  Car fans are obsessed with good car styling, and car styling is designed to shape the ideal body shape according to the overall design requirements of the car. Automobile modeling mainly involves two aspects,science and art. Designers need to understand body structure, manufacturing process requirements, aerodynamics, ergonomics.   
 
  Car fans are obsessed with good car styling, and car styling is designed to shape the ideal body shape according to the overall design requirements of the car. Automobile modeling mainly involves two aspects: science and art. Designers need to understand body structure, manufacturing process requirements, aerodynamics, ergonomics, engineering materials, mechanical cartography, acoustics and optics. At the same time, designers need to have a wealth of artistic knowledge, such as the visual laws of modeling, painting, sculpture, design, color, and so on.  
 
  Car fans are obsessed with good car styling, and car styling is designed to shape the ideal body shape according to the overall design requirements of the car.
 
  But when buying a car not only depends on whether the car body design is beautiful, more important is to see whether the car body structure design is reasonable, whether safe, according to own car needs to make a choice. Car body structure is not just a simple shell, body structure mainly includes: body shell, window and door fittings, bumper thereof, instrument panel, seats, etc all kinds of car interior trim, ventilation, air conditioning and lights and other electrical equipment. We will mainly learn about the bearing and non-carrying bodies.
 
  Non-carrying body.
 
  The monocoque body refers to the frame carrying the whole car body, engine and body are installed on the frame, frame connected by the front and rear suspension and wheels, frames are used for fixed body of the screw hole and fixed spring of the base form of a chassis.
 
  The frame
 
  The car frame is the basic component of the supporting body, commonly known as "girder". The engine, transmission, steering and body parts are fixed. The function of the frame can be summarized as two points: one is to support and connect the parts and assemblies of the car; The second is to bear the effects of various loads in the car, such as the acceleration of the car, the longitudinal force of the braking, the lateral force when the car turns and the side slope, the impact of the bad road surface and so on. Therefore, the frame must have sufficient strength and stiffness to ensure that the vehicle is not damaged or deformed under various stresses during normal use.

  advantages
 
  The most important advantage of non-carrying body is the high chassis strength, good anti-pitching performance and the ability to bear heavy items. Due to the high strength of the frame, even if the four wheels of the car are not uniform, the body is not prone to distortion, so the driving stability and safety are good, and the noise in the cabin is low.
 
  disadvantages
 
  The body is heavy, the quality is big, the car's center of mass is high. More steel is needed to manufacture, and the cost is higher.
 
  Multi-purpose vehicle
 
  SUV, SUV, convertible.
 
  Carriage body.
 
  The car body, as its name implies, is a part of the body bearing the engine, transmission system, steering system, etc., which is borne by the frame, and bears the vibration from the ground and suspension. The shell, roof and floor of the car body, as well as the commonly known A, B, and C columns are all connected together. During the stamping stage, the steel plate is pressed into different shapes and then welded into a complete body. Most cars now use this body structure.
 
  The car body is made of various kinds of skeleton pieces and plates by welding and assembling. The industry is commonly known as "white body".
 
  advantages
 
  The anti-bending and torsional rigidity is large, the quality is small, the height is low, the assembly is simple, the high speed driving stability is better.
 
  disadvantages
 
  The noise and vibration are larger, and more serious is that when the four wheels of the car are not uniform, the body is prone to deformation.
 
  Multi-purpose vehicle
 
  Most intermediate, ordinary, and miniature cars.
 
 In addition to carrying all kinds of parts, the automobile body also plays the role of protecting passengers. The stiffness of each part of the body is different, and different types of steel are used to better protect passengers' safety when the collision is unavoidable. For example, the bumper that we know is used to absorb energy materials such as polyester and polypropylene, which will soften the impact and protect the body and passengers. In the case of the frame of the driving room (such as beams, longitudinal beams, ABC columns, etc.), in order to minimize the space of the driving room in the collision (ensuring the safety of the driving personnel), high strength materials must be used.

  In addition, it is worth mentioning that when the car is hit by the side, the door is vulnerable to impact deformation, which can damage the occupant in the car. To enhance security, in the middle of the side door car interlayer placed the two very strong beam, call it a side door anti-collision beam, like bread with a filling, only the "bread" here refers to the door. The effect is: when the side door is hit, the anti-collision beam can greatly reduce the deformation degree of the side door, thus reducing the damage of the car impact to the occupant.

  In the end, the Japanese cars are generally light and thin compared with European cars, but the Japanese cars emphasize energy absorption. The 8th generation accord USES Honda's Advanced Compatibility Engineering, which can better absorb energy and protect the crew cabin when encountering a collision. In ascension can suck at the same time, the accord development of high strength steel body structure usage increased to 48% from 13% the previous generation, the accord under the roof and floor are designed to strengthen steel, not only improve body balanced rigidity and impact performance, and high quality steel to reduce the weight of the body, also bring better handling.
