AIM :
To Route the Wiring harness on Given Engine and Prepare flatten view drawing in CATIA V5. Application of all Packaging rules, Industry best practices studied in this course shall be demonstrated in design. Apply Protection coverings as required.
INTRODUCTION :
A wire harness, also commonly referred to as a wiring harness, is an exterior sheath used to cover some types of electronic wires. Generally, wiring harnesses are made of thermoplastic or thermoset materials that can help protect the cables from the environment.
OBJECTIVE :
The objective of the project is to route the wiring harness on given Engine and prepare flatten view drawing in CATIA V5. All types of packaging rules have to be considered while routing the harness. Also, Industry best practices should be demonstrated in design. All the necessary details like clearance, clipping/clamping selection, harness fixing requirements, harness continuity should be provided in order to design wiring harness.
DESIGN METHODOLOGY:
Using the geometrical parameters created,
C-1563689-1:
C-776438-4:
C-1924487-2:
Create new product file for inter connection connector and cavity assembly.
Then create a new product assembly with channel bottom and top part assembly. And Create Channel symmetrical assembly and define the symmetry bottom channel electrically using define mounting equipment option and also create all the required geometrical parameters on it.
Creating the Main Assembly:
Context assembly is nothing but the product file which contains the engine 3D-CAD data and the engine harness geometrical bundle. Here the geometrical bundle product contains all the connectors and other mounting equipments, clips and clamps which are electrically defined for the assembly. Sheet metal L-clamp are added in the main context assembly.The we need to switch into the electrical harness assembly workbench and Geometrical bundle product file should be electrically defined using the Define Geometrical bundle option before adding any parts into it.
The Given V16 engine 3D-CAD model requires a total of 23 connectors to be placed on it and an inter connection connector for the engine wiring harness assy. The connectors used in this engine are as follows
However, situation of interconnection connectors are not similar to device connectors. Interconnection connectors are not parked with any device but should be pared with the help of clips/clamps/sheet metal brackets etc. possible to the packaging conditions.Un parked connectors can create following issues-
Assume the bundle connection from the chassis is coming from right side of the engine and therefore L-clamp is provided on the right side of the engine which provide proper support for the interconnection connector. Here the cavity clip is inserted into the hole provided on the L-clamp.Additional slack should be provided to the chassis bundle connecting to the engine harness interconnection connector to protect the wiring harness from vibrations caused during the vehicle operation.From the above pictures we can clearly see that the L - Clip is mounted to one of the holes provide on the Engine block for the screw and it is rested onto the ribs so that it restricts its rotational movement during tightening of the screw.And also, we can see that the Interconnection Connector have been placed and it is Electrically connected with the cavity provided for it.The L - Clip should be added to the main product as it is not a part of the Geometric bundle or the Wire harness bundle.
Adding supporting components like p-clamps and firtree clip can help the harness bundle provide proper routing and also help to prevent the harness bundles fouling from unwanted mechanical components.
Routing the wiring harness to the connectors :
Go to electrical harness assembly workbench and select geometrical bundle command and select the geometrical bundle in the model tree. Then select the multibranchable command to start the bundle routing and go to route definition.
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>
FLATTENING HARNESS:
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.
we are creating new drawing file and defined all the necessary drawing parameters. We have to insert the front view of the Engine Harness Flattening Product file into the Drawing file.
To convert .Catpat file into product file and save as .igs FILE:
After this process it looks like as
FINAL TREE :
CONCLUSION:
In this project i have successfully routed the wiring harness for the V16 Engine assembly and the flatten-view drawing was prepared in CATIA V5. Various packaging rules and constraints were considered while routing the harness. After finalizing the wire routing, we can request the corresponding Engine design team to provide additional holes for the mounting of Fir tree clips.
