吸能缓冲防护服装的研究进展

为优化低速冲击条件下吸能缓冲服装的功能防护性、穿着舒适性,叙述了国内外吸能缓冲服装可触发式防护、非可触发式防护2种防护方式的研究现状,详细阐述了研发过程中该类服装非着装和着装状态下防护性能测试的3种方式及相关标准,并分析了各种方法的优缺点。研究表明:吸能缓冲服装的可触发、非可触发防护涉及到电子电工、医学、服装等多领域交叉合作,就缓冲材料本身,在满足基本防护性能的同时应注重其服用性能;防护性能测试方面,认为数值模拟可规避较多不可控风险,并提出模拟模型应充分考虑“人-服装”结合,且测试标准应向着统一化、规范化发展。

Research progress in impact-energy-absorbing cushioning garments

In order to establish understanding for the protection, wear comfort of impact-energy-absorbing cushioning garments under low-speed impact, this paper reports on the research outcomes of two types of protection methods, i.e. triggered protection and non-triggered protection, used for impact-energy-absorbing cushioning garments both in China and abroad. It reviews the three test methods and related standards of the protective performance test of the garments in the non-dressing and dressing states, and then discusses the advantages and disadvantages of these methods. The results show that the triggered and non-triggered protection of impact-energy-absorbing cushioning garments involves multidisciplinary collaborations of many fields such as electrics, medicine, clothing, and so on. As for the cushioning materials, they should meet the wearability requirement while satisfying the basic protective performance. In terms of protection performance evaluation, numerical simulation is shown to be able to avoid uncontrollable risks, and simulation models should fully consider the "human-clothing" interaction. The review concludes that test standards should be developed for unification and universality.
