The design process of aviation forgings generally includes the following steps: Demand analysis: First, according to the functional and performance requirements of aircraft components, the demand analysis is carried out. Make clear the design objectives, working conditions, stress and load requirements of the parts. Preliminary design: On the basis of demand analysis, preliminary design. Determine the geometry, size, and structural layout of the part, taking into account relevant external constraints and connections. Material selection: According to the working environment and requirements of aviation forgings, select the appropriate material. Consider factors such as strength, toughness, wear resistance, corrosion resistance, thermal stability and weight of the material. Structural design: Detailed structural design according to preliminary design and material selection. Considering the shape, size and mating relationship of each part of the part, the design of the rod and the hole is carried out to determine the process requirements of each part. Strength calculation: Through numerical calculation or finite element analysis and other methods, the strength of the designed parts is calculated. Determine whether the strength of the parts in the working state meets the requirements, such as whether there is a stress concentration problem in the stressed part. Process design: According to the structural design and strength calculation results, process design. Determine the forging process plan, heating parameters, cooling methods, etc. Taking into account the deformation of the material, heat treatment process, dimensional shrinkage and other factors, to ensure that the parts can be precisely manufactured. Optimization design: According to the strength calculation and process design results, optimize the design. Parametric design, topology optimization and other methods can be used to find a better structure form and reduce the weight of parts. Detail design: After the optimization design is completed, the detail design is carried out. Draw engineering drawings of parts, including dimensioning, tolerance requirements, surface treatment, etc. Sample production and verification: Make samples according to detailed design, and conduct experiments or test verification. Verify that the performance of the part meets the requirements, such as strength testing, functional testing, reliability testing, etc. Product mass production: After verification, enter the product mass production stage. According to design specifications and process requirements, large-scale production and application of aviation forgings are carried out. The whole design process of aviation forgings needs to consider all aspects of structural design, strength calculation, process design and verification to ensure that the parts have good performance and reliability in the aircraft. In the design process, it is necessary to pay attention to many factors such as the selection of materials, the analysis of working conditions, the calculation of strength and the optimization of design to meet the design requirements and manufacturing requirements.
