Abstract

For the realization of the aircraft to reduce weight and improve efficiency, thin-walled structure is widely used in aerospace vehicle. Thin-walled structure under the extremely harsh environment- high temperature and high acoustic loading- can cause strong nonlinear large deflection vibration characteristics, which leads to structural fatigue failure occur prematurely. According to the basic theory of finite element, this paper calculated the dynamic response of thin-walled stiffened structures in uniform temperature field under the gaussian white noise loading. According to the calculated stress, the thin-walled stiffened structure stress characteristics are analyzed.
