摘要

背景:佩戴防护头盔是减少与工作有关的脑外伤的重要预防策略。现有的标准化测试系统用于质量控制,不能对安全帽的性能进行量化测量。目的:分析 I 型工业安全帽的失效特征,并在现有标准化设置的基础上开发一种通用方法来量化 I 型工业安全帽的减震性能。方法:研究选择了具有代表性的基本 I 型建筑安全帽模型。使用两种不同质量(3.6 千克和 5.0 千克)的冲击器,在不同下落高度对安全帽进行顶部冲击试验。结果:当安全帽受到小于临界潜在冲击能量值的冲击时,峰值冲击力与潜在冲击能量之间存在一致的关系。当头盔受到的潜在冲击能量大于临界潜在冲击能量值时,峰值冲击力随着潜在冲击能量的增加而急剧增加。结论:根据潜在冲击能量提出了建筑安全帽安全系数的概念,以量化安全帽的减震性能。所提出的方法将有助于安全帽制造商提高产品质量。

Testing the shock protection performance of Type I construction helmets using impactors of different masses
BACKGROUND:Wearing protective helmets is an important prevention strategy to reduce work-related traumatic brain injuries. The existing standardized testing systems are used for quality control and do not provide a quantitative measure of the helmet performance. OBJECTIVE:To analyze the failure characterizations of Type I industrial helmets and develop a generalized approach to quantify the shock absorption performance of Type I industrial helmets based on the existing standardized setups. METHODS:A representative basic Type I construction helmet model was selected for the study. Top impact tests were performed on the helmets at different drop heights using two different impactor masses (3.6 and 5.0 kg). RESULTS:When the helmets were impacted with potential impact energies smaller than the critical potential impact energy values, there was a consistent relationship between the peak impact force and the potential impact energy. When the helmets were impacted under potential impact energies greater than the critical potential impact energy values, the peak impact forces increased steeply with increasing potential impact energy. CONCLUSION:A concept of safety margin for construction helmets based on potential impact energy was introduced to quantify the helmets’ shock absorption performance. The proposed method will help helmet manufacturers improve their product quality.
