Abstract

The structure of the airborne evaporation circulatory system is under the influence of the variety vibration caused by the helicopter during the long time running, which will cause the structure damage. The PSD analysis method is introduced into the random vibration analysis of the structure of the airborne evaporation circulatory system. A modal analysis of structure is carried out to obtain the modal frequency. When a acceleration PSD is loaded on the structure, stress and the dangerous position of the 1 sigma, sigma 2 and 3 sigma are obtained by adopted the software ANSYS Workbench. As the method is clear, simple calculation, it has a guiding significance for engineering application in design structure of airborne evaporation circulatory system.
