In order to reduce casualties caused by improperly driven vehicles in maintenance construction zones

this paper proposes an aluminum honeycomb attenuator installed at the rear of road maintenance vehicles. Currently

there is limited research on this type of attenuator. To address this

the paper establishes a high-precision finite element model for the attenuator and utilizes numerical simulation methods to study its collision protection performance from three aspects: energy absorption

directional controllability

and blocking capability. The research results indicate that the aluminum honeycomb attenuator can effectively reduce the impact force and acceleration experienced by occupants during collisions. Additionally

the appropriate strength of the aluminum honeycomb is crucial for enhancing collision protection performance.
