摘　　要：为探究充气面料的充气厚度临界值及其在动态冲击下的缓冲防护性能,对5种不同花型、不同充气厚度的充气面料进行内气压测试和跌倒冲击试验,分析了充气厚度、花型对充气面料动态缓冲特性的影响。结果表明:5种充气面料的充气厚度临界值为20mm、31mm、55mm、30mm、52mm;在临界值范围内,充气厚度越大,防护效果越好,超过临界值,防护效果下降;花型的充气气室形状对面料的缓冲防护有较大影响。本研究从综合性角度评价了充气面料的缓冲减震性能,以期为充气面料在实际应用中的设计提供参考。In order to explore the critical thickness value of the inflatable fabrics and the cushioning and protection performance under dynamic impact,the internal air pressure test and the fall impact test have been carried out on 5 kinds of inflatable fabrics with different patterns and different inflatable thickness,and the effect of inflatable thickness and pattern on the dynamic cushioning characteristics of inflatable fabrics has been analyzed.The results showthat the critical thickness values of the five inflatable fabrics are 20mm,31mm,55mm,30mm,52mm.Within the critical value range,the greater the inflation thickness,the better the protective effect.Beyond the critical value,the protective effect decreases.The shape of the inflatable air chamber pattern has a great impact on the cushioning and protection of the fabrics.This study evaluates the cushioning and shock absorption performance of inflatable fabrics from a comprehensive perspective,hoping to provide reference for the design of inflatable fabrics in practical applications.
