Research of aircraft equipment cabin layout optimization methods based on virtual maintenance

Aircraft equipment cabin layout design is an important part of aircraft design. It refers to the reasonable arrangement of each piece of equipment and component in a limited space. Currently, aircraft equipment cabin maintenance difficulties are common, time-consuming, uneconomical, and are serious maintenance problems. In order to improve the accuracy and quality of maintenance design, a virtual maintainability design method is proposed, using DELMIA as a tool to build the virtual environment, which can be used to verify and improve maintainability. The maintenance visibility, accessibility, operating space, and working gesture are treated as objective functions. The functional constraints and aircraft equipment cabin layout rules are also considered, and are formulated as constraints. Thus, a combination algorithm model for maintainability is presented. According to the characteristics of the equipment layout problem, a modified particle swarm is used to improve the computational efficiency and solution accuracy. Finally, the application of a fighter electronic cabin is studied in detail to illustrate the effectiveness and usefulness of the proposed method. The results show that virtual maintainability design can be implemented to solve the layout optimization problem.
