HyperMesh - Create different types of 1D elements in the given model
Objective
Create 1D elements on the following component with given cross-section and DOF
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
Procedure :
1. Import the IGES Geometry and model to the Hyperworks.
2. Extract the midsurface with option from the Geom tab and remove the surfaces of the bracket.
3. Create Washer split before 2D automesh.
4. Using automesh from 2D tab mesh the midsurface extracted.
5. Create Properties and Material.
6. Create RBE2 (through rigid tab) and RBE3 property for all the specified a-e as required along with deselecting of dof as mentioned in objective. Further connect both points RBE2 of a (For Rod), d&e(For Spring & mass of magnitude 10), RBE3 (For Beam & Bar).
Where
dof 1 - Translational x ; dof 4 - Rotational x
dof 2 - Translational y ; dof 5 - Rotational y
dof 3 - Translational z ; dof 6 - Rotational z
7. Using the Hyperbeam option create the cross-sections for Beam.
Further Create Bar and Rod as below.
8. Change the dimension as required in the objective.
9. Edit the Card image, Material, Thickness for the Bracket 1 and 2, Further Edit the Card Image and Beam section for ROD BAR and BEAM.
Update the property type in Bar, Beam and Rod option.
10. Using the tab mentioned vied the 1D AND 2D detailed element repewsentation of the elments created.
Result:
We have created 1D elements on the given model using the dimensions and properties of ROD, BAR and BEAM.
Conclusion:
We have understood about how to allot 1D elemnts in terms of ROD, BAR, BEAM, mass magnitude and Spring. Also we have learnt use of Huperbeam and its funtions.
