摘要
针对客船应急疏散效率问题,开展了应急疏散三维模拟研究,提出有宽路网模型构建方法。研究了有宽路段的密集人群通行算法、基于距离和人流量的疏散路径搜索算法,改进了个体碰撞避让模型。以某大型内河客船为例,基于三维船舶模型抽取出有宽路段;基于语义关系,连接各层甲板的房间、餐厅、影剧院等船内空间节点形成有宽疏散拓扑网络。以疏散路径搜索算法和个体碰撞避让改进模型为驱动,实现了人员的疏散模拟。开发了客船应急疏散三维仿真系统,进行应急疏散模拟,并分析了影响疏散效率的关键因素,提出了船内布局和疏散组织的优化改进方案。
Aiming at the problems of passenger ship emergency evacuation efficiency,the three-dimensional simulation of emergency evacuation is carried out.The construction method of wide road network model is proposed.The dense crowd passing algorithm in wide road sections and the evacuation path search algorithm based on distance and passenger flow are studied,and the individual collision avoidance model is improved.Taking a large inland river passenger ship as an example,the wide sections are extracted based on the three-dimensional ship model.Based on the semantic relationship,the space nodes in the ship such as cabins,cafeterias and cinemas on each deck are connected to form a wide evacuation topology network.Driven by the evacuation path search algorithm and individual collision avoidance improvement model,the personnel evacuation simulation is realized.The three-dimensional simulation system of passenger ship emergency evacuation is developed to simulate the emergency evacuation.Based on this,the key factors affecting the evacuation efficiency are analyzed,and the optimization and improvement scheme of ship layout and evacuation organization is put forward.
