[0052] S14. Establishing a damage tree and damage equivalent data: Establishing a damage tree according to the damage logic of each QT component, determining the damage mode at different damage levels and the damage criteria and equivalent data of each component;

[0053] S2.

[0056] S23, determine the standard geometry of each component that can represent the actual size and shape characteristics of the QT target as the basis for constructing an equivalent three-dimensional model;

[0057] After the standard geometric bodies of each component are determined in S3 and S2, the reference point position, coordinate system direction and basic size parameters of each geometric body are defined;

[0058] S31, determining the reference point position and coordinate axis direction for each standard geometric body, and defining a unified coordinate system to describe the geometric relationship of the components;

The geometric structure information is expressed in the form of a parameterized equivalent three-dimensional structure model, including the equivalent geometric size, position and attitude parameters of the components; the damage related information includes target structure tree data, damage level data, damage tree data, component material property data, damage criterion data, etc.

[0072] Suppose you want to build a vulnerability model for a certain type of QT, the steps are as follows:

[0073] Step 1: Analyze the structure and function of QT: Through the design drawings of QT, analyze the functions of various components such as hull, weapon system, propulsion system, etc., and establish a structure tree.

[0074] Step 2: Classify the damage level: Determine the damage level of each component based on its importance. For example, the propulsion system is a first-level component (important) and the hull is a second-level component (secondary).

[0075] Step 3: Simplify the geometry and design a parametric model: For complex system components (such as propulsion devices), use cylinders or rectangles to simplify the geometry, and determine the size, position, etc. through parametric design. The standard geometry suitable for describing QT components is shown in Table 1:
