摘要

航空航天、国防军事、交通运输等领域对吸能系统的性能要求越来越高，特别是在应急防护领域，研究吸能系统的自锁特性具有重要意义。本文采用卡扣式薄壁管设计了一种可编辑、易于快速组装、空间全方位自锁的吸能系统，并通过数值模拟验证了该系统在均匀/集中冲击载荷下的空间自锁特性。结果表明，该吸能系统能够承受空间各方向的均匀/集中冲击载荷。通过复合比例评估法(COPRAS)的定量分析和雷达图法的定性分析，验证了3方向(α = 90°，β = 0°)载荷工况的良好综合性能。

Structural design and self-locking performance verification of the snap-fit spatial self-locking energy absorption system under the impact loading

There are increasingly high performance requirements of energy-absorbing systems in aerospace, defense and military, transportation and other fields, especially in the field of emergency protection where the study of self-locking characteristics is of great significance. In this paper, an energy absorption system is designed by snap-fit thin-walled tubes, which can be edited, easy to assemble quickly and spatial omnidirectional self-locking, and the spatial self-locking characteristic of the system was verified by numerical simulation under the uniform/concentrated impact loadings. The results show that the energy-absorbing system can withstand the uniform/concentrated impact loadings in all directions in space. Furthermore, the good comprehensive performance of the loading condition in direction 3 (α = 90 deg, β = 0 deg) was verified by the quantitative analysis of the complex proportional assessment (COPRAS) method and the qualitative analysis of Radar Diagram method.

期刊介绍： International Journal of Crashworthiness is the only journal covering all matters relating to the crashworthiness of road vehicles (including cars, trucks, buses and motorcycles), rail vehicles, air and spacecraft, ships and submarines, and on- and off-shore installations. The Journal provides a unique forum for the publication of original research and applied studies relevant to an audience of academics, designers and practicing engineers. International Journal of Crashworthiness publishes both original research papers (full papers and short communications) and state-of-the-art reviews. International Journal of Crashworthiness welcomes papers that address the quality of response of materials, body structures and energy-absorbing systems that are subjected to sudden dynamic loading, papers focused on new crashworthy structures, new concepts in restraint systems and realistic accident reconstruction.
