Fundamentals of Unibody Construction - Rahmen Structure
|
|
|
|
|
Rahmen structure is a framework structure constructed by the individual parts assembled together with rigid fixed points (rigid joints). When the body takes external forces, it resists them as one unit because the component members are rigidly joined. A unibody is made up of a series of connected rahmen structures. | | |

A unibody is a combination of a number of rahmen structures that are assembled into one with spot welding (rigid points) connecting their component parts. It is designed and manufactured so that, when the body takes forces such as load intruded by: |
|
|
|
? |
Starting, acceleration and braking | |
|
|
? |
Impact from the road surface | |
|
|
? |
Bending and twisting (body deformation) during cornering
|
|
|
|
The unibody resists those external forces by dispersing across the entire body structure. | |
|
|
|
|
The unibody ensures sufficient strength and rigidity by: |
|
|
|
? |
Carefully designed structural members such as frames and crossmembers. | |
|
|
? |
Thin sheet parts such as skins and panels and reinforcement parts. | |
|
|
|
|
During unibody body repairs, it is important to fully understand the characteristics of Rahmen structure. These characteristics determine how far impact damage traveled through the vehicle’s body. It is likely that damage may even exist opposite the actual impact area. | | | |
