摘　　要：选用冲击防护常用的经编间隔织物作为试验材料,研究材料粘弹性与其隔冲性能的关系。搭建了阻尼测试平台以测定不同规格的经编间隔织物阻尼比、压缩弹性模量和不同冲击速度下的冲击剩余载荷。试验结果表明,经编间隔织物的粘性或弹性作为单项指标与隔冲性能不存在明确的关系,提出粘弹比可以表征材料粘弹性与隔冲性能关系,在一定实验范围内,合适的粘弹比可获得较好的隔冲性能。Warp-knitted spacer fabric which is commonly used in impact protection is selected as test materials to study the relationship between viscoelasticity and the performance of shock isolation.A damping test platform is built to test different specifications of warp-knitted spacer fabric including compression elastic modulus,damping ratio and the residual impact load under different impact speed.Experimental results show that there is no clear correlation between the shock isolation performance and the viscidity or the elasticity.Accordingly,viscosity-to-elasticity ratio is proposed to characterize the relationship between viscoelasticity and shock isolation performance,and it is found that appropriate viscosity-to-elasticity ratio within a certain range can help to achieve better shock isolation performance.
