Cooperation of vehicle parts and components companies to promote China's automotive lightweight technology advancement

"China's auto light industry is still in its infancy." A number of experts said at the meeting.

2015 (The 9th) China International Seminar on Automotive Lightweight Technologies

To promote the development of China's automotive lightweight technology, share the development and application experience of China's own brand automotive lightweight technology, “2015 (3rd) China Lightweight Body Conference and 2015 (9th) China International Conference on Automotive Lightweight Technology “It was held in Chongqing recently. The conference was sponsored by the China Association of Automotive Engineers and the Automotive Lightweight Technology Innovation Strategic Alliance. The China Automotive Engineering Institute and CITIC Metal co-organized the conference.

Li Kaiguo, General Manager of China Automotive Engineering Research Institute Co., Ltd., said in the speech at the conference: “The China International Conference on Lightweight Technologies for Automobiles ushered in the ninth and also held for the second consecutive time at the China Automotive Engineering Research Institute. Nowadays, Quantification, electrification, intelligence and networking are the four major development directions of the automotive industry. It is hoped that companies and experts in the industry will fully communicate and communicate through this platform built by the Lightweight Alliance."

Lightweight alliance to build communication platform

Lightweighting of automobiles is a complex system engineering. Under the conditions of cost control and performance improvement, light weight structural design and light weight materials and manufacturing technologies are integrated in the vehicle products to achieve product weight reduction. At present, China's own brand enterprises have realized that the development of automotive lightweight technology requires a number of companies to join hands, with industrialization projects as a bridge, and with the principle of technology sharing, focus on R&D resources, collaborate, and promote innovation to achieve mutual prosperity and common prosperity. This is also the significance of establishing a lightweight coalition. “Since the establishment of the Strategic Alliance for Automotive Lightweight Technology Innovation, more and more vehicle and component companies have actively joined this organization and our team has been continuously expanding. At present, there are 17 members and 37 partners in the lightweight alliance. It covers the major self-owned brands of vehicles and lightweight technology companies in China, said Zhang Ning, deputy secretary-general of the China Association of Automotive Engineers and Secretary-General of China Automotive Light Weight Union.

The Lightweight Alliance is actively working on a research roadmap for the lightweighting of passenger cars, involving a total of 136 project groups, and organizing and launching the “First Automobile Lightweight Technology Salon”, “China Lightweight Auto Body Conference” and “China's Lightweight Vehicles. Technical seminars, etc., also issued 19 technical specifications and five to be released for the needs of enterprises. Since the beginning of this year, the Lightweight Alliance has launched light-weight technology and product tour activities, and organized light-weight technology parts and components companies at home and abroad to provide full-scale lightweight solutions for vehicle companies, and to carry out technical exchanges and cooperation with vehicle manufacturers.

The China International Automobile Lightweight Technology International Symposium took the form of a combination of the main venue and four sub-venues, and established more than 50 professional speeches for high-strength steel, connection technology, non-ferrous metals, and non-metallic materials. Participating companies include a number of foreign companies and research institutions such as Magna International and the University of Queensland.

Lightweight national strategic position continues to improve

To promote the progress of automotive lightweighting, it is possible to rapidly improve the development capabilities of self-owned brand cars. The China Lightweight Auto Body Conference held three times in succession shows that the self-owned brand vehicle companies have attached great importance to the industrialization and application of lightweight technologies. From a national perspective, the strategic position of “lightweight” continues to increase.

Lin Yi, General Manager of SAIC (Beijing) Automotive Lightweight Technology Research Institute Co., Ltd., said that "Made in China 2025" proposed "energy saving and new energy vehicles" as a key development area, and listed lightweighting as an energy conservation and new energy vehicle development goal. The core technology. In the industrialization of new energy vehicles, emphasis has been put on the lightweight research and application of chassis systems. In respect of energy-saving vehicles, the use of lightweight materials such as aluminum alloys, magnesium alloys, high-strength steels, plastics, and non-metal composites, as well as lighter weight, lightweight chassis, powertrain, and lightweight design of core components are promoted. “Made in China 2025” proposes “to perfect the manufacturing innovation system that combines enterprise-oriented, market-oriented, and government-industry research.” China’s auto industry has established a strategic alliance for automotive lightweight technology innovation and has carried out a lot of work. Promote a good platform for the production, research, and group standards development.

Since the beginning of this year, the National Development and Reform Commission, the Ministry of Science and Technology, the Ministry of Industry and Information Technology, and the National Development Fund Committee have successively issued special plans and notices that have repeatedly mentioned specific requirements for the development of lightweight technologies. At present, the material science for light weight is listed as the three scientific issues of new energy vehicles together with the electric science-oriented energy science and intelligence-oriented information science. The Ministry of Industry and Information Technology has started and is preparing a number of support projects related to lightweighting.

Lightweight Development Needs Industrial Planning Leading

The major forums of the International Seminar on Automotive Lightweight Technologies presented the characteristics of strong persuasiveness, skepticism, and strong learning. This indirectly reflects that although the overall direction of application of lightweight technology in all companies is the same, it is actually applied. There is still a big difference in degree and effect, and the level of lightweight technical personnel is uneven. "China's auto light industry lacks sophisticated composite material engineering design experience, serious lack of material performance research data, lack of engineers who are both familiar with the automotive structure and understand the design of new materials, and lack of new materials analysis standards and failure criteria and test verification methods. "China Synthetic Resin Supply and Marketing Association Secretary-General Cheng Zheng pointed out in his speech.

Lin Yi proposed three suggestions for the development of the automotive lightweight industry. First of all, it is recommended to improve the construction of lightweight data in the industry as soon as possible, including the material database, parts library, process library, standard library, knowledge base, and expert database. Then, it is recommended that the formulation of lightweight vehicle specifications be improved as soon as possible, and lighter The new requirements for the development of norms, the standard has been improved in the national standard or standard, but also the integration of different companies in the use of standards; Third, it is recommended to establish a lightweight vehicle evaluation system as soon as possible, divided into passenger cars, commercial vehicles and lightweight Cost analysis techniques.
