摘要：
In order to systematically explore the properties of the mesh bumper under hypervelocity impact, the quantitative research of protect characteristics was carried out with the numerical simulation. The experiments, in which the projectile impacted the multi-layers mesh bumper at hypervelocity, were simulated using the Ls-Dyna hydro-codes. The results for simulations and experiments were compared and analyzed. The effectiveness and accuracy of the simulation model is proved. It is shown that the morphologies of debris cloud were obviously varied with the change of impact position.
