Wiring harness design in CATIA V5 - 3D modeling Week 5 & 6 Challenge
WIRING HARNESS ASSEMBLY:
In wiring harness assembly sometimes there are some sub assembly,
1.First step is to download the cad file of the requried part connector,backshell,corrugated tube,clips etc..,
2.Then, it is important to define all the components electrically and our project have to define the connector electrically.
3.For the connector we define the connector connection point & bundle entry point.
4.To define the connector connection point, we need axis for the coincidence axis and orientation axis.
5.For bundle connection point we need just point oriented on same face where bundle will faced on.
6.These are the conneector defined as the electrically with the connector connection point and bundle entry point.
HARNESS A:
HARNESS B:
GEOMERTIC BUNDLE:
Before routing, we need to add all the compponents under the geometrical bundle command then we can route over product or it will not allow the bundle definition.
After, creating the geometrical bundle the publication were added to the tree.
HARNESS BUNDLE ASSEMBLY:
1.Harness bundle consists of many individual wires into the bundle in circular formation.
2.Resultant bundle diameter of harness is sum of cross section area of all wires + area covered by air gaps.Generally, it is taken 10% of total diameter more than two wire bundles.
3.For making branches we use this command 'MULTI-BRANCHABLE DOCUMENT'.
4.After, that branch definition box will open, we have to fill the data of the bundle details like diameter, bend, radius, slack.
5.In the bottom of the box, we can see the route definition command. To select two point where we have to connect the branch.
6.Routing most of the time there are, having the sub-branches for the branches so we have to add another command known as 'ADD BRANCH POINT'.
INTERCONNECTION FOR TWO HARNESS:
1.In interconnection two harness are connected with the connector using command 'CONNECT ELECTRICAL DEVICES'.
2.When we connect two harness assembly the constraints are form in the tree.
FINAL ASSEMBLY FOR HARNESS A AND HARNESS B:
