A high-load-bearing metal-rubber composite vibration isolator with three-way stiffness and damping decoupling

Abstract

The invention discloses a high load-bearing metal-rubber composite vibration isolator with three-way stiffness damping decoupling. Consisting of two identical metal rubber parts, the metal rubber parts are installed between the shell and the base, and independently perform the functions of vibration isolation and buffering in the vertical, horizontal and longitudinal directions respectively, and have corresponding mechanical limit structures. The invention significantly simplifies the design and preparation difficulty of metal rubber parts in the existing three-way vibration isolator through structural layout design, effectively improves vibration isolation and cushioning performance, and has the advantages of simple mechanical structure, convenient installation and disassembly, and wide application range.

Description

technical field [0001] The invention relates to a vibration isolator for airborne electronic equipment, in particular to a high-load metal rubber composite vibration isolator with three-way stiffness damping decoupling, which belongs to the field of mechanical dynamics and vibration. Background technique [0002] The on-board electronic equipment of aerospace vehicles is generally installed in a standard cabinet, which contains sophisticated electronic components or moving and rotating mechanisms, which are easily disturbed by external mechanical vibration sources and impact sources, affecting normal operation. Therefore, airborne electronic equipment needs to be specially designed for adaptability to the mechanical environment. The existing methods mainly adopt two types of measures: the reinforcement design of the electronic equipment structure itself and the vibration isolation buffer system to isolate the equipment from the vibration source ([1] Zhu Lanqin, Yang Wenfang ...
