Abstract: Honeycomb sandwich structures have been widely used in aeronautics, automotive and marine industry because of their excellent crashworthiness performance, fatigue resistance and energy absorption ability. The honeycomb sandwich structure is susceptible to various speed impacts during service, and these impacts would cause the performance of the honeycomb sandwich structure to decrease or even be damaged. Therefore, it is very important to test and simulate the honeycomb sandwich structure to study the impact resistance and impact process of the honeycomb sandwich structure. This article summarizes the impact test and numerical simulations of honeycomb sandwich structures at home and abroad. In the experimental study, the low-velocity impact and high-velocity impact test scheme are summarized, including Charpy impact test, drop impact test and gas gun test. At the same time, in the simulation research, the modeling of honeycomb sandwich structure, the damage and failure of composite materials, the impact process and the influence of structural parameters on the impact performance are summarized. Finally, a preliminary prospect on the future development direction of the honeycomb sandwich structure impact experiment and simulation is given.
