AIM
To create the assembly wiring harness as per the image given below
Step 1:- We must first define all the connectors geometrically and electrically as shown in
the image below
First, we will locate all the connectors at their desired position, add branch points required
and create bundle segment according to the diameter assumed as 15 mm and 10mm
Harness A :
Harness B:
Step 3:
. Now in this step, we must check bundle continuity in both Harness A and Harness B.
. So, for that , go in Edit>Search>Workbench-Electrical>Type-Bundle segment>Attribute-fully
connected.
. We will get one window, in that selecting True option will show all the connected bundle
segments while selecting False option will show all the non-connected bundle segments.
. Now, we will check for True condition and search for result.
. All the bundle segments are shown connected. So, there is bundle continuity in both Harness
A & Harness B as shown in below image.
Harness A:
Harness B:
Step 4:
. In the step, we must interconnect both Harness A & Harness B.
. For that, we must create a new product file and can give the name as assembly.
. Then, copy both harness and paste it in newly create product file or call both harness
in mechanical assembly design as below image.
. We must go in Electrical Assembly Design to connect both the harnesses electrically. So, for
that, select the option 'connect electrical devices' and both the harnesses will get
connected electrically as below.
Step 5:
. In the step, we will be checking the bundle warning in the Harness A & B.
. Geometrical bundle warning are shown for bend radius, bundle diameter and vector position
. So, if there is any incorrect value or input regarding these factors then yellow colored flash
will be appear in the model tree structure next to the branchable with problems.
. This error can be corrected by adjusting the location of the connector.
Step 6:
. In the step, we must add annotations for all the connectors in mechanical assembly
design workbench.
. Annotations are used for giving connector names, functions etc.
. For this, we must select a plane where annotation will be placed. In the image below, we have
selected the front plane.
. So, after giving annotations to all connectors, the whole assembly will look as below.
Step 7:
. Now, in this step we must convert the final harness assembly file into IGS format. So, for that
we need to follow the steps below.
. Mechanical Assembly Design workbench>Tools>Generate CATpart from product.
. Once the CATpart is create, the whole product file is converted into a singal part.
. Now, the whole file is converted into the IGS format, and we can see all the harness assembly
is looking in grey color.
. If we need to change color as before in green, we can go back and give green color to each
bundle segments.
Note:
Overall Assembly is named as Assy Wiring Harness.
