With the increase of the quantity and complexity of aerospace product development, the traditional design mode has been difficult to meet the development needs. There is an urgent need to establish a multidisciplinary and multidisciplinary collaborative design platform based on digital prototyping to improve design efficiency and quality. To solve this problem, this paper carries on the related technical research, completes the analysis, the design, the development realization and the application verification of the multi-disciplinary collaborative design platform. The main contents of this paper are as follows: firstly, the research trends of digital prototyping, multidisciplinary collaborative design platform, enterprise architecture and other related technologies are summarized from the aspects of field, technology and so on. Secondly, this paper analyzes the present situation and deficiency of the overall scheme design of aerospace vehicle, puts forward the business requirements, functional requirements and other requirements of the multidisciplinary collaborative design platform, describes the data flow among major majors, and analyzes the user role requirements and main use cases. Thirdly, based on the TOGAF enterprise architecture framework, this paper analyzes and designs the overall framework, business architecture, application architecture, data architecture and technical architecture of the multidisciplinary collaborative design platform. The business architecture describes the development process of aerospace vehicle digitization and the design process of multidisciplinary collaborative scheme based on digital prototype, and the application architecture describes the system composition, the integration relationship between systems and the main application scenarios. The data architecture describes the conceptual model, logical structure and physical structure of the data, and the technical architecture describes the development techniques of page presentation, front-end control, business logic, data access and so on. 4. Based on the technical research and overall architecture design, develop and realize the aircraft multidisciplinary collaborative design platform, explain the application interface, the platform frame and the professional design subsystem of the platform, with the overall, pneumatic, control, power, load, By demonstrating the feasibility and effectiveness of the platform and related technologies, seven professional collaborative design processes, such as structure and strength, are demonstrated for example. Fifth, the paper summarizes the research results, points out the shortcomings of the research, and looks forward to the further research direction of related technologies. In this paper, three key technologies of aircraft multidisciplinary collaborative design platform are studied. A platform framework and seven professional design subsystems are developed successfully, and seven professional demonstration applications are completed. The research results provide technical support for building a multi-disciplinary collaborative design platform for aircraft based on digital prototyping, which will play an active role in promoting collaborative research and innovation of aerospace products.
