| 目的 在高冲击、 高过载的环境下， 研究高过载测试电子记录器的环阻尼缓冲防护结构的缓冲防护性能。方法 从结构和材料上对高过载测试电子记录器中的环阻尼缓冲防护结构进行改进， 采用具有梯形齿环状缓冲防护结构， 在钢壳内侧壁和内胆盖外侧壁、 内胆外侧壁之间装有泡沫铝-聚氨酯或泡沫铜-聚氨酯等复合材料， 以更好地起到缓冲防护作用。接着对复合材料结构试样进行Ansys仿真实验， 研究泡沫铝-聚氨酯复合材料结构的抗高过载、 高冲击性能。结果 灌封质量分数为25%的聚氨酯时的泡沫铝-聚氨酯复合材料结构的抗高过载性能较好， 灌封质量分数为4.9%聚氨酯时的泡沫铝-聚氨酯复合材料结构的抗冲击性能最好。结论 梯形齿环状结构较三角齿螺纹结构有更好的稳定性。 |

| The aim of this work was to study the cushioning performance of the damping ring cushioning protective structure of the high overload test electronic recorder in the environment with high impact and high overload. The damping ring cushioning protective structure of the high overload test electronic recorder was improved both in the structure and the material. A trapezoidal toothed ring cushioning protective structure was used, and composite materials such as aluminum foam-polyurethane or copper foam-polyurethane were filled between the steel shell inner wall, the tank cover outer wall and the tank outer wall for better cushioning. Then, Ansys simulation experiment was conducted for the composite material structure specimen, to study the high overload and high impact resistance of the aluminum foam-polyurethane composite material structure. The results showed that filling of aluminum foam-polyurethane with a polyurethane content of 25% granted the composite material structure with relatively high resistance against high overload, while filling of aluminum foam-polyurethane with a polyurethane content of 4.9% resulted in the composite material structure with the best impact resistance. In conclusion, trapezoidal toothed ring structure had higher stability than the triangle thread structure. |
