Wiring harness design in CATIA V5 - 3D modeling Week 5 & 6 Challenge

Q1. Route the following harness layout in the Electrical workbench. Make assumptions for harness bundle diameters. Use the connectors provided. After completion of routing,

1. Check the bundle Continuity. Add a snap of the result in the submission
2. Add annotation to all connectors. Make assumptions for annotations like connect 1, 2, etc
3. Check for the bundle warning. Add snap.
4. Generate CAT.part of harness assembly and convert it in. igs format.

Harness B

Wiring harness product assembly contains-

The harness context assembly - this is the top level product file that contains the harness geometrical bundle/assembly and the wire harness electrical bundle.

Geometrical bundle - this sub level product file is the wire harness product that contains all of the harness components i.e., clips, supports, connectors, splices, grommets, annotation and actual physical bundle segments and branches.

Electrical bundle - this sub level product file contains all of the electrical circuit information.

Procedure

First we will Download connector 3D data and then convert them into electrical connector and then add them into catalogue as aconnector.

Connectors 1 c-ydts26f15-35snv001-99-3d

Connectors 2 c-dt06-3s-cp01-99-3d

Connectors 3 c-dt06-08sa-ce04-99-3d

Connectors 4 c-dt06-08sa-ep07-99-3d

Connectors 5 c-dt06-08sa-ce13-99-3d

Harness B Routing

Now we will create wire harnesses by using electrical harness assembly. In this we will proceed in following ways:_

a. Open the Electrical harness assembly workbench.

b. Insert the pre-defined connectors either through insert command or using catalog.

c. Now we will arrange different connectors in the way that is pre-defined in the challenge schematic by using the manipulation command in assembly workbench.

d. Now define product as Geometrical bundle.

e. Now we will use multi branchable document to create wire harness to connect different electrical connectors.

f. Now we will apply protect covering on wire harness by using protective covering.

Harness A

Connectors 7 c-1-174357-2-e-3d

Connectors 8 c-dt06-08sa-ce01-99-3d

Connectors 9 c-dt06-08sa-ep07-99-3d

Connectors 10 c-ydts26f15-35snv001-99-3d

Routing Harness A

Now we will connect harness B and harness A by using the electrical assembly workbench

Then we will check the connectivity of the wire harness by using search command

when we put attribute criterion fully connected = FALSE , it will give a list segments which are not connected or showing error, if any arries

when we put attribute criterion fully connected = TRUE , it will give a list segments which are properly connected.

Annotation

Now to provide annotation, we will switch to assembly design workbench.

First we will define plane on which all annotation will be arrange

Now we will use flag note with leader to show annotation.

Converting CATpart file into igs file.

Check for the bundle warning
