Description

Technical Field

[0001] The utility model relates to the technical field of buffer rings, in particular to an adjustable energy absorber buffer ring. Background Art

[0002] The new generation of aerospace design missions has an increasingly urgent need for multifunctional structures with lightweight characteristics. Some new application scenarios have also put forward new requirements for multifunctional structures. Manned deep space exploration operations require deployable and scalable multifunctional structures as temporary buffer energy absorption devices and equipment vibration reduction platforms; space station docking, spacecraft landing in outer space and other scenarios not only require lightweight structures as energy absorption and vibration reduction devices, but also hope that these structures have the ability to be reusable (no irreversible damage will occur after impact and can be used again) or recyclable (that is, some components can be recycled and reused after failure) to reduce transportation costs. However, there are still certain problems when using the existing energy absorber buffer ring:

[0003] For example, an energy absorbing element and its energy absorbing buffer with publication number CN116771838A, the technical scheme of which is as follows: the energy absorbing element comprises at least two structural units in the form of truncated cone shells; the structural units are sequentially stacked in the direction of their own axis to form a stacked sleeve structure, and the side walls of adjacent structural units have an annular overlapping interface; when an external load is applied to the energy absorbing element, the structural unit can have annular elastic strain under the interaction force of the annular overlapping interface between adjacent structural units, so that there can be interface slip between adjacent structural units. The energy absorbing element of the present invention can not only inherit the advantages of discrete structures (the structure can be disassembled and assembled, and a single element can be replaced after failure), but also have the characteristics of a "circumferential stress-dominated" structure, that is, it has high bearing capacity. At the same time, the structure has a good energy dissipation capacity, thereby having a good buffering and vibration reduction performance, and the existence of the annular overlapping interface has a good hindering effect on the expansion of cracks, but the annular object that plays a buffering role in the existing energy absorber cannot adjust its circumference size, and the buffering of energy cannot be adjusted in a targeted manner.

[0004] In view of this, we conducted in-depth research on the above issues, which led to the present case.

[0005] In view of the above problems, an innovative design is carried out based on the original energy absorber buffer ring. Utility Model Content
