| 摘 要： | 针对全垫升气垫船气液介质复杂场景实时再现仿真需求,基于粒子系统原理和OSG渲染平台,考虑气垫船近场波浪高程模型、气垫船垫升系统压力及流量仿真模型以及气垫船气流场特点,提出了一种基于多模型的气垫船航行时气液介质特效仿真框架和实现方法。搭建了该技术的体系结构和实现流程,解决了不同开发环境下建立的异构模型仿真问题,并通过仿真模拟计算验证了该技术的可行性和正确性。仿真结果符合气垫船航行时的气液介质外形特征、作用范围以及气液介质产生的随机性和规律性特征,能快速逼真地实现气垫船航行时气液介质视景特效,对增强气垫船模拟训练效果具有重要的意义。

| Abstract: | To solve the real time simulation of complex scene of hovercraft gas-liquid media, based on particle system principle and OSG platform, the simulation framework and implementation method of hovercraft gas-liquid media special effect are presented based on models. The simulation method considered the wave surface elevation, the chamber pressure and vent flow and the flow field of the hovercraft. The system simulation framework and implementation process of the method which are established under different development environment are described. Then, the validity and feasibility of this method was verified by the results of the hovercraft sailing gas-liquid media simulation experiment. Simulation results were consistent with the characteristics and region of gas-liquid medium, also were in accordance with the random and regular features of gas-liquid medium. The methodology can realistically and quickly achieve the visual gas-liquid special effect in hovercraft sailing and has great significance for enhancing the effectiveness of the hovercraft simulation training system. |
