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

AIM

Route the following harness layout in Electrical workbench. Make assumption for harness bundle diameters. Use the connectors provided. After completion of routing,

1. Check the bundle Continuity. Add snap of result in submission
2. Add annotation to all connectors. Make an assumptions for annotations like connect 1 , 2 etc
3. Check for the bundle warning. Add snap.
4. Generate CAT.part of harness assembly and convert is in. igs format.

HARNESS A AND HARNESS B CREATION 

   Dwnloaded the CAD data of all the components  to route the following harness.All the mechanical components defined electrically to route the harness.

Here we have 8 connectors. open the cad data of connectors  in catia part design  workbench and create the connector connection point,connector connection axis system , bundle connection point .Then Switch to electrical part design workbench and define it as a connector also define  connector connection point and bundle connection point.

All the connectors defined as electrical connector and defined all the necessary properties to Connectors.

Created a catalog document in connector family and  stored all the connector data in catalog document .

Next create a new product in assembly workbench named as  assembly wiring harness contex .it is the top level  product file inside this product file  created geometrical bundle and wire harness electrical bundle

Geometrical bundle contains all of the harness components i.e connectors ,clip, gromets and actual physical bundle segments and branches.

Here we have 2 harness lay out , in side this geometrical bundle created two products "Harness A and Harnes B "

 The required electrically defined connectors added to the harness A and harness B .Then switch to electrical harness assembly workbench and defined it as a electrical assembly by using the tool "Geometrical bundle".

All the connectors positioed based on the reference sketch by using move options((manipulation,snap,smart move, using compass etc ) in the assembly workbench .

Multi-branchable catpart added to the harness A and B  .it contains all the bundle segments and braches .first Select the diameter and bend ratio in the brach defenition window then use  route defenition option and select the harness components to create the bundle .it automatically switch to electrical harness instalation workbench .

For creating sub-braches use "Add brach point" option in the  electrical harness instalation workbench and select the bundle and provide required length where to create the new branch.

After routing the harness  then check the bundle Continuity of both harness A and Harness B .

Edit⮕Search⮕Advanced⮕Electrical Workbench⮕Type:-Bundle Segment⮕Attribute:-Fully Connected.

Selecting the "TRUE" option in the attribute criterion it will show all the connected bundle segments and  selecting the "FALSE" option it will show all the non-connected bundle-segments.

Here TRUE option is selected to perform the continuity check.

next checking bundle warnings in the Harness A and B. Geometrical bundle warning generated due to errors in Bend radius, Bundle diameter or Vector position.If there is any erorr in the bundle segment the yellow indication will appear in the multi  branchable cat part and also in the sub tree structure .

If any error is showing .So go to bundle segment defenition and change the brach point location to solve this issue . Depending on the routing of the bundle segment we can troubleshoot  the error by adding slack or changing vector position.

Then switch to electrical  assembly design workbench , use connect electrical devices option and select the connectors(connector 5 and 6) to interconnect the harness A and harness B .

Next adding annotations for all the electrical connectors.

Annotations are used for easy identification,informatioins of components in the harness assemby .

• select the harness A and switch to assembly design workbench to create the annotations .
• select the  view from reference option in the annotation tool bar then select the required plane to create the annotation.
• Then give annotations to the electrical components by using "flag note with leader" option from annotation toolbar

Next step is Generate CAT.part of harness assembly and convert is in. igs format

• switch to Mechanical Assembly Workbench and select "Generate CAT Part from product" option in the tools to create the cat part 

With Annotations

Save this catpart in the igs format by using the save as option .give the file name and  select the "save as type" as .igs format
