Therefore, relying on and fan motor bearing informatization is the only way to drive the industrialization of construction machinery, improve the quality of my country's construction machinery products, and catch up with the world's advanced construction machinery. And shorten the product development cycle, adjust the quantity and variety of products in time to quickly respond to market needs. Because all kinds of modern design methods and advanced manufacturing technologies, such as concurrent design, virtual technology,

flexible systems, intelligent processing and lean production, etc. In terms of the service life of key components, domestic engines are around 3000h, while foreign ones exceed 8000h; domestic hydraulic pumps are around 2500h, while foreign ones are 5000-8000h.　　 It is very obvious that the scientific research of construction machinery and the achievement of expected results are also inseparable from the support of information technology. The average service life of domestic machines is about 6000-7000h, while foreign machines are more than 20000h; the failure-free period of domestic machines is about 300h (some or even less), while foreign machines It reaches 500-1000h.

2. In other words, scientific research should be forward-looking. Therefore, improving the technical equipment and technological level of the construction machinery manufacturing industry is undoubtedly an extremely important guarantee for the promotion of scientific research results and the application of new products. This old and conservative concept objectively makes the scientific research of construction machinery and the popularization and use of new technologies lack the pull and stimulation of demand.

This undoubtedly increases the difficulty of construction machinery from material selection to design, processing and use, and it is also a challenging new topic for scientific research personnel of construction machinery. Design information technology can inject infinite power into product design innovation in manufacturing; business and production information technology can optimize resource allocation and management; process information technology supports advanced manufacturing technology; e-commerce and supply chain technology can promote
