Today, from the perspective of "automobile research and development", I will take you to see what parts of this work include.

Maybe a lot of new graduates know about automobile research and development that a designer who is full of talent will put the designed automobile model on the big screen, and the team will discuss the modification together. Finally, if there is no big problem, they can hand it over to the factory for manufacturing and mass production.

If you think so, it is too superficial. The automobile research and development work is not only the above process, but also generally includes automobile scheme design, automobile conceptual design, automobile engineering design, automobile sample testing, and automobile batch production. The process is not smooth. Take engineering design and conceptual design as an example. One of the two designs is a fine direction design, and the other is a general direction estimation design, Therefore, there is a contradiction in duration.

Let's talk about the five stages of automobile research and development.

Scheme design of automobile

The scheme design of automobiles is the basis of other working stages of automobiles. After the scheme design is determined through market research, the positioning, crowd and style types of automobiles are determined. After the determination, the similar automobiles of other brands are compared through horizontal scientific analysis. After all, the production of automobiles without market competitiveness is undoubtedly a waste of human and material resources, so the scheme design is the basis of automobile research and development.

Concept Design of Automobile

After the automobile scheme design is determined, the conceptual design stage of the automobile comes. In this stage, the designer is mainly responsible for the preliminary design, from sketches, small models to equal scale models. In addition, the cost budget must be carried out in the conceptual design stage to strictly control the cost.

Engineering Design of Automobile

Engineering design can be said to be the top priority of automobile research and development, because at this stage, the concept car should be reduced to parts and components, and each assembly should be planned and combined one by one. During this period, other parts of the company must purchase or produce parts that meet the requirements. The engineers also adjust the coordination of the whole vehicle, and study and solve the small problems of the whole vehicle one by one, meeting the requirements of conceptual design.

Test of sample vehicle

After the completion of the automobile engineering design, there is a sample vehicle that meets the design requirements, but it is still impossible to put the sample vehicle into mass production, because it is not known how the vehicle performs in all aspects.

Therefore, performance test and reliability test must be carried out for the sample vehicle. The performance test is to test the performance of each part and spare part of the sample vehicle to see whether the added spare parts meet the design requirements. The reliability test is to test the performance of the sample vehicle under various conditions, such as durability and strength under adverse conditions, extreme performance under adverse conditions, etc.

Mass production of automobiles

If the sample vehicle meets the specified indicators, the factory can develop and manufacture the mold. Then it should be put into factory production in small batches. Why not put into production in large batches at this time?

Although tens of thousands of tests have been carried out on the sample vehicle, some minor problems may not be found during the test, so small batch production must be carried out to verify the reliability of the product. If there are no major problems, mass production can be carried out.

The above five stages of "automobile scheme design", "automobile conceptual design", "automobile engineering design", "automobile sample test", and "automobile mass production" constitute automobile R&D. As automobile engineers, we may not have to participate in every stage, but as above, each stage is a link between the preceding and the following, with a basic scheme design and a big goal conceptual design, Precise engineering design and reliable sample vehicle testing will enable the final mass production of vehicles.
