Week 9-Challenge

HyperMesh for FEA Plastic and Sheet Metal Applications

OBJECTIVE:

For this week\'s challenge, you will have to make use of connectors to attach various parts of the model

Question

Create connector and Attach the various parts of the given model

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 weldwith 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 withSpring Elements
9. Rest all the component left Join them with suitable connectors

PROCEDURE:

• Open frame_assembly_welding.hm file in hypermesh.
• Mesh entire component by using 2D automesh. I have kept quad element of 6 mm size.
• Use steel as material and 2 mm thick property.

Below connectors are created:

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

• For seam-quad connector use 2D > connectors > seam > select node path for seam weld > spacing = 5 > comp > type Seam-Quad(angled+capped+L) >. Imprint > create
• Re-mesh the distorted mesh.
• Below is image for Seam-Quad(angled+capped+L)

1. Left_Rail_2 & Front_truss_1:- Quad elements

• For quad element connector use 2D > connectors > seam > select node path for seam weld > spacing = 5 > comp > type Quads > Imprint > create
• Re-mesh the distorted mesh.
• Below is image for quads elements connector.

1. Front_truss_2, Front_truss_1 & Right_Rail_1:- Spot weldwith 3 Layers and 5 mm Diameter

• For spot weld connector use 1D > connectors > spot > select node path for spot weld > select comp > layer 3 > type weld > dia 5 mm > create
• Similar process use to other side.
• Below is image for spot weld connector.

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

• For adhesive connector use 2D > connectors > Area > select element for adhesive > comp > type adhesives >.
• Re-mesh the distorted mesh.
• Below is image for adhesive connector.

1. Rear_truss_2 & Right_Rail_2:- Bolt Connector

• For bolt connector use 2D > connectors > Bolt > select nodes for bolt > comp > type (bolt general) > select create hole if, none > create.
• Re-mesh the distorted mesh.
• Below is image for bolt connector.

1. Rear_truss_2 & Left_Rail_2:- Bolt Connector

• For bolt connector use 2D > connectors > Bolt > select nodes for bolt > comp > type (bolt general) > select create hole if, none > create.
• Re-mesh the distorted mesh.
• Below is image for bolt connector.

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

• For spot weld connector use 1D > connectors > spot > select node path for spot weld > select comp > layer 2 > type rigid > dia 5 mm > create
• Similar process follow for other side also.
• Below is image for spot weld connector.

1. Left_Rail_1 & Left_Rail_2:- Spot-weld withSpring Elements

• For spot weld connector use 1D > connectors > spot > select node path for spot weld > select comp > layer 2 > type spring> dia 5 mm > create
• Similar process follows for other side also.
• Below is image for spot weld connector.

Remaining Component:

1. Reinf_Plate , Front_Truss_1 & Front_Truss_2 : Spot-weld with Rigid Elements

• For spot weld connector use 1D > connectors > spot > select node path for spot weld > select comp > layer 2 > type rigid > dia 5 mm > create
• Similar process follow for other side also.
• Below is image for spot weld connector.

1. Left_Rail_2 & Front_truss_2:- Quad elements

• For quad element connector use 2D > connectors > seam > select node path for seam weld > spacing = 5 > comp > type Quads > Imprint > create
• Re-mesh the distorted mesh.
• Below is image for quads elements connector.

1. Right_Rail_2 & Front_truss_2:- Spot-weld with Rigid Elements

• For spot weld connector use 1D > connectors > spot > select node path for spot weld > select comp > layer 2 > type rigid > dia 5 mm > create
• Similar process follow for other side also.
• Below is image for spot weld connector.

1. Left_Rail_1 & Rear_Truss_2 Hexa (Adhesive)

• For adhesive connector use 2D > connectors > Area > select element for adhesive > comp > type adhesives >.
• Re-mesh the distorted mesh.
• Below is image for adhesive connector.

1. Right_Rail_1 & Rear_Truss_2 Hexa (Adhesive)

• For adhesive connector use 2D > connectors > Area > select element for adhesive > comp > type adhesives >.
• Re-mesh the distorted mesh.
• Below is image for adhesive connector.

1. Rear_Truss _1 & Rear_Truss_2 Spot-weld with Rigid Elements

• For spot weld connector use 1D > connectors > spot > select node path for spot weld > select comp > layer 2 > type rigid > dia 5 mm > create
• Similar process follow for other side also.
• Below is image for spot weld connector.
