Design and Implementation of a Damage Assessment Toolkit for Blast-fragmentation Warhead and Its Typical Applications

In order to address the problem of low computational real-time performance in the damage assessment of armored vehicle targets struck by high explosive munitions, a parametric target structural model is constructed. The structural model can be used to significantly improve the efficiency of intersection computations in conjunction with a stage-wise shotline intersection calculation algorithm. An evaluation toolkit (ETK) is designed and implemented, providing interfaces for geometric structure modeling, damage level and damage tree modeling, damage criteria modeling, high explosive munition lethality field modeling, and shotline intersection calculation. A high explosive munition damage assessment system with hierarchical and modular architecture for typical armored vehicle targets is developed by parametrically defining the structural elements and their combinations based on ETK. Case studies verify that the damage assessment system is capable of completing a single damage assessment calculation within seconds, providing effective support for the protection design of armored vehicles and the formulation of firepower strike plans. The proposed architectural design approach may offer valuable reference for the implementation of similar systems.
