Week 4-1D Element Creation Challenge

Objective:

To Mesh the Given component with the Size of 5 Units,Create 1D elements on the following component with given cross-section and DOF by using Hyper Works.

Softwaer Used:

Hyper Works 2021

Given Component:

Procedure:

• Import the model file using following steps Import model→Import geometry
• First create mid surface for the model using following steps Geom→midsurface
• Delete the all solid parts then the mid surfaces oly remain
• Then asign properties for the brackets on Tab bar
• We need to give washer split for holes brfore mesh Geom→quick edit→washer split
• Then give material(steel) for entire component on Tab bar
• Mesh the given component with the size of 5 units by using following steps 2D→auto mesh

a.ROD ELEMENT

• Before create rod element create RBE2 link with Translational DOF should be Constrained
• The rod is created by following steps 1D→rods
• We need to use given dimensions for rod so we go need to create Box section by using hypear beam option 1D→Hyper Beam There we select the section which we need
• Come back to model and update the rod by following steps 1D→rod→update

now the properties and dimensions added

b.BEAM ELEMENT

• Before create beam element create RBE3 link with All DOF should be constrained
• RBE3 is created by using following steps 1D→RBE3
• Then the beam is created by using following steps 1D→bars (select CBEAM in element type)
• We need to use given dimensions for rod so we go need to create I section by using hypear beam option 1D→Hyper Beam There we select the section which we need
• Come back to model and update the rod by following steps 1D→beam→update now the properties and dimensions added

c.BAR ELEMENT

• Before create bar create RBE3 link with Constrain only x and y DOFs
• RBE3 is created by using following steps 1D→RBE3
• Then the bar is created by using following steps 1D→bars (select CBAR in element type)
• We need to use given dimensions for rod so we go need to create x section(cross) by using hypear beam option 1D→Hyper Beam There we select the section which we need

• Come back to model and update the rod by following steps 1D→bar→update now the properties and dimensions added

d&e ADDING MASS

• RBE2 is created by using following steps 1D→Rigids
• Then the mass is added on center point of the RBE2 using following steps 1D→masses

f.SPRING ELEMENT

• using following steps

1D→springs

FINAL MODEL

RESULT

The 1D element created succesfully using cross section and DOF.
