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

AIM:

To Route the following harness layout in Electrical workbench. Make assumption for harness bundle diameters. Use the connectors provided.

MAIN OBJECTIVE:

• The objective of this project is to first route the two Harness A and Harness B as per the given harness layout.The electrical connectors are represented by numbers in the above figure. There are 8 different types of connectors at 10 different locations.
• Bundle continuity has to be checked for the two created harness
• After the two Harnesses are created, the next objective is to have them interconnected electrically.
• Check for bundle warnings in Harness A and Harness B.
• Add annotations to all the connectors in Harness A and Harness B.
• The final objective of this project is to convert the final harness file into IGS file format.

TASK 1:

To Define all the electrical connectors geometrically and electrically so that they can be used in the wiring harness. The images are all mention below.

So the given task 1 is completed.

TASK 2:

HARNESS A:

After all the connectors are defined, the workbench was switched to Electrical Harness Assembly where Geometrical Bundle was activated. All the connectors were routed using the Multi-Branchable Document command.

HARNESS B:

After all the connectors are defined, the workbench was switched to Electrical Harness Assembly where Geometrical Bundle was activated. All the connectors were routed using the Multi-Branchable Document command.

HARNESS FINAL ASSEMBLY:

BUNDLE WARNING:

This type of bundle warning will be displayed in my monitor while connecting the harness A & B.

There are many methods to solve this problem but i do with the simple way and it is a effective method also so i will move the connector pin to slightly upwards the error will get solved.as shown in the below figure.

CONNECTIVITY CHECK:

• Now in this step, we have to check bundle continuity in both Harness A and Harness B.
• So for that, go in Edit>Search>Workbench-Electrical>Type-Bundle segment>Attribute-fully connected.
• 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.
• Now, we will check for True condition and search for result.
• All the bundle segments are showing connected. So there is bundle continuity in both Harness A & Harness B as shown in below images.

ANNOTATIONS:

• In this step, we have to add annotations for all the connectors in mechanical assembly design workbench
• Annotations are used for giving connector name or functions or to give other parameters.
• We should make sure that the geometrical bundle is active before selecting the annotation plane.
• So after giving annotations to all connectors, the whole assembly will look as below.

To Converted as a part body and save as IGS Format:

In this last step we have to convert out Final Harness Assembly file into IGS format. In order to do this we should follow the steps as shown below.Mechanical Assembly Workbench>Tools>Generate CAT Part from product. Once the CAT part is created the whole product file is converted into a single part. At this stage, it can be noticed that all the bundle segments are grey in color. So, we will go back and add green color to each bundle segment so that they look same as the Final Harness Assembly. In the end, we can use the "SAVE AS" feature to save the CAT part file as IGS file as shown below.

CONCLUSION:

To Routing of the two electrical harnesses as per the given layout was achieved and interconnection between them as a single harness assembly was established. Both the harness were checked and corrected for bundle warnings and bundle continuity. At the very end, annotations were added to all the connectors and the final harness assembly file was converted into igs format.
