Finite-Element Analysis of the Arm Lock of Ejection Seat Interlock Device

Abstract:

Analysis of the causes about the ejection seat in the ejection process, when the aircraft canopy is not throw away , ejection mechanism ignites advance. using the finite element method(FEM) to carry on the deformation analysis of the lock arm in the interlock device, defined the strength of the lowest parts of the lock arm, obtained the stress distribution graph of lock arm, which provides a theoretical reference for the interlock device on the optimal design.
