Component - Model

Procedure:

At first, we will import the geometry model into Hyper mesh as shown in the image below.

Then we will mesh the whole geometry with the given target element size and quality criteria as discussed in the objective. The meshed model qualifying the criteria is shown in the image below.

The first connection is between Right_Rail_2 & Front_truss_1 with the type of connection to be Seam-Quad (Angled+Capped+L) as shown in the image below.

The second connection is between Left_Rail_2 & Front_truss_1 with the type of connection to be Quad elements as shown in the image below.

The third connection is between Front_truss_2, Front_truss_1 & Right_Rail_1 with the type of connection to be Spot weld with 3 Layers and 5 mm Diameter as shown in the image below.

The fourth connection is between Front_truss_2, Front_truss_1 & Left_Rail_1 with the type of connection to be Hexa (Adhesive) as shown in the images below.

The fifth connection is between Rear_truss_2 & Right_Rail_2 with the type of connection to be Bolt Connector as shown in the image below.

The sixth connection is between Rear_truss_2 & Left_Rail_2 with the type of connection to be Bolt Connector as shown in the image below.

The seventh connection is between Right_Rail_1 & Right_Rail_2 with the type of connection to be Spot-weld with Rigid Elements as shown in the image below.

The eighth connection is between Left_Rail_1 & Left_Rail_2 with the type of connection to be Spot-weld with Spring Elements as shown in the image below.

Hence, we have provided the mesh and the connections as discussed.
