| 中文摘要:为进一步提高液化天然气(liquefied natural gas,LNG)罐柜内河运输的安全性，研究LNG罐柜在船上装载位置的合理性。根据爆炸产生的火球模型和热辐射模型，考虑人员受到不同程度伤害的概率，建立LNG罐柜爆炸危害的系统动力学模型。利用系统动力学仿真软件Vensim_PLE模拟2个罐柜爆炸，得出结论：爆炸中心的热辐射强度最高，但在距爆炸中心一定距离处人员受到伤害的概率最大。为保证人员安全，船舶罐柜装载区与人员活动区应保持足够的安全距离。 |

| Abstract: In order to further improve the safety of LNG tank transportation in inland rivers, the rationality of loading position of LNG tanks on ships is studied. According to the fireball model and the thermal radiation model, where the fireball and thermal radiation are produced by the explosion, the system dynamics model of the explosion hazard of LNG tanks is established considering the probability of different degrees of injury to the crew. Using the system dynamics simulation software Vensim_PLE to simulate the explosion of two tanks, it is concluded that the thermal radiation intensity of the explosion center is the highest, but the probability of crew injury is maximum at a certain distance from the explosion center. In order to ensure crew safety, a sufficient safe distance should be maintained between the tank loading area and the crew activity area on a ship. |
