Abstract

Finite-element models are developed to compute deflected and vibro-dynamical modes for a system which consists of guided missile, adaptive catapult device and aircraft. The models with different complexity level are generated depending on particularity degree in structure description during various design stages. These models are used to investigate an influence on structural strength such factors as nonlinear mechanical constraints as well as elastic and inertial properties of system units.
