The invention discloses a rapid modeling method for an armored vehicle target vulnerability model. The method can provide basic data support for armored vehicle vulnerability analysis and damage evaluation. The method specifically comprises the following steps: 1, processing; the method is based on function and structure analysis of an armored vehicle target. Determining an equivalent geometry structure of the target component; rapid establishment of an equivalent three-dimensional structure model of each part of a target is realized in a parameterized equivalent geometry driving mode, and a target structure tree, a damage level damage tree, geometric data of the equivalent model of the parts, material characteristic data and damage criterion data are integrated in a database form to finish modeling of the target vulnerability model of the armored vehicle. According to the armored vehicle target vulnerability model building method provided by the invention, the armored vehicle target vulnerability model can be quickly built, the occupied resources are few, the use cost is low, the efficiency is high, the universality is achieved, and the method has positive significance for armoredvehicle target vulnerability analysis and damage evaluation calculation.
