doi:10.12382/bgxb.2025.0336

Abstract

Abstract:

For the three-dimensional scene visualization of simulating and reproducing the explosive shock experiments, a virtual simulation system,which is designed for studying and predicting the damage process and effects of explosive shockwaves on targets, is built based on virtual simulation technology and the related explosive field calculation models. The system adopts a layered architecture, covering the scene management, interaction design, power calculation and visualization simulation, and supporting the flexible configuration of explosion parameters, dynamic loading of target models and multi-perspective interaction analysis, which can adapt to different types and scales of explosion scenes. Furthermore, based on Niagara particle system and physics engine real-time rendering technology, the system accurately characterizes the flame, smoke, shockwave propagation and target damage effects, such as concrete crushing, vehicle structure deformation, etc., and optimizes the observation clarity through the dynamic smoke concentration adjustment function. The simulation system provides a highly realistic graphical interface to observe the dynamic processes and physical phenomena of explosive shocks, and supports the multi-perspective and scalable observation in 3D scene. This enhances the intuitiveness and depth of understanding in research, significantly reducing the time and cost of actual experiments, and offering a safe, reliable and cost-effective research method.
