摘要：
For the demand of crashworthiness design and certification of composite fuselage section, the influences of composite skin on composite fuselage section crashworthiness have been studied. A finite element model of fuselage section with sub-floor waved-plates is developed, and the dynamic responses of composite fuselage section subjected to vertical impact velocity of 6.67m/s are analyzed in LS-DYNA, and the effects on composite fuselage section crashworthiness are further investigated by changing the ply numbers and ply angles. The failure modes and acceleration history curves of composite fuselage section under different conditions are given. The results show that the composite fuselage section crashworthiness can be effectively improved by selecting appropriate composite ply numbers and ply angles. (C) 2014 Published by Elsevier Ltd.
