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

AIM:

• To create a Wiring harness assembly and route the harness as per the given layout.

OBJECTIVE:

• To electrically define all the parts provided.
• To create wiring harness assembly and route the harness as per the given layout.

• To check for the bundle segment continuity.
• To add annotations to all connectors.
• To check for bundle warning.
• To generate the CAT.part of the complete wiring harness assembly and convert it into .igs format.

SOLUTION METHODOLOGY:

Step - 1:

• To download all the 3-D CAD data required for the above assignment and save it in the desired folder.

Step - 2:

• To identify the connector side and the bundle side and create points and axis system at the mid-point of the mating surface.

Step - 3:

• To navigate to the Electrical Part design workbench and define the electrical properties of the connector by:
  
  • First defining the part body as a connector.
  • Then defining the connector connection point.
  • And then defining the bundle connection point.
• The above steps should be followed for all the Connectors to electrically define them and use them in the wiring harness assembly.

Step - 4:

• Create a working environment platform to place the connectors easily, smoothy and in a proper orientation.

WORKING ENVIRONMENT FOR WIRE HARNESS A:

WORKING ENVIRONMENT FOR WIRE HARNESS B:

Step - 5:

• Create a new product for Wire harness A layout.
• Add all the connectors that are required for the harness layout and also add the working environment.
• Place all the connectors in their respective positions according to the given layout.

WIRE HARNESS A LAYOUT:

Step - 6:

• Create the wire routing according to the above layout.

WIRE HARNESS A ROUTING:

Step - 7:

• Checking the continuity of the bundle segments:

Step - 8:

• Create a new product for Wire harness B layout.
• Add all the connectors that are required for the harness layout and also add the working environment.
• Place all the connectors in their respective positions according to the given layout.

WIRE HARNESS B LAYOUT:

Step - 9:

• Create the wire routing according to the above layout.

WIRE HARNESS A ROUTING:

Step - 10:

• Checking the continuity of the bundle segments:

Step - 11:

• Creating a new product file to assemble both the wire harness A and B.
• Add both the Wire harness A and Wire harness B product file to the main Wire harness assembly file.

Step - 12:

• Navigate to the Electrical Assembly Design workbench.
• Select the 'connect electrical devices' and select the connector 5 of wire harness B and connector 6 of wire harness A.

ADDING ANNOTATIONS TO ALL CONNECTORS:

CHECKING FOR BUNDLE CONTINUITY:

GENERATING THE CAT.PART OF THE WIRING HARNESS ASSEMBLY AND CONVERTING INTO .IGS FORMAT:

CONCLUSION:

• From the above assignment we learnt how to create wiring harness assembly, wire routing and how to connect two separate wire harness assembly.
• We also learnt how to check the bundle continuity, give annotations to the connectors.
• We also learnt how to solve the bundle warning with different methods.
• We also learnt how to convert a CAT.product file to a CAT.part file.
