Description
Summary:For ensuring occupant's survivability in case of aircraft crash accident, it is necessary to alleviate the impact load to an allowable level of the human body. This research aims to develop the analytical models for simulation of impact characteristics of aircraft fuselage structure. The numerical analysis on the sub-floor structures was executed by using nonlinear dynamic analysis code LS-DYNA3D, and the results of analytical models are evaluated using the results of crash tests of structural models.
