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

Aim:

1. Route two electrical harnesses per the given layout and interconnect them as a single harness assembly
2. check for bundle continuity, and bundle warnings, and then provide annotations for the final harness assembly.

Objective:

1. The objective of this project is to first route the two Harness A and Harness B as per the given harness layout.

Figure 1: Shows the layout of two Harness A and Harness B

The electrical connectors are represented by numbers in the above figure. There are 8 different types of connectors at 10 different locations. All connectors are added in catlog after defining them electrically to use them after.

1. First step is to define all connectors electriacally, add them in mechanical assembly first constrain them properly then define them as electrical harness assembly by using geomtrical bundle option.
2. Bundle continuity has to be checked for the two created harnesses.
3. After the two Harnesses are created, the next objective is to have them interconnected electrically.
4. Check for bundle warnings in Harness A and Harness B.
5. Add annotations to all the connectors in Harness A and Harness B.

Step-1:

Define all the electrical connectors geometrically and electrically so that they can be used in the wiring harness.

CATLOG FILE IS THEN CREATED AND ALL 8 CONNECTERS ARE STORED IN IT TO REUSE THEM USING "STORE DEVICE" OPTION INSIDE ELECTRICAL PART DESIGN. WE HAVE TO PLACE THEM IN 10 DIFFERENT LOCATIONS.

HARNESS A

To Place Connectors Properly I have created skeleton of Harness A and Dimensions are assumed.

All Connectors from 6 to 10 are added in single assembly File and are constrained

Then Start Routing the bundle

HARNESS B

Skeleton For Harness B

All Connectors from 1 to 5 are added in single assembly File and are constrained

Then Start Routing the bundle

1.Now we have 2 Harnesses

2.Harness A & Harness B and we have to create assembly between them

3.Create another Assembly

4.In it add Harnesses A & B and constrain mating faces using Surface contact and coincidence commands in mechanical assembly.

5. to make in eletrically defined use Geometrical Bundle option.

ALL FILES ARE ADDED IN A SINGLE ZIP FILE ATTACHED BELOW
