Vehicle lightweight is an effective way to improve fuel efficiency and reduce vehicle carbon emissions. The International Energy Agency said that about 24% of global carbon dioxide emissions came from transportation, including roads, railways, aviation and shipping, of which road vehicles were the biggest "culprit".
At the macro level, lightweight can be achieved by using lightweight materials, such as titanium alloy, aluminum alloy, magnesium alloy, ceramics, plastics, glass fiber or carbon fiber composites. At the micro level, the parts can be designed more compact and miniaturized by using high-strength materials. Additive manufacturing - 3D printing technology brings space for manufacturing functional integration, compact and lightweight parts.
Honda is carrying out several projects to reduce the weight of body parts, including body frame, engine, crankshaft and bolts. In this issue, 3D science valley will share the progress made by Honda's R & D department in crankshaft lightweight. Honda has applied generative design and 3D printing technology in the project.
