摘要:

针对模拟和再现爆炸冲击试验的三维场景可视化需求,基于虚拟仿真技术,结合爆炸场相关计算模型,搭建了一个用于研究和预测爆炸冲击波对目标的毁伤过程及毁伤效应的虚拟仿真系统。系统采用分层架构,涵盖场景管理、交互设计、威力表征与可视化仿真等层级,支持爆炸参数灵活配置、目标模型动态加载及多视角交互分析,能够适应不同类型和规模的爆炸场景。此外,基于Niagara粒子系统与物理引擎实时渲染技术,系统精准表征了火焰、烟雾、冲击波传播及目标毁伤效果如混凝土破碎、车辆结构变形等,并通过动态烟雾浓度调节功能优化观测清晰度。仿真系统以高度逼真的图形界面观察爆炸冲击的动态过程及物理现象,并支持用户在三维场景中的多视角及可缩放观察,从而提升研究的直观性和理解深度,大幅减少了实际试验的时间和成本,提供了一种安全、可靠且经济的研究手段。

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.
