A buffer energy-absorbing structure with multiple energy-absorbing effects with microfiltration membrane

Abstract

The invention discloses a buffer energy absorbing structure with a micro-filtration membrane and multiple energy absorbing effects. The structure comprises a first shell, a second shell and a middle separation layer produced by high-elasticity macromolecular materials, and a substrate produced by metal; the first shell and the second shell respectively coat the upper and lower surfaces of the substrate; a cavity defined by the first shell and the substrate is divided into a first cavity and a second cavity by the middle separation layer; a third cavity is defined by the second shell and the substrate; the second cavity and the third cavity are filled with gas; the first cavity is filled with solid particles; the micro-filtration membrane is mounted at the middle part of the substrate, and enables the second cavity to communicates with the third cavity to form the buffer energy absorbing structure with the micro-filtration membrane and multiple energy absorbing effects; and the buffer energy absorbing structure achieves multiple energy absorbing effects to deal with different impact environments, is excellent in durability and safety, and is simple in production, low in cost and suitable for large-scale industrial production.

Description

Technical field [0001] The invention relates to an energy absorption structure, in particular to a buffer energy absorption structure with multiple energy absorption effects with a microfiltration membrane. Background technique [0002] Vibration and shock are one of the common harmful phenomena in industrial production. These vibrations and shocks not only affect the accuracy of the mechanical equipment, but also seriously damage the mechanical equipment. In order to reduce the impact of vibration and shock on mechanical equipment, it is necessary to arrange various energy absorption and vibration damping devices or structures on the mechanical equipment. [0003] The basic principle of energy absorption is to convert impact energy into other energy, such as thermal energy, elastic deformation energy, and electrical energy. Damping pads, springs, leaf springs and disc springs are common energy-absorbing devices or structures in industrial production. These devices convert impact...

Problems solved by technology

After multiple impacts, the honeycomb sandwich structure will be damaged and ineffective, and the severe impact will cause industrial equipment to be severely impacted and cause production accidents, causing huge losses to the country and the people

[0005] A single energy-absorbing method cannot meet the needs of actual industrial production. In order to improve the adaptability of the energy-absorbing structure, a new energy-absorbing structure with multiple energy-absorbing effects must be developed.
