摘要

针对冲击波防护对轻质高吸能结构的迫切需求，研究了不同相对密度热塑性聚氨酯弹性体(ThermoplasticPolyurethane

TPU)桁架点阵结构对不同强度冲击波的衰减特性，提出点阵结构变密度设计方法，以增强宽冲击波范围内的防护性能。以Fluorite结构为元胞设计5种相对密度(10%、15%、20%、25%、30%)TPU材质的均质桁架点阵结构，并对其开展了准静态压缩测试和模拟冲击波防护性能评估，选取性能优异的2种结构组合设计了3种变密度结构并重复试验进行验证。试验结果表明：通过改变相对密度可以调节桁架点阵结构弹性模量、平台应力等力学性能参数；在135kPa的冲击波载荷下，10%相对密度均质结构防护效果最好，超压峰值为219.9kPa；在200kPa和280kPa的冲击波载荷下，15%相对密度均质结构防护效果最好，超压峰值分别为340.7kPa和511.8 kPa；通过10%与15%相对密度均质结构结合的变密度结构在3种冲击波载荷下的防护效果进一步提升。

Abstract

In response to the growing demand for lightweight and highly energy-absorbing structures in shock wave protection applications

this study investigates the shock wave attenuation characteristics of thermoplastic polyurethane (TPU) truss lattice structures with varying relative densities under different shock wave intensities. A variable density design approach is proposed to improve protective performance across a broad range of shock loading conditions. Five uniform TPU truss lattice structures

featuring relative densities of 10%

15%

20%

25%

and 30%

were designed using the fluorite unit cell configuration. These structures were subjected to quasi-static compression tests and evaluated for shock wave mitigation performance. Based on their superior mechanical behavior

two configurations were selected for integration into three functionally graded (variable density) designs

which were subsequently validated through repeated experimental testing. Results indicate that key mechanical properties—such as elastic modulus and plateau stress—can be effectively tailored by adjusting the relative density. Under a 135 kPa incident shock wave load

the 10% relative density homogeneous structure demonstrated optimal protection

yielding a peak overpressure of 219.9 kPa. For higher-intensity shock waves at 200 kPa and 280 kPa

the 15% relative density homogeneous structure performed best

with measured peak overpressures of 340.7 kPa and 511.8 kPa

respectively. Notably

the hybrid variable-density structures combining 10% and 15% relative density regions exhibited enhanced protective performance across all tested shock wave intensities.
