利用Abaqus中不同的超弹性本构模型对橡胶材料试验数据进行拟合，在此基础上选择合适的本构模型，然后分析手性蜂窝覆盖层的水下非接触性爆炸动响应特点，并研究主要设计参数包括高度、镂空率和面板材料对抗冲击性能的影响。研究结果表明，随着高度、镂空率和面板材料波阻抗的增加，覆盖层的抗冲击性能和缓冲性能得到提高。对该覆盖层的水下爆炸抗冲击防护机理、性能的认识和结构形式的进一步优化设计提供参考。

Test data of rubber material were fitted with hyperelastic constitutive models in ABAQUS finite-strain package.On the basis of the fitting results,a proper model was proposed.Furthermore,dynamic responses of chiral honeycomb rubber claddings subjected to UNDEX were investigated,and the influences of main design parameters including height,porosity and panel material on shock resistance were discussed.It is found that as cladding's height, porosity and panel wave impedance increase,its shock resistance and buffering effect will be improved.The conclusions play an instructive role in understanding the protective mechanism and the performance of chiral honeycomb claddings subjected to underwater explosion,and also provide a guideline to further optimal design.
