Project 2
Aim
Assumptions
1. provide clips/clamps as per requirement.
2. make sure that there is no fauling case while designing wire harness. additional clips/clamps can be used to avoid these problems.
3. give proper additional stacks if required.
4. avoid routing on sharp edges or else provide protection over the harness.
5. follow the clarance distance and keep away the harness from heat generation components.
6. protection should be provided as needed as per surrounding temperature.
7. branch length should be greater than 50mm.
8. minimum distance between two branch points should atleast 50mm.
9. minimum distance between clip and branch point should be atleast 25mm.
10. if packaging area is too tight and there are many packaging constraints then we can think of creating harness channel which can be used to route and protect the wire harness effectively.
we have to define all the connectors as well as clips geometrically and electrically
Furr clip
p clip
steps for routing
1. define all the connectors as electrical components and the clips as the supporting equipment.
2. position all the connectors,clips and guiding channel at the desired location.
3. now by using multi-branch bundle route all the connector with the clip and clamp.
4. create a catalogue and add the protection covering of various diameters.
5. now using protection covering tool protect all the bundles.
6. create a gap fron end and start exrimity 10 to 20mm.
checking bundle continuity
. in this step , first we have to make sure that multi-branchable is selected then we have to go in
Edit>search>advanced>workbench-electrical>type-bundle segment>attribute-fully connected.
. by selecting 'true' option will show all the connected bundle segments while selecting 'false' option will show all the non connected bundle segments.
. here we selected true so it shows all the connected bundle segments.
.creating flatten view of the engine harness geometrical bundle assembly
in this step , for creating flatten view we have to work in electrical harness flattening workbench of catia V5. we should also make sure that the flattening file is saved in the same folder where other files of harness assembly are saved.
. before creating flattening we have to define all the flattening parameters
creating a flatten view drawing for wiring harness assembly
in the flattening operation we already created given the parameters required for 3D drawing , so we have to inseet the front view of flattening product to the drawing file. it should be noted that in 'dress up' settings 3D wireframe is always on . if this setting is not selected then the bundle segments won't be visible on drawing view.
conclusion
routing of wiring harness for car door assembly has done and prepared the flatten view drawing in catia v5 . applied all the packaging rules while routing the wiring harness, implemented industry best practices in the harness design.
