The aircraft is faced with complex and uncertain aerodynamic load environment. In this presentation, a large-scale dynamic topology optimization method considering random exciting response is developed to reduce the vibration of aircraft structures. Several numerical examples including an aircraft wall panel demonstrate the effectiveness of the proposed method.
