Project 1

Objective:

• To Route the Wiring harness on Given Engine and Prepare flatten view drawing in CATIA V5.
• Application of all Packaging rules, Industry best practices studied in this course shall be demonstrated in design.
• To Check the harness Continuity using search option in CATIA V5

Given DATA:

The Engine DATA was downloaded and it is saved as a seperate Part. Then a new product file is created and a geomentric bundle is created as a sepertae product file and engine file is inserted in the same product file.

Wiring harness Fundamentel Rules:

• Bundle segments were created in such a way that the bundles shouldnt foul with the surrounding parts.
• A 2 percent slack is added to every bundle segment so that it compensates for the manufacturing tolerance
• Proper mounting clips are placed wherever required, so that wires wont be dangling in the air.
• To mount the clips, holes are drilled in the respecctive positions. These information should be conveyed to the manufacturing team , where the holes are drilled.
• When routing near the Exhaust Manifold regions, Protective Coverings should be seleccted according to max temperature ratings.
• A protective channel is placed near the manifold region to protect the bundles from excess heat and radiation.
• A miniumum clearnce of 20 mm is maintained between the bundle segment and the surrounding parts.

The first step in wiring harness design is to identitfy the components to be used and placing them in the respective positions.

Once the components are identitified , we have to to electricaly define them in the electrical part design. Connector connection points and bundle connection points are defined in the connector. Next step is to route the bundles by connecting the connectors in electrical harness assembly design. We can verify the bundle contiuity by clicking on edit>search icon and selecct the condition to be false. By doing so, we can identify the bundles which are nor connected together,

Once the geomentric bundle is created, electrical flatening should be done in the flatening workbench. First we have to define the flatening parameters and select the geomentric bundles,
