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

Question:-

1.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.

Answer:-

SOLUTIONS:

Step 1:

We have to first define all the connectors geometrically and electrically as shown in below images.

HARNESS B COMPONENTS:-

1.

2.

3.

4.

5.

Step 2:

Now, we have to create Harness B by using electrical harness assembly as shown in below image.

HARNESS B ROUTING with ANNOTATION

First, we will locate all the connectors at their desired position, add branch points required and create bundle segment

HARNESS A COMPONENTS:-

6.

7.

8.

9.

10.

Step 2:

Now, we have to create Harness A by using electrical harness assembly as shown in below image.

HARNESS A ROUTING with ANNOTATION

First, we will locate all the connectors at their desired position, add branch points required and create bundle segment

Step 3:

• In this step, we have to interconnect both Harness A & Harness B.
• For that, we have to create new product file and can give name as Assembly.
• Then, copy both harnesses and paste it in newly created product file or call both harnesses in mechanical assembly design as below image.

• We have to go in Electrical Assembly Design to connect both the harnesses electrically. So for that, select the option 'connect electrical devices' and both the harnesses will get connected electrically as below.
• As shown in below image, male connector should have to be inserted into the female connector.

3D Annotation for all Connectors

Step 4:

• Now, in this step we have to convert final harness assembly file into IGS format. So for that we need to follow below steps.
• Mechanical Assembly Design workbench>Tools>Generate CAT Part from product.
• Once the CAT part is created, the whole product file is converted into a single part.
• Now, whole file is converted into the IGS format and we can see all the harness assembly is looking in grey color.
• If we need to change color as before in green, we can go back and give green color to each bundle segment.

Conclusion:-

Please find the attached zip file it contains

1. part file
2. assembly routing
3. IGES file
4. CATpart file
