Project - 2 - Meshing on the suspension Assembly

AAnkit Panchal13 Sept 2022

ANSA

Aim : To visualize mesh for the given component car suspension system using ANSA.

APPARATUS :- FE MODEL,LAPTOP,ANSA SOFTWARE.

Procedure :

Check the geomentical errors in CHECKS MANAGER and fix them manually.
Try to measure the thickness and set PID for those regions.so,that meshing can be done based up on the PID setup.
If the thickness is less than 5mm and uniform take mis surfa ce and mesh for those region.

Step 1:- I check for the geometrical error. and clean the geometry 100%. for given Model.

Step 2:- THEN I WILL DESTROY THE GEOMETRY IN DIFRENT PARTS AND PROPARTY.

Step 3 :- Make Mid Surface one by one for total geometry And

Make Mid Surface Meshing with given element Quality criteria.

Quality Criteria:

S.No	Quality Criteria	Value
1	Target/Average length	4
2	Minimum Length	2
3	Maximum Length	6
4	Aspect	3
5	Warpage	15
6	Skewness	45
7	Jacobian	0.7
8	Minimum Quad Angle	45
9	Maximum Quad Angle	135
10	Minimum Tria Angle	30
11	Maximum Tria Angle	120
10	Tria Percentage	20

PART 1:-

Washer Element :-

PART 2:-

PART 3:-

TO VIEW THE SHELL SOILD PRESS F11 >GO TO THE PRENSENTATION OF PARAMETR>CHECK THE DRAW SHELL SOILD.

Step 3 :-

Make 2D Mesh / Shell Mash.

In Some Curved Area I Use Ortho Tria Elements For good Meshing Results.

Make 3D Mesh / Solid Mesh.

In Volume Mesh / Solid Mesh .

Quality criteria for Surface Meshing of Non Uniform thickness components other than Tyre and Rim (Element type: Tria) :

S.No	Quality Criteria	Value
1	Target/Average length	4
2	Minimum Length	2
3	Maximum Length	6
4	Skewness	45

Quality Criteria for Volume meshing of all Non Uniform thickness components (Element type: Tetra Elements):

S.No	Quality Criteria	Value
1	Tet-collapse	0.2

1]Define:- Define the volumes for the shell elements using volume mesh-volumes-define-Wholedb. Select the component one by one using PID tool.

2]List :- After creating property for individual component. Now we can mesh the shell elements to solid elements using v.mesh-volumes-list. Now Rightclick the defined component in list tool. After that select the remesh option. Now the mesh tool module appeared, select the method you want such as tetra rapid or tetra FEM. (In this project Both Tetra Fem is done)

3]Move :- Move Free, If any 3D elements are failed for tet collapse. Use fix quality tool v.mesh-improve-fix quality. we can use another tool such as mvfree by selecting grids-mv free.
