Damping alloy and dot matrix composite enhanced vibration suppression structure

Abstract

The invention discloses a damping alloy and dot matrix composite enhanced vibration suppression structure. The damping alloy and dot matrix composite enhanced vibration suppression structure comprisesan Mn-Cu damping alloy base and a dot matrix structure arranged in the Mn-Cu damping alloy base; the Mn-Cu damping alloy base is of a polyhedral cavity structure and comprises a plurality of mountingside walls assembled with other components and a plurality of supporting side walls connected with the mounting side walls; a through hole is formed in a mounting side wall on the outer side of the polyhedron, an optical lens is fixed on a mounting platform on the outer side of the base, and the optical base mounting platform is fixed on the mounting side wall provided with the through hole; an imaging system supporting structure is fixedly arranged on the inner side of the polyhedral cavity structure of the Mn-Cu damping alloy base, and the optical lens is arranged on an input light path ofan imaging system through a through hole; and the interiors of the supporting side walls on the Mn-Cu damping alloy base are arranged in a lattice structure. The damping alloy and dot matrix compositeenhanced vibration suppression structure has the beneficial effects that strong vibration and impact input are prevented from being conducted to the optical lens and the imaging system, and the high-precision stability of a guidance system in an extreme service environment is greatly improved.

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.
