1D Connections for the given model using Hypermesh

AIM: To Create connectors for the given model as mentioned above.

KEYWORDS: Bolt, Spot, Seam, Spring, Hexa, Rigid, etc.,

SOFTWARE: Hyperworks

OBJECTIVE:

Checking for the geometry cleanup is a primary thing that helps to define the geometry completely.

After the geometry cleanup, quad meshing is performed based on the study.

Create the connectors for each component as mentioned above and study the different types of connectors listed.

INTRODUCTION:

1D Elements are simple connections between nodes. Standard 1D Elements are,

RBE2 Rigid link to transfer motion from the independent node to the dependant node(s).

RBE3 Rigid link to distribute loads. Will not induce stiffness.

Beam/Bar Non-Rigid Link that has properties that include cross-section and material definitions.

Purpose of Connectors:

Geometric entities that define connections between other entities

• Used for welding, bolts, adhesives, etc.
• Link geometry or FE entities
• Can be “realized” into FE representations of welds, etc. for any supported solver
• rigid, CWELDs, MAT100s, ACMs, etc.
• Connectors allow for easy and rapid:
• Creation of FE welds, bolts, adhesives, etc.
• interactively or from:
• XML file
• MCF (master connectors file)
• Spot welds only
• Switching between different FE configurations of welds, bolts, adhesives, etc.
• Part swapping and reconnection
• Replacement by names or IDs

RESULTS:

1. Right_Rail_2 & Front_truss_1:- Seam-Quad(angled+capped+L)

2. Left_Rail_2 & Front_truss_1:- Quad elements

3. Front_truss_2, Front_truss_1 & Right_Rail_1:- Spot weld with 3 Layers and 5 mm Diameter

4. Front_truss_2, Front_truss_1 & Left_Rail_1:- Hexa (Adhesive)

5. Rear_truss_2 & Right_Rail_2:- Bolt Connector

6. Rear_truss_2 & Left_Rail_2:- Bolt Connector

7. Right_Rail_1 & Right_Rail_2:- Spot-weld with Rigid Elements

8. Left_Rail_1 & Left_Rail_2:- Spot-weld with Spring Elements

9. Front truss 1, Reinf_plate & Front truss 2: Spot weld with 2 layer

10. Left Rail 1 & Rear Truss 2: Hexa (Adhesive)

11. Rear Truss 1 & Rear Truss 2: ACM(Shell gap + Coating)

12. Complete Assembly with connectors:
