The high toughness design and performance research of automobile forgings is aimed at ensuring the high strength and toughness of automobile parts under the load and environmental conditions in the working process, so as to ensure the safety and reliability of automobiles under different working conditions. First of all, the design of high toughness should take into account the choice of materials. Commonly used automobile forging materials are carbon steel, alloy steel, aluminum alloy and so on. These materials have good malleability and mechanical properties, which can meet the requirements of automobile forgings under high loads and complex working conditions. Secondly, in the forging process, it is necessary to reasonably control factors such as forging temperature, deformation rate and stress distribution to ensure the density and uniformity of the internal structure of the forging. The mechanical properties and toughness of forgings are further improved by heat treatment, quenching and tempering. In addition, the design process should take into account the geometry and structure of the forging, such as rounded radius, hole location and size. Reasonable geometric design can avoid stress concentration and crack, improve the toughness and fatigue resistance of forgings. Finally, it is also necessary to conduct relevant performance testing and analysis, such as tensile test, impact test and fatigue test, to evaluate the mechanical properties and toughness of the forgings. These tests can provide manufacturers and designers with important data about the reliability of forging materials and structures, which can help further optimize designs. To sum up, the high toughness design and performance research of automobile forgings need to consider factors such as material selection, forging process and geometric design, and verify and improve the design through testing and analysis. This can ensure that the automobile forgings have enough strength and toughness to meet the safety and reliability requirements of the automobile in various working conditions.
