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.
