【摘要】：受限空间油气泄漏爆炸会产生巨大的能量,爆炸碎片在抛射距离和抛射方位上具有很大随机性,引发的多米诺事故容易对设备和人员造成重大伤害。为了研究爆炸碎片的影响范围及对设备、人员伤害程度,以地下密闭涵道作为研究对象,考虑爆炸能量影响,采用ANSYS Autodyn模拟软件,重点对涵道覆盖物爆炸碎片进行模拟,定量分析了爆炸碎片的影响范围及在影响区域内对设备、人员造成的伤害程度。结果表明:运用Autodyn软件进行仿真,能够更加准确地得出爆炸碎片的抛射情况及影响范围;在爆炸能量一定的情况下,碎片的大小是影响设备和人员受伤害程度的重要因素。
[Abstract]:The explosion of oil and gas leakage in restricted space will produce huge energy, and the explosion debris has a lot of randomness in the ejection distance and the ejection direction. The domino accident caused by the explosion is easy to cause serious harm to the equipment and personnel. In order to study the influence range of explosion debris and the degree of injury to equipment and personnel, taking the underground closed ducts as the research object, considering the effect of explosion energy, the impact of explosion energy is considered, and the simulation software of ANSYS Autodyn is used to simulate the explosion debris of tunnel coverings. The impact range of explosive debris and the degree of injury to equipment and personnel in the affected area are quantitatively analyzed. The results show that the ejection of explosive debris and its influence range can be obtained more accurately by using Autodyn software, and the size of debris is an important factor affecting the injury degree of equipment and personnel under the condition of constant explosion energy.
