Composite negative-poisson-ratio honeycomb vibration isolation and impact resistance device

Abstract

The invention provides a composite negative-poisson-ratio honeycomb vibration isolation and impact resistance device which comprises a composite panel (1), a negative-poisson-ratio honeycomb core (2), an outer sealing plate (3), an inner sealing plate (4) and a bottom sealing plate (5), and the overall device is formed in a welding manner. The bottom sealing plate of the device is connected with the floor through a bolt, and mechanical equipment is placed on the composite panel to be connected through a bolt. According to the composite negative-poisson-ratio honeycomb vibration isolation and impact resistance device, adjustable parameters are wide and include the composite laying manner, the inner and outer sealing plate thickness, the negative-poisson-ratio honeycomb core layer number and angle and the like; the impact resistance performance and low-frequency vibration isolation performance are both taken into consideration; the defects that a traditional equipment base is heavy and low in effect are overcome; and a new field is exploited for engineering application of the negative-poisson-ratio honeycomb structure.

Description

technical field [0001] The invention relates to a vibration isolation and shock resistance device, in particular to a composite material negative Poisson's ratio honeycomb vibration isolation and shock resistance device. Background technique [0002] The development of high-efficiency light-weight vibration isolation and shock-resistant devices is a frontier topic in the design and research of mechanical equipment noise and vibration comfort. Traditional vibration isolation and shock resistance devices mainly include single-layer vibration isolation system, double-layer vibration isolation system and floating raft vibration isolation system. Because the single-layer vibration isolation system is simple and effective, it is widely used in engineering, but it has obvious disadvantages: (1) When the disturbance frequency of the machine is low, the stiffness of the vibration isolator must be designed to be very small, and the system stability is poor; (2) ) The combined result ...
