Week 4- Challenge

Aim: To Create 1D elements on the following component with given cross-section and DOF

Objectives:

1. Creating RBe 2 and RBe 3 links.
2. Creating rod element, beam element, bar element and spring elements to join the 2 components.

Procedure:

1. Import the given model- File > Import > Geometry.

2. Extracting the mid surfaces:

• Extracting the mid surface for bracket 1-

• Similarly Extracting the middle surface for bracket 2 and delete the solids.

3. Meshing the model:

• Before meshing the model create the washer splits to the present holes-

Quick edit > washer split.

• Create 2d shell mesh- 2D > auto mesh > create.

4. Creating links:

• RBe2 at ‘a’- 1D > Rigids > elem type= RBe2, dof1, dof2, dof3 > create.

• RBe2 at ‘d’ and e - 1D > Rigids > elem type= RBe2 > create.

Springs at ‘d’ and ‘e’- 1D > springs > create.

Masses at ‘d’ and ‘e’- 1D > masses > create.

• RBe3 at ‘b’ and ‘c’-1D > RBe3 > create.

5. Creating Rod, Bar, and Beam elements:

• Rod element at ‘a’ – 1D > Hyperbeam > standard section > solid rectangle.

Dimension a=12mm, dimension b=10 mm, Thickness t= 0.75 mm

• Beam element at ‘b’ – 1D > Hyperbeam > standard I- section > create.

I Section- Dimension a= 8 mm, Dimension b= 10 mm, Dimension c= 8.5 mm, Thickness t1= 0.75 mm, Thickness t2= 0.6 mm, Thickness t3= 0.6 mm

• Bar element at ‘c’ – 1D > Hyperbeam > Solid circle > create.

Dimension DIM1= 5 mm, Thickness DIM2= 1.2 mm.

6. Assigning material: for Bracket 1, Bracket 2, Bar, Beam and Rod.

Create > material > steel.

7. Assigning property: update properties for rod, bar and beam elements after creating properties.

RESULT: Created 1D elements on the following component with given cross-section and DOF.
