Week 12:Project 2-Meshing of Rear Wheel Holder challenge

AIM: To mesh the Rear wheel holder.

OBJECTIVE: To mesh the given component with the given quality criteria.

Target Element Length = 5 Units

S.N	Quality Criteria	Value
1	Aspect Ratio	5
2	Skewness	45
3	Warping	15
4	Taper	0.5
5	Min. Length	2 Units
6	Max. Length	8 Units
7	Min angle Quad	45
8	Max angle Quad	135
9	Min angle Tria	20
10	Max angle Tria	120
10	Tria %	10

COMPONENT:

PROCEDURE:

• Import the geometry into hypermesh.
• Check the thickness and extract the midsurface by using suitable extraction option. To extract mid surface go to geom>midsurface>auto midsurface>extraction option (select offset+planes)>auto exctraction>select the surface >extract.

Extracted midsurface:

 Delete the suface and recreate it using Quick edit panel>unsplit, filler or using the Surface>Ruled option

• Now, clean up the geometry By using Toogle or edge replace option To avoid sharp edges where elemets fail for minimum lenght.

• Set the Quality criteria and parameter file setting before meshing. 
• For criteria file setting go to the preference> criteria file setting 

• For parameter file setting go to preference> parameter file setting.

• Then, start meshing manually, i.e, surface by surface to achive the proper mesh flow 

Meshed component:

 

• After meshing check for the free edges Goto tool>edges>elements>select all the elements >find edges.

• Assign the properties i.e, the Thickness of the material 0.75

FINAL MODEL 

CONCLUSION:

The Given component is meshed with given criteria and parameter file setting.
