冲击载荷下周期性层状管结构中应力波衰减特性研究
|
摘要
利用分离式霍普金森压杆试验装置(SHPB)开展了周期性层状管结构的动态冲击试验,结合有限元数值仿真研究了冲击载荷作用下周期性层状管结构中瞬态应力波传播与衰减特性。基于固体晶格能带理论,研究了周期性层状管结构的带隙特性,阐明了能带结构与应力波频谱衰减区域的对应关系,分析了层状管的材料和结构参数对带隙的影响。研究结果表明,周期性层状管结构具有良好的冲击应力波衰减特性和抗冲击性能,其应力波衰减特性主要由其带隙引起,层状管的材料和结构参数对带隙的频率范围和宽度具有有效的调节作用。该研究工作可以为工程抗爆抗冲击提供新思路。
Here, dynamic behavior, stress wave propagation and attenuation characteristics of periodic layered tubes under impact loadings were investigated with the split Hopkinson pressure bar(SHPB) device combining with the finite element numerical simulation. Based on the solid lattice energy band theory, periodic layered tube structures' band gap characteristics were studied to clarify the relation between energy band structure and stress wave frequency spectrum's attenuation region and analyze the effects of layered tubes' material and structural parameters on band gap. Results showed that the periodic layered tube structures possess good impact stress wave attenuation characteristics and anti-impact performance; their impact stress wave attenuation characteristics are mainly caused by their band gap ones; layered tubes' material and structural parameters can effectively regulate the frequency range and width of band gap. The study results provided a new idea for anti-blast and anti-impact engineering.
