This invention belongs to the technical field of automotive energy-absorbing structures, specifically relating to a reverse design method for variable-thickness thin-walled energy-absorbing structures. This method allows for the design of thickness variations based on the energy absorption characteristics of the thin-walled energy-absorbing structure itself. For a given impact load condition, the thickness of the automotive thin-walled energy-absorbing structure is used as the design variable, and the total energy absorption value of the thin-walled energy-absorbing structure is used as the design objective. Under the constraint of limiting the total mass of the thin-walled energy-absorbing structure, the aim is to improve crashworthiness. This method starts with reverse design, with the core idea of ​​increasing thickness where needed (where energy absorption is high) and decreasing thickness where it is not needed (where energy absorption is low), aiming for a rational material distribution within the structure. Through this method, engineers can quickly design variable-thickness energy-absorbing structures. This method simplifies the energy-absorbing structure design process, controls costs, and has good operability and convenience.
