Projecting of wiring harnesses for vehicle cabling
KABI 4.6 - the integrated process chain KABI is a CAD/CAE product offering comprehensive support for the design of wiring harnesses for vehicle wiring. Design is an integrated solution using KABI, from creating the electric circuits through the schematic wiring harness diagram to the production documentation (bill of materials, wire lists, cutting lists, formboard diagram, etc.).
With the aid of the interfaces to 3D-engineering CAD systems, PPS systems and cable production and testing machines, processes can be modeled completely for both the car manufacturer/engineering department and the supplier/cable assembler. However, there is also the option of utilizing only part of the KABI functionalities – e.g. purely production-oriented design without a circuit diagram.
The functions in detail Circuit diagram The basis for the production of a wiring harness is the electrical circuit. Its functioning is generally represented in electrical engineering as a circuit diagram. Necessary switching elements are represented as symbols and can also be selected via a graphics tablet and fixed in the diagram. Connection texts and technical data are automatically stored by means of allocation to a defined component. The symbols are then connected by lines in accordance with the circuit. Wire numbers and types are also allocated at this stage. The wires are managed online via the Wire Manager.
Overview diagram Because the electrical circuit is not always available for manufacturing wiring harnesses, design may also begin with a very simple overview diagram. The circuit diagram is not required in this case. The exact wiring arrangement is not important, only the devices and connectors utilized are defined.
Excel/CSV import If the electrical circuit is unknown (e.g.: data from other systems), you may also begin with a CSV import of a wiring harness. This from-to information forms the basis for creation of the KABI wiring harness diagram
Topological diagram The topological wiring harness diagram (topological diagram) is used for clearly representing the wiring in a complete vehicle. It was specially developed for an early planning stage of vehicle wiring, i.e. lengths and structures can be noted and tubes/distributors can be dimensioned at a very early developmental stage. In this way a very early wiring harness cost assessment is possible.
