摘要
为了进行橡胶材料手性蜂窝覆盖层的水下非接触性爆炸动响应、抗冲击性能及机理研究;利用Abaqus中的不同超弹性本构模型对材料试验数据进行拟合,在此基础上选择合适的本构模型,然后分析其响应特点,研究主要设计参数包括高度和镂空率对抗冲击性能的影响。研究结果对该覆盖层的水下爆炸抗冲击防护机理和性能认识有一定指导作用,为结构的进一步优化设计提供参考。
As a valuable composite structure,the dynamic response,shock resistance and the mechanism of chiral honeycomb rubber claddings subjected to UNDEX was studied.Rubber test data were fitted using the hyper-elastic models in ABAQUS finite-strain package.On this basis,a suitable constitutive model was chosen.Then,the dynamic characteristics of the structure and the influence of main design parameters,including height and porosity of the structure,on shock resistance were analyzed and discussed.The results have provided a clew for understanding the shock-resistance mechanism of the claddings subjected to underwater explosion,and a guideline for further optimal design of this structure.
