial mechanical vibrations and / or mechanical shocks generated during the operation of aerospace vehicles (e.g., aircraft, spacecraft, satellites, rockets, etc.) functional equipment. Mechanical vibration and / or mechanical sho...

AI Technical Summary

Problems solved by technology

Mechanical vibration and / or mechanical shock may damage or cause a functional device to malfunction if sufficient shock loads are transmitted to the functional device

Additionally, in the aerospace industry, vehicle space and weight constraints and the need for a high degree of design flexibility with respect to strength and load attenuation requirements can limit the use of existing shock attenuation methods
