2. Abstracts or Introduction
Abstract-With the continuous improvement of people's living standards, mobility tools have also evolved from walking and cycling to today's private cars. The rapid increase in the number of private cars has caused China's energy consumption to increase. China does not have sufficient energy resources. In order to alleviate the pressure on energy, the energy conservation and emission reduction of automobiles must be paid attention to. There are many ways to save energy and reduce emissions of automobiles. One of them is to reduce the weight of the car. Once the weight of the car is reduced, the amount of energy consumed will be reduced, thereby achieving the goal of energy conservation. Based on this, this article focuses on the use of lightweight materials in current automotive materials, and introduces a variety of lightweight materials in detail to help cars reduce weight, reduce energy consumption, and achieve sustainable development in the automotive industry.
3. Research Background:
Background of the Research Topic:
Cars have become a necessary means of travel, and the increasing number of private cars reflects national economic improvement. However, this increase also leads to more serious pollution and energy shortage problems. "Automotive lightweighting is the development trend of the scientific development concept and the corresponding national call for energy conservation and environmental protection". This involves replacing traditional automotive materials with lighter materials to reduce vehicle weight and energy consumption. The development of automobiles depends on the "renewal and iteration of automotive materials", and applying lightweight automotive materials is key to achieving lightweight automobiles.
Status of Existing Research:
Common automotive materials are mainly glass, plastic, steel and aluminum alloys. Steel accounts for about 70% of the weight of automobiles, while aluminum alloy and other materials account for about 10%. To realize weight reduction, special materials must replace steel. Lightweight automotive materials are widely used, and their application can improve the scientific development of the automotive industry by ensuring vehicle performance.
Necessity of the Research:
The rapid increase in private cars in China has led to increased energy consumption, while China lacks sufficient energy resources. Energy conservation and emission reduction in automobiles are crucial. Reducing vehicle weight is an effective method for energy saving and emission reduction. This research focuses on the application of lightweight materials in automotive materials to address energy consumption and promote sustainable development in the automotive industry.
