Analysis of passenger safety in the crash environment

With the development of aviation technology, people have increasingly high requirements for the safety of air transportation. This article takes civil aircraft passengers as the research object, and combines relevant research to formulate evaluation standards for passenger injury in crash environments. Taking a kind of civil aircraft as an example, the finite element method is used to simulate the passenger injury situation at different positions inside the civil aircraft in crash environments, and combined with the evaluation standards, the safety issues of passengers in crash environments are studied. The results indicate that under the protection of the fuselage frame section, all parts of the occupants did not reach the damage threshold during the 6. 1m/s crash condition. However, during the collision process, some body parts of the passengers are more susceptible to damage, and relevant parts should be protected during the collision process.
