Week 4- Challenge

Objective: To Mesh the Given component with the Size of 5mm and Create 1D elements on the component with given cross-section and DOF

Procedure:

• import the model
• create a new component and name it to bracket 2, this is done to transfer the mid surface of bracket 2 to this component (to prevent the mid surfaces of the components from combining )
• create the mid surface of both the upper and lower bracket and delete the solid parts

• now transfer component 2 to the previously created bracket 2 by going to tools---> organize --->select current component as bracket 2--->move
• now create material steel since we need to assign some thickness to the components
• create 2 property (one for each component)
• assign the material and thickness to the property

• assign the property and material to the component

• now mesh the component

• create three hyper beam models BOX, I, and X

• create 3 properties for the three cross-sections required and assign them to the models created in hyperbeam

• after meshing as per the question create a rod element and constrain translational DOF with RBE2 link

  with (a) Cross-Section: BOX- Dimension a= 12 mm

  dimension b=10 mm

  Thickness t= 0.75 mm

  

• Beam element:- All DOF constrained with RBE3 link

  (b) Cross-Section: I Section- Dimension a= 8 mm

  Dimension b= 10 mm

  Dimension c= 8.5 mm

  Thickness t1= 0.75 mm

  Thickness t2= .6 mm

  Thickness t3= .6 mm

• 

• 

• Bar element:- Constrain only x and y DOFs With RBE3 link

  (c) Cross-section: X section- Dimension DIM1= 5 mm

  Thickness DIM2= 1.2 mm

  Dimension DIM3= 10 mm

  Thickness DIM4= 1.2mm

• 

• 

• for places (d) and (f) we create RBE2 link and apply a mass of magnitude 10 to the master node

• 

• 

• for part (f) we join the components with spring elements

• 

• final model
