Lightweight automotive transformation begins with suspension

In recent years, automobile weight reduction has become an important issue for the world's auto industry. Under the pressure of energy conservation and emission reduction and improvement of fuel efficiency, it is increasingly showing a trend of lightweight development. Suspension system as one of the important parts of the car body, how to achieve light weight has become a non-negligible problem in the development of the vehicle, various types of rubber suspension, less leaf springs, aluminum swing arm, new material applications, etc. More and more applications have been applied.

The electronic, but also with the continuous improvement and improvement of vehicle structure and function, study of automotive vibration, design of new suspension electronic control system, the vibration control to the lowest level is an important measure to improve the quality of modern vehicles. At present, automotive suspension systems have entered the era of control using electronic controllers. The use of better control methods to obtain high-performance vibration reduction effects and make the energy consumption as low as possible is the main direction for the development of automotive suspension systems.

In 2013, the “2013 Second China Automotive Suspension System Industry Development Forum” organized by China Automotive Consultation Center and organized by Shanghai Jiazhidao Automobile Consulting was held in Shanghai. The forum will discuss suspension system matching technology and structural innovation, suspension performance optimization and electronic control technology, and suspension lightweight design and materials.

Lightweight, who will preempt the competition?

What is the weight of the car? In fact, car lightweighting is to reduce the car's trim quality as much as possible while ensuring the car's strength and safety performance, thereby improving the car's dynamic performance, reducing fuel consumption, and reducing exhaust pollution. Experiments have shown that if the vehicle's vehicle weight is reduced by 10%, the fuel efficiency can be increased by 6%-8%; for every 100 kg of vehicle's curb weight, the fuel consumption per hundred kilometers can be reduced by 0.3-0.6 liters; the weight of the car can be reduced by 1%, and the fuel consumption can be reduced by 0.7. %. At present, due to the need for environmental protection and energy conservation, the lightweighting of automobiles has become the trend of the world's automobile development.

Lightweight does not mean cutting corners. It is not just a simple body or light weight of a car part. The report on “Lightweight Significance of Automobiles” issued by China Automobile Association has pointed out that the overall structure of automobiles should be analyzed and optimized, and the simplification, integration, and lightweight of auto parts should be realized; the weight of the engine should be reduced; and the transmission should be lightweight; Suspension lightweight; lightweight body and accessories lightweight are currently achieving six aspects of vehicle weight reduction.

Guo Shuowen, a researcher of automotive technology and industrial development at North China University of Technology, said in an interview that China’s automotive lightweight technology is facing two major difficulties in research and development. On the one hand, we must break the barriers between the numerous disciplines involved in the development of lightweight technologies and form a comprehensive and systematic knowledge system. On the other hand, the state should play a role in making strategic and forward-looking deployments. The forum will invite experts from Mr. Wang Hui from Shanghai Benteler Automotive Systems Company to give professional explanations.
