Self-recovery multi-direction stretching type energy absorption superstructure

Abstract

The invention relates to a self-recovery multi-direction stretching type energy absorption superstructure. The self-recovery multi-direction stretching type energy absorption superstructure comprises a plurality of energy absorption superstructure single bodies, each energy absorption superstructure single body comprises a support and a cosine structure, each support comprises four connecting columns of the same structure, one ends of the four connecting columns are connected with the same point, and the included angles between any two adjacent connecting columns are the same; the other ends of any two adjacent connecting columns are respectively connected with one cosine structure; and external connecting structures are arranged on the sides, away from the supports, of the cosine structures, every two adjacent energy absorption superstructure single bodies are connected through the corresponding external connecting structure, and all the cosine structures on each energy absorption superstructure single body are connected with the cosine structures on the adjacent energy absorption superstructure single body through the corresponding external connecting structure. According to the self-recovery multi-direction stretching type energy absorption superstructure, energy of impact vibration can be greatly absorbed through the stretching phase change process, and the impact vibration reduction requirement of a target object is met.

Description

Technical field [0001] The present invention relates to the field of vibration control, in particular a self-recovery multi-directional tensile suction super structure. Background technique [0002] The impact exists in nature and human life, such as earthquakes, gunfire emission. The process usually has a short time, but contains huge energy and force. In the case of no protection, it is very large to cause damage to the equipment, affecting the health of people. The traditional method is to use the quality-damping-spring structure such passative system or active control system to absorb impact energy, relatively mature technology. At the beginning of the 21st century, with the concept of "super structure" first proposed in the optical field, scientific research workers in various fields put their eyes into the "super structure" research work, which included research work in the field of vibration control. By. Using the special structure of manual design, the overall material ex...
