Project 1-Meshing of Rear Wheel Holder challenge

AIM :- Shell (2D) Meshing of back wheel holder with given quality and assign thickness.

Objective :-

*To perform 2D shell mesh on the back wheel holder of car by given criteria.

*To assign thickness for the component.

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

Procedure :-

1. import the model.

* first import the given model.

2. Geometry cleanup and topology:

* After importing the model we have to check the geometry and if any is error is found , clear this with cleaning tools such as quick edit tool , surface edit tools, etc.

* In this process we also check for free edges , gaps , overlaped surface and T-edges.

3. Mid surface extraction:

* For extraction of mid surface first we have to check thickness of surfaces so that we can decide whether go for manual or auto mid surface extraction.

* For thickness measurement we use distance tool. ( geom - distance )

* For the thickness of the component uniform. we use the extraction of automidsurface.( 0ffset +planes+sweeps).

*given auto midsuface is create in free edges and not proper feature.

*then we use quick edite panel in such as toggle and point to point replce as well.

* we can see the below image is overlaping and not trimed two surface together.

* then we use the surface edit panel in trim with sur/plane option join the together.

* this small feature well removed the component .and fill the hole in use the split/fillet option in surface panel.

4. meshing

* First we set the quality criteria

* we can go to tha auto mesh panel .select the surface one by one mesh the whole component.

* For fix this issue of failed elements and flow and other importan aspects we use different tools such as rebuild mesh, remesh element , quality index tools, place nodes , replace nodes , translate nodes , etc.

* In this way we pass all element for givne quality criteria.

* After solve this issue of elements failure and fow we check for free edges. ( tool - free edges )

* After this we check for normals so we ensure that all elements have in same normal.

* For checking the normal we go to tools and then normals select elements and click on display.

* In this process we found some elements are in different normal so we select these element and click on severse

5. creating propery and material.

* In this model we have to create propery as well as material.

* so mearsure the thickness of the component.(0.75)

*accourding to thickness create the materials.

* Then we create the property for these materias and give thickness value to property according to different component's thickness.

6. FINAL MODEL.

CONCLUSION:-

* In this project we learn 2D meshing of sheetmetal component and assign the thickness.
