Project 1-Meshing of Rear Wheel Holder challenge

AIM :

To extract the Midsurface and Mesh the given Rear Wheel Holder component by following the specified quality criteria and assigning thickness .

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

Objectives:

• To clean the geometrical error in the model.
• To extract a mid-surface of the given component.
• To take the mid surfaces of given component
• Entering the quality parameter.
• Meshing the component with minimum number of trais and good mesh flow.
• Clearing all the quality parameter which failing for quality criteria
• Assign thickness of the given component.

Procedure:

1. Open the cad file and then fix the geometrical error like unproper surface ,triple cons,distorted surface.
2. By using tools like

Visualization options

Geom-> 1) split surf-node

2) toogle edge

3)washer split

4)replace point

5)add or remove point.

6)filler surface & surface

After cleaning the all the error we have to move forward for the mid surface.

2)Mid-surfaces:

• To take the midsurfaces we have goto create property then

geom-> mid surface-> offset+planes+sweeps

By using this options still we are not getting the good midsurface so we have to manually fix it by using the tools like surfaces & filler surfaces & toogle edge.

• For the manual offset

Steps For manual offset

• Create the property first
• Then make property as current property.
• Transpercy ctrl+t
• Press Shift +F9 -> offset ->select the component-> then duplicate ->current component-> offset value->vector normal->reverse normal ->offset.

Quality parameter:

Meshing the component:

To meshing the component we have to start from the middle part to outside part to element the trais.

Tools used:

1)2D->Automesh

2)2D->Rebuild

3)Mask &Unmask

4)Quality index

CONCLUSION :

• Extracted the mid-surface of the given component
• Meshing the model by the various tools and assigning the thickness of the model
