Integrated Structure Design and Analysis of a Carbon Fiber Cabinet for Airborne Radar

During takeoff, landing and flight, the airborne radar has to endure a variety of vibration and shock. Due to the complicated environmental conditions, the structural components of radar need to be well designed. Radar cabinet is a typical part of avionics. Its main function is to connect, tighten and support airborne electronic equipment. It is the guarantee of normal operation of airborne electronic equipment. Because the airborne equipment may be subject to worse mechanical vibration, and the weight reduction requirements, the cabinet is required to be designed in lighter weight and higher reliability. In this paper, a carbon fiber integrated forming cabinet is introduced. The structural design of a complex carbon fiber cabinet is described. Through mechanical simulation analysis, the mechanical properties of the carbon fiber cabinet under airborne vibration and impact conditions are studied. The high reliability of the carbon fiber cabinet is verified by strain test and other relate experiments. The research of this paper has an important reference for the lightweight design of airborne radar cabinet.
