A Precise Damage Assessment Method for Lethal Blast Warheads Against Quadruped Robots

doi:10.16182/j.issn1004731x.joss.25-0056

Abstract

Abstract:

To accurately evaluate the damage efficiency of a lethal blast warhead on quadruped robots, a typical quadruped robot replication model and vulnerability damage tree were constructed through Autodesk Inventor. The power field calculation model of a lethal blast warhead was introduced. Based on the high-precision collision detection and graphic rendering technology of UE, this paper carried out the intersection detection of destructive elements and targets and realistic scene visualization. A visualization system for damage assessment of quadruped robots by a lethal blast warhead was developed, featuring capabilities such as parametric modeling of the lethal blast warhead, power field evolution of fragment shock waves, intersection detection of destructive elements and targets, component-level physical penetration depth characterization, damage probability calculation, and rendering visualization of the damage process and effect. The system significantly improved assessment precision in areas such as precise physical model reproduction, the curved trajectory of a fragment with gravity, and intersection detection for multi-component stacking.It can provide support for the protection design of quadruped robots and the formulation of battlefield strike plans, and its development ideas can provide references for the design, research, and development of similar software.
