Project

Creating 1D elements on the following component with given cross-section and DOF for every section

OBJECTIVE :

Creating 1D elements on the following component with given cross-section and DOF for every section.

a. Rod element:- with only translational DOF and RBE2 link

Cross-Section: BOX- Dimension a= 12 mm

dimension b=10 mm

Thickness t= 0.75 mm

b. Beam element:- with all DOF and RBE3 link

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

c. Bar element:- with only x and y DOFs With RBE3 link

Cross-section: CROSS section- Dimension DIM1= 5 mm

Thickness DIM2= 1.2 mm

Dimension DIM3= 10 mm

Thickness DIM4= 1.2mm

d. & e. apply the mass of magnitude 10 with RBE2 link

f. Join the two components with Spring elements

PROCESS :

FIG.1 SHOW THE PID MODE OF THE TWO BRACKETS WITH ALL THE GEOMETRY ERROR ELIMINATED AND CREATED WASHER

Clear all the topo error by auto-clear command or we can go by manual mode
it clears the geometry errors and creates the washer surface around the circles so that the mesh should be fine
Create a washer surface to the circles present on the mid surface to do meshing.
We have to change the component colour for representation.
Next step to do 2d shell meshing over the surface and eliminate the tria elements.
with given target element size.
take care that there should not be any opposite trias, trias near-circular surface & trias on fillets.

FIG.2 MESHIG DONE OVER THE SURFACE AND RBE2 AND RBE3 ELEMENTS ARE CREATED

As there \'a\' point is mentioned we have to allot RBE2 elements with only a translation degree of freedom.
And if their \'b\' point is mentioned we have to provide RBE3 link with all degree of freedom.
therefore \'c\' point is mentioned we have to provide RBE3 link with only x and y degree of freedom.
we have done it by going to the 1D page and selecting the option of Rigid and RB3 respectively

FIG.3 1d elements cration in hyper beam mode

We have created a ROD, BAR, and BEAM we have to go to the hyper-beam option directly.
Inside the hyper-beam window, we select the cross-sectional area as given in the objective:
- Rod = Box section
- Beam = I section
- Bar = Cross-section

FIG. ROD BAR BEAM MASS AND SPRONG REPRSNTAION WITHOUT THICKNESS IN COMP MODE

Connect both brackets with a rod, bar, beam, and spring 1D elements.
And this is not been seen as the rod bar beam we need to change the view to 1D detail representation we can see the actual thickness given to the 1 d elements for that we need to assign material like steel and properties to be updated and assign the properties to them.
