剪切增稠液/硅橡胶复合材料抗冲击性能数值研究OA

The composite material composed of shear thickening fluid and silicone rubber is a new kind of impact resis-tant material.The finite element model of the composite was established,and the impact process was numerically simulated using fluid-structure coupling algorithm in the LS-DYNA program.After verifying the accuracy of the model,the influences of impact velocity,droplet distribution and energy-absorbing liquid material on the energy absorption characteristics of the composite material were studied.The results show that the energy absorption efficiency of the composite material can reach more than 30%,and changing the droplet distribution form and liquid material can greatly improve the energy absorption ef-ficiency of the composite material.
