Project 1

                                    PROJECT-1: ENGINE HARNESS ASSEMBLY

AIM:

• To route the wiring harness for the given engine.
• Application of all Packaging rules, Industry best practices studied in this course shall be demonstrated in design.
• Apply Protection coverings as required.

DESIGN CRITERIA AND PACKAGING ASSUMPTIONS:

• Wiring harness routing shall provide ease in manufacturing, accessibility, easy removal, and easy maintenance of attached equipment and wiring harness.
• Routing through small structural holes and openings shall be avoided, minimize chaffing and handling of the wiring harness during installation.
• Avoid the harness routing and clipping in the Blind zone of the Operator during harness assembly or in service.
• Routing shall offer protection against possible damage through common misuses such as being handhold and temporary support for test equipment.
• Provide additional slack to the harness according to the surroundings and harness bending requirements.
• Ensure the routing meets the clearance requirements with different surrounding parts.
• Avoid routing over the bolts, near to the bolted joints. It may damage the harness or puncture the harness. Keep harness away from panel mounting screws.
• Avoid harness routing near sharp edges, if not possible provide protection to the harness.
• The maximum distance between two clips on a straight branch is 200mm.
• Provide Clips and clamps if the harness is going to bend at multiple locations.
• The use of too many sheet-metal brackets should be avoided.
• The branch length should be more than 50 mm.
• Min distance between clip and branching point to be 25 mm.
• Min distance between two branch breakouts should be 50 mm.

GIVEN COMPONENTS:

ENGINE:

CONNECTORS:

C-1563689-1:

C-776438-4:

C-173090-2:

C-282080-1:

P-CLAMP:

FIR TREE CLIP:

CHENNELS:

ROUTING THE WIRING HARNESS:

     Initially whatever the selected connectors positioned on the desired area of engine. Than the bundle supports like p-clamp, for tree clip and steel brackets are provide to routing supports along with the engine.

     Than, the geomentrical bundle are converted into electrical harness assembly. After creation of bundle segment between connectors by using the Multi branchable document commant. That the bundles are should be grater then 50mm from the branching point to the connector or other components.

BUNDLE CONTINUITY CHECK :

         After create the bundle segments it would be analys the bundles are connected each other by using connectivity check in the search.

WIRING HARNESS FLATTENING:

      The routed bundles are flatten into the electric harness flattening work bench.

DRAWING CREATION:

        The flattened wiring harness is converted to drawing for manufacturing purpose.
