摘要

摘要: 基于三维非线性LS-DYNA程序，采用动态显式算法对爆炸载荷下V型夹芯板和平板的动态响应进行数值模拟，得出了不同工况下V型板和平板的面板挠度、芯层压缩量及其吸收的能量。结果表明：与平板相比，V型板具有更加优越的防爆性能。当V型板的面板厚度一定时，上面板挠度、芯层的压缩量及其吸收的能量随着V型板夹角的增大而增大；当V型板夹角一定时，上面板挠度、芯层的压缩量及其吸收的能量随着面板厚度的增大而减小。该结果可以为汽车底板防护和其他防爆设计提供参考。

Abstract: In the present work the dynamic response of the V-shaped aluminum foam sandwich panel and that of the flat panel under blast loading were simulated using the dynamic explicit algorithm based on the three-dimensional nonlinear program LS-DYNA. In our simulation the deflection of the panel faces, the core layer compression and the energy absorption of the core layer were examined with special consideration of different working conditions. The advantage of the V-shaped panel has been exhibited when in comparison with the simulation of the flat panel. When the thickness of the face is constant, the deflection of the top face, the core layer compression and the energy absorption of the core layer increase as the included angle of the V-shaped panel increases whereas, when the included angle of the V-shaped panel is constant, the deflection of the top face, the core layer compression and the energy absorption of the core layer decrease as the thickness of the face increases. The simulated results can serve as a reference for the protection design of motors and other devices.
