Research on Influencing Factors of Automobile Parts in Autom

With the rapid development and technological progress of the automobile industry, the automobile, as an indispensable part of modern society, plays an increasingly important role in people's daily life. As the basic unit of the automobile, the automobile parts are directly related to the key indicators such as the overall performance, safety and comfort of the automobile. Therefore, the research on the influencing factors of automobile parts not only has theoretical significance, but also has practical application value.

First, material selection

Material is one of the key factors that determine the quality of automobile parts. Different materials have different physical and chemical properties, such as strength, hardness, wear resistance, corrosion resistance and cost-benefit ratio, which will directly affect the quality and use effect of the final product. For example, high-strength steel and aluminum alloy are widely used in car body manufacturing because of their excellent mechanical properties; Plastic parts are often used in the production of interior parts because of their lightweight characteristics. In recent years, the concept of environmental protection has been deeply rooted in people's hearts and the new energy automobile industry has risen. Composite materials (such as carbon fiber) have been paid more and more attention and have been applied in high-performance sports cars and electric vehicles.

Second, the design structure

Reasonable structural design can effectively improve the functional performance of parts, reduce the failure rate and prolong the service life. For example, the design of engine piston ring needs to consider its sealing and heat dissipation ability; Tire tread should not only be beautiful and generous, but also ensure good grip and drainage function to ensure driving safety. In addition, with the development of intelligent trend, more and more electronic control systems are integrated into the interior of automobiles, which requires that small accessories such as connectors and sensors must have the characteristics of high precision and strong stability.

Third, the processing technology

Advanced processing technology and equipment can improve production efficiency and reduce rejection rate, thus reducing costs and ensuring product quality. For example, small parts with complex shapes and accurate dimensions can be obtained by means of precision casting and powder metallurgy; Large-sized components with smooth and flat surfaces can be obtained by cutting with CNC machine tools. At the same time, the application of automatic production line is also helpful to realize mass customization production mode and meet the diversified needs of the market.

Fourth, environmental conditions

Factors such as temperature change, humidity level and dust pollution in the working environment may adversely affect some specific types of automobile parts. For example, under extremely cold conditions, rubber products are easy to harden or even crack; The decrease of oil viscosity in high temperature environment may lead to poor lubrication and other problems. Therefore, the climatic characteristics of the target market should be fully considered when selecting materials, and corresponding measures should be taken to protect them.

To sum up, from material selection to design and manufacture to later maintenance, every link may become an important factor affecting the performance of auto parts. Only by comprehensively and deeply analyzing these problems can we provide strong support for improving vehicle quality and promote the sustained and healthy development of China automobile industry.
