Taking the airborne electronic equipment chassis as a carrier, based on specification chassis design requirements, analyzing the design points, integrating chassis design processes, optimizing the structural design of the chassis parts and the selection of unified chassis accessories, the design cycle is shorten and the product quality is improved effectively. So the costs of design and maintenance are reduced to realize the transformation from empirical design to predictive design, and the three modernizations level of the airborne electronic equipment chassis is improved, which provides references for the three modernizations design of the airborne electronic equipment chassis.
