With the continuous development of the construction machinery industry, the requirements for material properties and combined applications are becoming higher and higher. As a kind of lightweight and high-strength material, aluminum forgings in construction machinery have become one of the research hotspots in combination with other materials. The following will introduce some research progress of aluminum forgings combined with other materials in construction machinery.
- Combination of high-strength steel and aluminum forgings: In some parts that require structural stiffness and strength, such as body structure, force connection, etc., the combination of high-strength steel and aluminum forgings can be used. High-strength steel has good strength and toughness, and aluminum forgings have the characteristics of lightweight, the advantages of the two complement each other, and can achieve the design needs of weight and strength.
- Combination of carbon fiber reinforced composite material and aluminum forgings: Carbon fiber reinforced composite material has the characteristics of high strength, high stiffness and low density, and is an ideal lightweight material. Combined with aluminum forgings, better performance can be achieved in some parts with high strength and low weight requirements. For example, in robotic arms and rail systems, the combination of carbon fiber reinforced composites with aluminum forgings can improve the rigidity and response speed of the system.
- Combination of silicate ceramics and aluminum forgings: silicate ceramics have the advantages of high temperature stability, wear resistance and corrosion resistance, and are often used in high temperature environment and parts with large wear of construction machinery. The combined application with aluminum forgings can reduce the weight of the structure while ensuring high temperature stability and wear resistance, and improve the overall durability.
- Combination of polymer and aluminum forgings: Polymer materials have the characteristics of good impact absorption, corrosion resistance and low friction coefficient. The combined application with aluminum forgings can be used for noise and vibration control of power transmission systems, improving the reliability and comfort of mechanical systems.
The above are some advances in the combined application of aluminum forgings and other materials in construction machinery. Through reasonable material selection and combination design, we can give full play to the advantages of different materials and achieve the improvement of comprehensive performance such as lightweight, high strength and durability of construction machinery. In the future, with the continuous progress of science and technology, the combined application research of aluminum forgings and other materials in construction machinery will be more extensive and in-depth, and provide more innovative ideas and solutions for the development of construction machinery industry.
