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.

Implementations provide cold spray additive manufacturing (“CSAM”)-based fabrication of a complex multi curvature part (“CMCP”) by cold spraying onto a mold. Implementations achieve the desired shape and dimensions of a CMCP having variable surface thicknesses and utilize reinforcements integrated during CSAM. Reinforcements are integral to each CMCP as soon as fabrication is complete, and maintain stiffness, avoid fluttering, and provide other similar benefits. Implementations provide a stiff CMCP with multiple curvatures having fully controllable variable thicknesses. Integral reinforcements added during fabrication avoid tolerance issues by avoiding coupling non-reinforced CMCPs to reinforcements or other post-fabrication adjustments. CSAM-based CMCPs, having directly integrated reinforcements, exhibit superior tolerances that do not need to be re-worked or otherwise corrected after fabrication. Reinforcement attachment methods that have complex load transfer behavior are not necessary. In some implementations, simplifying load transfer increases the maximum load and decreases the overall weight of the finished CMCP.
