Application analysis of material technology in modern aviation manufacturing
1. Application of materials in modern aviation manufacturing industry.
At present, aviation equipment is developing in the direction of light weight, that is, the material must have high strength and the material must be as light as possible. This is related to the working environment of the aerospace industry and the product and the various task requirements that the product completes. In this way, we will use a large number of high-strength and light-weight materials, such as titanium alloy materials, carbon fiber. Due to the large amount of heat generated by the high-speed flight of the aircraft, various heat-resistant materials, such as heat-resistant coatings, metal ceramics, etc., are required. In order to prolong the airborne time of the aircraft, achieve better tactical effects, and improve the energy efficiency ratio, it is necessary to research and apply future superconducting materials, graphene materials, and stealth materials. In addition, nano-scale large-scale integrated circuits and related electronic products are used in electronic equipment to improve the efficiency of processing information; airborne detection equipment is used to detect distances.
2. Application of Robot Technology in Modern Aviation Manufacturing Industry.
At present, my country's industrial robots mainly meet the domestic market, and are mainly used in the automotive industry, including complex industrial operations such as welding, testing, handling, grinding and polishing, and assembly. There is still room for development and market prospects in other fields. We can seize the support for industrial robots and aviation manufacturing in the "China 2025 Plan" and the national "Thirteenth Five-Year Plan". Combining their own characteristics, we will develop robotics and CNC machine tool technology in the aviation manufacturing industry, so that they can give full play to the advantages of robotics in manufacturing and aircraft assembly, and improve the quality and efficiency of aviation products.
3. Application of high-speed machining technology in modern aviation manufacturing industry.
High-speed cutting technology has significant advantages such as high processing efficiency, low cutting load, less cutting heat introduced into the workpiece and small processing deformation.
There are many thin-walled parts and difficult-to-machine materials in aircraft structural parts, which are easily deformed during processing. Aviation parts are complex, their machining allowances are large, and the dimensional accuracy and surface roughness quality of structural parts are relatively high. High-speed machining of aircraft thin-walled parts helps to reduce cutting force, reduce cutting deformation, and improve machining accuracy and machining efficiency. During high-speed cutting, the chip discharge speed is fast, and the chip can take away most of the cutting heat, which improves the heat dissipation efficiency and reduces the cutting heat on the workpiece surface.
4. Application of 3D printing technology for modern aviation products.
3D printing technology is actually an additive manufacturing technology. With the characteristics of low cost and short cycle, it can meet the processing needs of special structures such as super large, super thick and complex cavities and small and medium-sized parts with extremely complex shapes. It has become a modern technology. It is one of the important symbols of the advanced manufacturing process of aerospace and other products.
Laser (electron beam) rapid prototyping technology for large and complex high-performance metal structural parts such as titanium alloys, superalloys and ultra-high-strength steels, using metal powder as raw materials, through laser melting and accumulation, directly from the digital model of the parts to complete the full densification and overall Near net shape of complex high performance metal parts. Compared with traditional forging technology, it has the characteristics of no forging equipment and forging die, high material utilization rate, short cycle, low cost, high flexibility and fast response. This technology has important application prospects in the development of aircraft and engines.
The American RLM Industrial Company used 3D printing technology to manufacture the "Patriot" air defense system gear components, and its manufacturing cost was reduced from 20,000 to 40,000 yuan in the original traditional process to 1,250 US dollars. General Electric uses 3D printing to make engine titanium parts, saving $25,000 in cost per engine.
The blisk is an important part of the engine. The integral blisk integrates the engine rotor blades and the wheel disc, which can simplify the structure, reduce the mass, and improve the aerodynamic performance.
