谐振骨料特性对超材料混凝土防爆减振性能的影响
Effects of Resonant Aggregate Characteristics on Blast Mitigation and Vibration Suppression Performance of Metaconcrete
摘要
Abstract
To investigate the vibration suppression performance of metaconcrete under blast loading,a three-dimensional finite element model of metaconcrete measuring 100 cm×100 cm×30 cm was established based on the theory of locally resonant metamaterials.The Arbitrary Lagrangian-Eulerian(ALE)method was employed to simulate TNT blast loading,and the effects of material properties,geometric dimensions,and non-uniform distribution of resonant aggregates on the vibration suppression performance of metaconcrete were systematically analyzed.The results show that metaconcrete can effectively attenuate blast-induced stress waves through local resonance.Within the parameter ranges studied,the elastic modulus of the coating has the most significant influence on the peak vibration velocity,while none of the parameters show a statistically significant effect on the peak stress.The bottom-enriched distribution of resonant aggregates does not degrade the overall vibration suppression performance;instead,a periodic arrangement exhibits superior overall performance due to the combined effects of local resonance and Bragg scattering.A four-layer resonant aggregate structure with optimized parameters achieves 93.5%attenuation rate of impact energy.This study provides theoretical references for material selection,parameter design,and process control in metaconcrete.关键词
