Project 1

WIRING HARNESS FOR V16 ENGINE

Aim : The main objective is to route a wiring harness for a V16 Engine in Catia V5.

In this project, the wiring harness will be carried out following all the standard practices and design parametres. Later, will flatten the bundle and create a draft sheet too.

Given is the V16 Engine.

Points to be considered :

• To consider 16 connectors for spark plugs, 4 for cam shaft sensors, 1 for air monitoring and 2 over crank case.
• To consider necessary clips and clamps for better routing. Make sure not to touch plastic components to engine body
• Minimum distance between branch points to be more than 50mm
• Branch length to be more than 50 mm
• Bend radius ratio value to be between 1.4-1.5
• To provide necessary slack to the bundle segments
• Avoiding scrapping with sharp edges and routing away from hot regions
• Providing necessary protective coverings like Cot tubes or cotton sleeves
• Using guiding channel where the routing needs to be precise (here spark plug points over engine head)

Steps to follow to create a harness bundle :

• Create a context assembly in Electrical Harness Assembly workbench which includes the engine body, geometrical bundle and a L-bracket for mounting of inter-connector
• Define all the necessary connectors electrically and add them into the geometrical bundle. Define them with the bundle entry point and connector connection point
• Define required P-clamps and guiding channels electrically too for support and routing. Define them with required bundle entry points
• Create branchables with suitable diameter and bend radius and provide adequate slack to them
• Cover the bundles with protective coverings like Cot tubes and cotton sleeves
• After connecting all the connectors, check for bundle connectivity. If fully connected, can proceed for flattening
• Create a flattening of entire harness in Electrical Harness Flattening workbench
• Switch to Drafting workbench and create a flattened drawing of the same
