What are the design principles of aircraft forgings?
The design principles of aircraft forgings mainly include the following aspects: strength and stiffness: Aircraft forgings need to have sufficient strength and stiffness to withstand various loads and vibrations generated during flight. This requires taking into account the stress state of the forgings in the design process, selecting the appropriate geometry, reasonable cross-section size, appropriate connection methods, etc., to ensure that the forgings maintain their structural integrity under working conditions. Weight and material utilization: Aircraft forgings, as an integral part of the aircraft structure, need to be as light as possible to improve the aircraft’s load carrying capacity and fuel efficiency. Therefore, it is necessary to rationally select materials during the design process and optimize the geometry of the forgings to achieve the best material utilization and weight reduction. Durability and reliability: Aircraft forgings often withstand complex working conditions and a wide range of temperature, pressure and other environmental requirements, need to have good durability and reliability. The design process needs to take into account the service life of the forging, the fatigue performance of the material, the treatment of the stress concentration area and other factors to ensure that the forging will not fail in the long-term use of the process. Assembly and installation requirements: Aircraft forgings often need to be assembled with other components, so they need to be designed with ease of assembly and installation in mind. Design elements such as the connection mode and positioning mark of forging parts should be reasonably designed to ensure the accuracy and efficiency of assembly. Manufacturability and maintainability: The design of aircraft forgings should take into account the feasibility of manufacturing and the ease of maintenance. The design needs to fully consider the forging process characteristics, production equipment capacity, process difficulty and other factors, and reasonable selection of forging methods and subsequent processing technology to ensure that the forging can be manufactured and maintained in high quality. Safety and detectability: The design of aircraft forgings needs to meet relevant safety standards and requirements to ensure safety in flight. At the same time, the design should fully take into account the detectability of forgings, facilitate non-destructive detection and monitoring, and timely discover potential defects and hidden dangers. In summary, the design principles of aircraft forgings mainly include strength and stiffness, weight and material utilization, durability and reliability, assembly and installation requirements, manufacturability and maintainability, safety and detection. Together, these principles ensure that aircraft forgings can be adapted to complex working environments while performing efficiently, safely and reliably.
