doi:10.12382/bgxb.2025.0337

Abstract

Abstract:

To meet the practical requirements of swiftness and accuracy in shaped charge penetration simulation, a real-time tracking and verification software for jet penetration simulation was designed and implemented through further development of an existing simulation program. Developed based on Qt, the software tracks the simulation process and reads key results in real time, such as jet length and tip velocity. A visualized display window was constructed to enable synchronous visual tracking of target physical quantities. The software integrates quasi-steady theoretical models of shaped charge jet penetration, enabling automated verification of simulation results against predefined error thresholds. This capability allows timely detection of numerical anomalies and unphysical phenomena, thereby ensuring the scientific validity and practical accuracy of the computational outcomes. The penetration of thick steel plates by shaped charge jets was analyzed to investigate the process and the influence of cone angle and charge diameter. The results demonstrate that the software is well-suited for data tracking and verification in jet penetration simulations, ensuring the scientific validity and reliability of the computational results while improving operational efficiency. Furthermore, it provides a robust foundation for subsequent data extraction and in-depth analysis.

Key words: shaped charge jet, penetration, simulating calculation, tracking, verification, visualization
