重大工业事故应急响应三维仿真虚拟人模型研究

Virtual Human Model for 3D Simulation of Emergency Response of Major Industrial Accidents

重大工业事故发生后,高效的应急响应能极大地减少损失,仿真分析方法在应急培训、应急预案制定以及应急决策等方面都具有重要作用。对重大工业事故应急响应三维仿真进行研究,提出了三维仿真虚拟人模型,分析了构成虚拟人的感觉模型、决策模型和行为模型3个子模型,并对某油库区建立三维仿真环境,利用虚拟人进行了仿真分析。结果表明,所构建的虚拟人能够根据环境以及事故的影响进行决策并确定应急行为。

After the occurrence of major industrial accidents,efficient emergency response can greatly reduce losses.Simulation analysis plays an important role in emergency training,developing emergency plans as well as emergency decision-making.Three-dimensional simulation of the emergency response for major industrial accidents is studied in this paper,and a 3D virtual human model is proposed.There sub-models of a virtual human,feeling model,decision-making model and behavior model,are analyzed.A virtual human simulation analysis based on an oil tank area is performed,and the result shows that the virtual human can make decisions according to the environment and the impact of the accident and determine emergency behavior.
