    Abstract:

    Stacked micro data acquisition systems are widely used in aerospace test analysis, automotive safety testing, biomechanics research, automotive black boxes, etc. These applications require high impact resistance and light weight. In this paper, a new type of stacked high-impact resistant structure is designed in response to this requirement. First, through finite element modeling, a comparative analysis of the high-impact structure under the new composite material of aluminum alloy, gun steel, and carbon fiber was carried out. Second, the impact resistance of the structure composed of the new carbon fiber composite material under different wall thicknesses was simulated. Finally, the impact test proves that its impact resistance is not less than 4000G. The experimental results show that the structure has the advantages of light weight, random increase or decrease of stacking quantity, and easy installation.
