Influenced by the unique car culture in China, many consumers think that Japanese cars are light and invulnerabte. This statement can be said to be quite profound. Scientific research shows that the safety performance of the vehicle is not directly related to the weight of the vehicle, the safety of the vehicle depends on the performance of the body structure and the body structure. Moreover, in recent times in the domestic fire in the Research Center, the crash results also confirmed the body “lighter” Japanese cars, but more safe.
At the same time, the safety strength of the body structure is not directly related to its own weight. Such as the common aluminum alloy and steel plate materials in cars, aluminum alloy although lighter, but its strength is much higher than the steel plate material, but also more resistant to impact.
Therefore, the Japanese car light can not withstand the collision of unsafe claims are naturally untenable. On the contrary, the body light also has many advantages. The most important point is to be able to optimize fuel consumption and electric vehicle energy consumption performance, which is one of the major car companies are striving for body weight.
Recently, according tomedia reports, Honda’s research and development department and software company Autodesk to cooperate, the two sides designed a crank shaft components and 3D printing technology to manufacture samples, in order to achieve vehicle lightweight and improve engine fuel economy.
Crank shafts play a key role in automotive engines, and the component is highly demanding for wear resistance due to its ability to convert piston swings into rotating forces. The crank shaft must be shaped to withstand combustion pressure and maintain a rotating balance at all times.
Because of the material and manufacturing process specificity of crankshaft components, the overall structure of the crankshaft has not changed much since the birth of the engine. Now, with the application of 3D printing technology, Honda’s design will achieve a 30% weight loss goal compared to the aforementioned products, which can be said to be a new breakthrough.
In addition, Honda has been working on 3D printing technology and intelligent design solutions to optimize the design of automotive components. To date, Honda has upgraded a number of automotive components, including seat belt holders, engine control units and frames, and has used 3D technology to achieve lightweighting of body parts.
