ASSIGNMENT-2 RADIOSS ENGINE FILE EDITING AND 3D MESHING

CALCULATION:

Check the material properties of the rail component and calculate the speed of sound in steel rail = 5188.74mm/ms

E = 210000

Density = 0.0078

C =5188.74mm/ms

The length of the rail is about 1000mm. Calculate the time takes for a shock wave to travel from one end of the rail to the other.

Time for sound to travel the length of the rail= 0.192ms

length=L=1000

Speed of the sound = C= 5188.74mm/ms

DT= L/C

= 1000/5188.74 = 0.192ms

The length of the rail is about 1000mm. calculate the time takes for a shock wave to travel from one end of the rail to the other.

MODEL 1:

Import the engine file
go to view - browser - hypermesg - solver - run - engine run and change the time stop 60.
set the frequency of animaion output at a given 20 animation step.
Tfreq= 60/20
change in Tfreq=40
go to engine keyboard-Animation-animation/DT-Eng Animation/DT
Set Tfreq 40
change/print-10
3D meshing hex mesh 10
taken the base part, hide the remaining parts and mesh the component
go to 2D mesh, select automesh where element size is 10.
Go to the component select the arm curve, make it as current component.
press F4-3 nodes- select the curve- create a node at center of curve
In order to mesh the curve go to 3D Page - spin select the element - center node - dreg line - select angle , keep element size 10..
go to tool page - face - select the arm curve component - assign tolerance value - find face.
In order to mesh arm straight , mesh the front face of it with same no of element placed in arm curve .
go to 3D pages- solid map- source element- destination element - same 3 nodes for the faces of direction N1,N2,N3.
Like previous step we have generate face for arm structure in next steps.
In order to mesh the boss we have create some nodes in boss component.
go to 3D page -solid map-deselect source geom-dest geom-select mixed in along geom-element drag, make sure that element size 10
go to shift+f11 - select the solid map component - move to boss component.

MODEL 2:

AIM:

PROCEDURE:

First import the model in hyperworks and after importing the model ,mesh the surface .
now create 1D element between the 2 meshed surfaces to perform this operation go to the main menu and select 1D.
In 1D element first select rods and element type TRUSS 2N. select 2 opposite nodes anywhere on the shel element and this will create a 1D element between them.
Similarly create one or more element i.e, a bar / beam element . this time 1D ,select bars and element type as BEAM3N.
Now create properties for these element by going to the tool bar.
For TRUSS2N element select card image as P2_TRUSS and hyperbeam selection select section type as HMCIRCLE and give any suitable thickness to it.
similarly for BEAM 3N element select card image as P3_BEAM and in hyperbeam section select selection type as HMBOX and give any suitable thickness to it
once all the properties are created assign them to their respective components.
After all the components are assigned with their respective properties , go to tool bar > select from list > 1D detailed element represtation .
save the model in HM format.

RESULT:

1D element were successfully created and the properties have also been assigned to the respective components.

MODEL-3

3D meshing tetra mesh
open the next component , to check view 3D topology go to 2D page-auto mesh-select surface-element size as 5- mesh types as trias -click mesh.
next move to 3D page-tetra mesh - select the component- move tetra parameter - select the min tetra size 5- again move to tetra mesh- mesh the selected component.

go to F5 mask option -after tetra mesh we have check wheather it done properly, after unmask the element .
check the quality of the element press F10,3D-to check tet collapse- these component is meshed with zero error.
same procedure hub component
go to 2D pages-auto mesh - select surface-element size as 5- mesh type as trias -click mesh.
next move to 3D page-tetra mesh - select the component- move tetra parameter-select the min tetra size 5-again move to tetra mesh- mesh the selected component.
check the quality of element press F10,3D - to check tet collapse-27 element are failed- saved the failed element.
move mask-element-reterive - mask- reverse failed element are visible.
go to shift+F2- nodes- displaced -odd nodes, it will help to identified the failed element.
select the element and remesh it.
go to mask-unmask the element, the component is meshed completed with zero element failure.
here the finall part of housing is done.
