Проектирование подкрепленных панелей авиаконструкций с вырезами на заданную усталостную долговечность

Abstract

Calculation procedure of maximum allowable by the fatigue life value o f the stress concentration factor(SCF) in reinforced airframe panels containing notches is presented. The problem of reducing the SCF in the passenger airplane wing panel with notches and holes is discussed. The problemis solved by means of interactive simulation and search for the reasonable design alternate basing on the 3D finite element model of the panel.
