摘要
井喷着火抢险作业的培训模式普遍存在着实地模拟危险性高、视频教学经验积累慢的缺点.有必要开发一个不受时间和场地限制的虚拟现实(Virtual Reality,VR)培训平台.利用Unity3D引擎搭建虚拟井场环境,使用粒子表面渲染和粒子系统实现井喷着火效果模拟,并建立多点源火焰热辐射模型,动态计算人员受到的热辐射伤害,以不同热辐射伤害等级划定安全范围.同时基于分层式复合碰撞体实现救援设备的人机交互和结果事件响应,完成一体化救援流程.结果表明:井喷着火时,安全距离应在 70 米以上;随着火焰倾角增加,最大安全距离都会向火焰倾向方向不同程度增大,最小安全距离会向火焰倾向的反方向不同程度减小.上述平台的开发建立,对安全救援作业有一定的借鉴意义.
Abstract
The training mode of blowout and fire rescue operation generally has the disadvantages of high risk of field simulation and slow accumulation of video teaching experience.It is necessary to develop a virtual reality(VR)training platform that is not limited by time and place.In the paper,we used unity3d engine to build a virtual well site environment,used particle surface rendering and particle system to simulate the effect of blowout and fire,established a multi-point source flame thermal radiation model,dynamically calculated the thermal radiation damage suffered by personnel,and delimited the safety range according to different thermal radiation damage levels.At the same time,the human-computer interaction and result event response of the rescue equipment were realized based on the layered composite collision body,and the integrated rescue process was completed.The results show that the safety distance should be more than 70m when the blowout is on fire;With the increase of flame inclination,the maximum safety dis-tance increases in varying degrees in the direction of flame tendency,and the minimum safety distance decreases in varying degrees in the opposite direction of flame tendency.The development and establishment of this platform has certain reference significance for safety rescue operations.
