水下射弹超空泡可视化研究

Research on the Supercavitation of the Underwater Projectile Visual Simulation

针对水下高速射弹超空泡模型的特点进行了分析与研究,采用椭圆拟合原理构建了简化的空泡模型,利用OpenGL编程技术完成了实时数据驱动的超空泡模型,并创建了相关三维实体模型,在Vega Prime仿真环境下创建了水下环境,实现了水下超高速射弹道空泡可视化仿真系统.在实际数据的驱动下,该视景仿真系统有效再现了射弹超空泡生灭的过程.

On the basis of the study of the features of high-speed underwater projectile supercavitation model,a realtime-data-drived supercavity model was built by using OpenGL programming techniques. The model was simplified by ellipse fitting principles. Multigen-Creator was used to set up a 3D solid model to and Vega Prime was used to bulid an underwater environment. Thus a Vega-Prime-based underwater visual simulation system of the high-speed projectile supercavity was developed. Drived by the realtime data, this visual simulation system can rebuild the process of formation and vanishing of the high-speed underwater projectile supercavity vividly.
