A Damping Alloy and Lattice Composite Reinforced Vibration Suppressing Structure

Abstract

A damping alloy and lattice composite enhanced vibration suppression structure, including a Mn-Cu damping alloy base and a lattice structure arranged in the Mn-Cu damping alloy base; the Mn-Cu damping alloy base has a polyhedral cavity structure, It includes a plurality of installation side walls assembled with other components, and a plurality of support side walls connected to the installation side walls; a through hole is provided on an installation side wall outside the polyhedron, and the optical lens is fixed on the installation platform outside the base. The base installation platform is fixed on the installation side wall where the through hole is set; the imaging system support structure is fixed inside the polyhedron cavity structure of the Mn-Cu damping alloy base, and the optical lens is set on the input optical path of the imaging system through the through hole; Mn-Cu The interior of the supporting side wall on the Cu damping alloy base is arranged in a lattice structure. Avoid strong vibration and shock input from being transmitted to optical lenses and imaging systems, and greatly improve the high-precision stability of the guidance system in extreme service environments.

Description

technical field [0001] The invention relates to a vibration suppression structure, in particular to a vibration suppression structure reinforced by a damping alloy and a lattice compound. Background technique [0002] The new generation of aircraft equipment has extreme service environments such as high speed, high maneuverability, strong vibration and shock, etc.; extreme light weight, the structural weight of the system is reduced from 30% to 10%; extreme high performance accuracy, order of magnitude improvement in detection capabilities and other typical technical characteristics . The detection and guidance system is generally located on the top of the aircraft. It is the core system of the aircraft system and bears the extreme force-heat load brought by the high-speed and high-mobility aircraft. Therefore, extreme lightweight and high-precision stability in extreme service environments are the core problems in the development of guidance systems. The vibration and sho...

Problems solved by technology

The development of the traditional detection and guidance structure uses aluminum alloy materials, which need to add additional structural reinforcement, vibration isolation and other protective measures. The function is single and the structure is heavy. This cannot be achieved under the requirements of the new generation of aircraft equipment with narrow space and strict lightweight indicators.
