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

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

Question:

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

1. Check the bundle Continuity. Add snap of result in submission
2. Add annotation to all connectors. Make an 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 is in. igs format.

The ASSIGN ELECTRICAL PROPERTIES TO CONNECTORS:required connectors are downloaded from te.com. The electrical properties are given to all the connectors using electrical part design.

1) Go to electrical part design.

2) Define the connectors by using CONNECTORS command.

3) Define the CONNECTORS CONNECTION POINT and BUNDLE CONNECTORS POINT to the CONNECTORS.

CREATING WIRING HARNESS:

1) Create the assembly of geometrical bundle product in CATIA V5.

2) Open all the required connectors into the geometrical bundle assembly product. Note that all the connectors must be electrically defined.

3) As mentioned in the figure, the connectors are placed al the required positions using the SNAP, SMART MOVE, COORDINATE SYSTEM and MANIPULATION COMMANDS.

4) Now enter into the WIRING HARNESS ASSEMBLY workbench.

5) Click on MULTI-BRANCHABLE DOCUMENT, give the branch diameter and the bend ratio. Open the route definition and connect the bundle connection points.

6) To give the routing from the main branch use ADD BRANCH POINT at the required location and give the sub-branches.

7) Now, add the corrugated tubes which are created and saved in the COT_TUBES catalog.

8) Cover all the branches with corrugated tubes. Give the extremity point from 20 mm.

CHECKING BUNDLE CONNECTIVITY:

• 1) Now in this step, we have to check bundle continuity in both Harness A and Harness B.
• 2) So for that, go in Edit>Search>Workbench-Electrical>Type-Bundle segment>Attribute-fully connected.
• 3) We will get one window, in that selecting True option will show all the connected bundle segments while selecting False option will show all the non-connected bundle segments.
• 4) Now, we will check for True condition and search for result.
• 5) All the bundle segments are showing connected. So there is bundle continuity in both Harness A & Harness B as shown in below images.

• 
• add annotations :
• 1) In this step,insert-annonation -flag tag to add annotations for all the connectors in mechanical assembly design workbench.
• 2) Annotations are used for giving connector name, functions etc.
• 3) For this, we have to select plane where annotation will be placed. In below image, we have selected front plane.
• 
• Generating CAT.part of harness Assembly :
• We have an option to genarate cat.part, click ok & Save as the file in igs format.
• 
• Conclusion :
• Sucessfully Routed the given harness layout in Electrical workbench as per given Condtions.(The Files Are Attached below in Zip format.(catalogue,cat,igs etc..,)
