1. Structural design Structural design is a type of automobile design, which requires you to have a deep understanding of automobiles.It needs to be precise. For example, the wheelbase of the car you designed is 4200mm. Why do you need this? Do you want to shorten or lengthen? You need to know the direction of optimization.

2. The prompt message knows that the baby can't find the problem_! The problem may have been invalidated.

3. Horse-style body. The earliest car body modeling, that is, the carriage was directly transplanted to the car. In 1886, Daimler and Benz tested a 5-horsepower (1-emptre horsepower = 747 watts) and a 0.85-horsepower single-cylinder gasoline engine respectively, and successfully tested the first car. Box-shaped body.

4. Prease hand-drawn to complete the car hand-drawn concept design. This process is basically completed on the hand-drawn board and PS. Emphasise modeling, talk about plane ID diagrams, and convert them into 3D digital models.Alias is used more in this process.

5. Wedge-shaped car After a lot of exploration and experiments, the designer found a new type of car - wedge-shaped. This model tilts the whole body forward, and the rear of the body is as straight as a knife cut. This model can effectively overcome the lift. The first car designed in a wedge shape was the Stibek Abenti sedan in 1963.

Briefly describe the basic process of automobile design

The main steps of automobile design: external modeling work. Internal styling work. Preliminary research on automobiles. Product analysis report modeling design task book. Creative thinking and sketching. Drawing and expression of renderings. Make a scale-out model. Digital definition of model. Full-size model shaping.

The process and steps of automobile design include the following stages: Conceptual design stage: This stage mainly carries out the basic concept and shape design of the vehicle. The designer will first carry out creative sketch design, and then select the best plan for in-depth development. At this stage, some market research will also be conducted to understand the needs and trends of the target market.

The third step is to formulate a preliminary plan for the car. By drawing a scheme diagram and performance calculation, the technical specifications and performance parameters of the car are selected o-The last step is to formulate a design task book, which shows the shape of the car, each main dimensions, the main quality indicators, the main performance indicators and each Specific requirements such as the form and performance of the assembly.

Car design, the simple understanding is based on the number of a car model.It is required to design the appearance and interior of the car, so that it can be artistic on the basis of giving full play to its performance.

3. Overall layout sketch design: drawing the general layout of the product design project, on the one hand, is the basis for automobile modeling; on the other hand, it is the basis for the confirmation of the detailed general layout drawing, on this basis, the structure of the product is concretized until the design of all product parts is completed.Styling design: including two major parts: appearance and interior design.

4. Automobile design process Formulate product development plans Before the technical design of automobile products begins, product development plans must be formulated. First of all, it is necessary to determine the specific model, that is, what kind of car to produce.

5. First of all, sketch, outline the general outline of the car, and express the designer's design concept here. Next is to improve the sketch and add the design instructions. The third step is to describe it in detail, and the shape of the general car is determined in this part. The fourth step is the interior design.

What are the characteristics of automobile design

The general layout design is refined on the previous general layout sketch to accurately the size and position of each part.Determine the detailed structure, characteristic parameters and quality requirements of each component. Including: layout drawings of engine compartment, chassis, interior, exterior and automotive electrical appliances.

. The commonality of wide, large and luxurious American cars. This design depends on two factors: the comparative development of the U.S. economy and the personality characteristics of Americans. For example, the national conditions of the United States are vast and sparsely populated, which happens to be very different from China and Europe. American cars have enough free space to gallop at will.

Cars are driven and ridden by people, so their design must take into account this human-car relationship, that is, it should be convenient to operate and comfortable to ride. A car is a means of transportation, and its design must meet the requirements of traffic engineering.

Small details in car design

If the backrest of the rear seat can be adjusted, pull the adjustment handle or press the button to put down the backrest of the rear seat; if it cannot be adjusted, there is usually a seat backrest unlock switch on the outside of the chair headrest. At a critical moment, you can escape smoothly by putting down the rear seat and turning on the trunk switch.

Radio antenna We can often see cars with antennas on the roof. When facing low buildings or obstacles, car owners are often worried about whether they will "grab the pigtails". Since the car shell is made of metal, it is obviously unscientific to put the antenna on the car. It's so troublesome to go to the street with a pigtail.

For example, the front and rear weight ratio of a car should be kept at 1:1, so that when the car is stationary, the weight of the car is evenly distributed on the four wheels. In this case, such a design can also greatly improve the driving performance of the vehicle, such as turning and handling.

Incomparably exquisite designs on the car

There are many exquisite small designs on the car. Although they are inconspicuous, they are very practical. Let's take a look. Main pin inclination angle From the side of the car, an angle of the main pin axis forward or backward from the vertical direction is called the main pin inclination forward or main pin back inclination.

When it comes to the door design, everyone will think of Rolls-Royce. Rolls-Royce has always been independent. Whether it is an oversized body, a romantic starry sky roof, or a 75L super-large displacement, it is a symbol of its identity.

The switch of the co-driver's airbag, the child lock of the rear door, the design of the sunshade, the shoe box under the co-driver, and the indicator light of the refueling port are all exquisite designs of the car.

High-tailed fin design style, legendary designer Hariel. If you still don't know what I'm talking about, then you must have seen the car below in American movies, butt. It is indeed a fighter in the car... Including the Ford Thunderbird series and the Pontiac Firebird series, they all adopted this popular design at that time.
