The Technical Glossary Autocom cdp pro body shell

The bodyshell is a part of the body structure, Autocom cdp pro body structure, including: bodyshell, front plate parts, doors, windows, exterior trim and internal multiplexing trim, seats and ventilation, heating, air-conditioning device. Trucks and special-purpose vehicles, including cargo boxes and other equipment.
The bodyshell is the installed base of all the body parts, usually refers to the longitudinal beams and columns and other load-bearing elements, and they connected panels composed of spatial structure, also includes the laying on sound and heat insulation, anti vibration, corrosion, sealing materials and coatings.
Force Category bodyshell can be divided into the Unibody non-Unibody and Unibody three kinds.
① non-Unibody. The body structure is characterized by the body by rubber cushions or springs and frame for flexible connection. In this case, the frame is supporting a weight basis of the entire vehicle, bear each installed on which the assembly of the various loads. Unibody body part is not carrying, at least it is to withstand the weight and inertia force of personnel and cargo loading, but not considered in the design of the frame body frame carrying auxiliary Bale. This body, if you are interested in, bent Digimaster 3  down to look at the bottom of the vehicle, you will see the back and forth throughout the two girders (Unibody will not see). The Unibody major body ladder frame (Ladder Chassis) the ladder frame Jiaozhen frame, is the earliest form of the frame.
Ladder frame looks like a ladder lying flat, two longitudinal main beams combined with many different size thickness Vice beams, sometimes coupled with inclined beams as consolidation. Unibody greatest feature is durable, high rigidity, strong ability to confront head-on collision. And because the non-fixed connection of the frame with the body, therefore, the in vertical big drop on the rough road, the twist of the vehicle by a sturdy ladder frame are absorbed, to prevent twisting of the vehicle body, which is very necessary for the off-road vehicle design. And until the 1960s, it is still the majority of car use.
Unibody advantage is independent beam chassis strength, good performance of anti-bumps In addition, the four wheels by the force  Digimaster 3 For Sale  uneven, is borne by the frame, and will not be passed up to the body, so the SUV and off-road vehicles use more. However, non-Unibody also has its drawbacks, body weight, high center of gravity and danger (such as roll-over) thick chassis also relatively weak body produce deadly threat (Unibody will not encounter this problem, its body is one). Cars from the 1950s gradually to replace the non-Unibody Unibody. Domestic low-end SUV now mostly non-Unibody This is not positioned as a pure off-road vehicles (more urban type), but technical and cost dictates.
