Abstract
The honeycomb sandwich structure has attracted much attention with its lightweight advantages in the field of vehicle protection. To understand the anti-explosion performance of honeycomb sandwich panel structure, the effects of geometry, shape and material parameters of different sandwich panel structures were numerically studied, and the anti-explosion performance of the honeycomb sandwich structure was verified by an explosion test. Then, a multi-objective optimization design was carried out basing on the maximum back-plane deformation and the specific energy absorption of the structure mass. The results show that the thickness of the panel, the strength and relative density of the sandwich layer as so as the whole structure height, have significant effects on the anti-explosion performance of the structure. The multi-objective optimization design can well improve the comprehensive anti-explosion performance of the honeycomb sandwich plate structure in the test.
