Hewing Out Evacuation Routes for Burning Buses by Linear-Shaped Charge Jet
In recent years, several buses have ignited in some cities in China, causing numerous deaths and significant property damage. However, few research studies have been conducted to deal with such accidents. Therefore, in this work, a linear-shaped charge jet with rectangular cross sections was used to hew out evacuation routes for burning buses, and the parameter design for the shaped charge jet was improved according to asymmetry limitations and human tolerance. A numerical finite element simulation model of the behavior of a jet penetrating the jambs was established using ANSYS/LS-DYNA software. The asymmetrical characteristics of an arc segment in the structure of a rectangular-shaped charge were analyzed, in addition to the influence on the deviations of the jet penetration capacity and blast injuries to occupants caused by the side effects of detonation. Furthermore, overlooking the risks posed to bystanders by the process of hewing out evacuation routes, the calculation results revealed that the improved scheme could effectively ensure the security of the near-field occupants. Barrier-free evacuation routes could be utilized within microseconds.
