Science and technology field: This project belongs to the technical field of avionics. Main technical innovation contents: This project is based on the ldquo; universalization rdquo; needs of the DIMA platform, based on ARINC600, VITA, HB and other series of standards, summarizes and absorbs existing products on the DIMA platform, and refers to the technical level and implementation form of the same industry at home and abroad., proposed a set of universal design technologies suitable for the domestic DIMA platform. 1) The generalization indicator reaches the module level, that is, the encapsulation and interface definition of the generalization module are realized, so that the reuse level reaches the module level;2) The module maintenance process is improved to shorten the module maintenance time to 5 minutes;3) Serving the DIMA platform, the generalization definition of products under the DIMA platform reaches the installation element level, realizing the pedigree development of products under the DIMA platform; 4) Adopt design and simulation collaborative technology and introduce new heat transfer and heat dissipation methods to increase the heat capacity of the 2MCU series chassis in the MCU series to 80w;5) unify the definition of product upgrade debugging interfaces, introduce industrial design process, and improve the maintenance performance and ergonomics of the entire product. Intellectual property rights: This project studies a common structural design technology suitable for DIMA platform products, integrating& ldquo; chimney& effectrdquo; Applied in the development process of avionics, the high-heat-capacity electronic equipment cooling technology has formed, which has increased the natural convection cooling heat capacity of the 2MCU chassis under the DIMA platform by 33%. It has proposed a balance between weight, size, heat dissipation, etc. The physical packaging of the chassis and modules conforms to relevant standards of ARINC600 and VITA46/48, realizing the universal design of the chassis and modules under the DIMA platform; The introduction of the industrial design process improves product maintainability and human-machine effectiveness, reduces SRU level maintenance time by 75%, and achieves effective unification of product performance and human-machine effectiveness. Application promotion: This project has been applied to domestic DIMA platform products such as new general purpose helicopters, new unmanned helicopters, new ship-based helicopters, and ship-based electronic warfare aircraft.
