Wiring harness design in CATIA V5 - 3D modeling Week 7 Challenge

Aim: - To Define the mechanical parts electrically and the prepare bundle flattening has to be done in the CATIA flattening workbench. And the 2D drawing of the bundle with connector representation and different colour coding for a bundle with a protective covering

OBJECTIVE

To Flatten the Bundle and to create a 2D representation for the Bundle

Software

CATIA v5

INPUTS

CONNECTORS AND design Layout & Bundle

Layout

Procedure

To create the Flatten for the Bundle first check the bundle connections are Fully defines and the open the new product file and switch to ELECTRICAL FLATTENING WORKBENCH and enter the required perameters for the bundle to be flatten.

Fig Perameters for wiring harness flattening

Then click on ok and then save the file into a folder and save the Geometrial_bundle file to the same folder.

Open the two files in catia with a vertical positioning and import the geometrical bundle into the flattening file by using EXTRACT COMMAND.the bundle will be converted into flattening farmet with the (EHF)will be added to the end of the geometrical bundle.

And use the Flattening commend to flatten the bundle and save the file.

Open the new Drawing workbench and select the front view option and select the connect or a plane to be represented.and create the BOM for the wiring harness and dimensinate the bundle and save what ever the formate is required.

FIG BOM for the wiring harness

Result:- 2D representation of the wiring harness connectors, protective covering was represented into different colors.
