Project - 2 - Meshing on the suspension Assembly

                                                                     Meshing on the suspension Assembly

Aim:-

Mesh the given rear suspension accordingly with 2D & Volume meshing as per the given quality criteria. Connections to be deployed for the model. Replicate the model symmetrically after all the meshing and connections.

Steps Followed:-

• Geometry Clean-up.
• Mid surface extraction & 2D meshing.
• Volume Meshing.
• Bolt & Seam Weld Connection.
• Symmetrical Replication.

Quality Criteria:-

Surface Meshing of Tyre and Rim (Element type: Tria) : 

S.No	Quality Criteria	Value
1	Target/Average length	6.5
2	Minimum Length	5
3	Maximum Length	10
4	Skewness	45

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

Volume meshing of all Non-Uniform thickness components (Element type: Tetra Elements): 

S.No	Quality Criteria	Value
1	Tet-collapse	0.2

Mid surfacing of Uniform thickness part which has a thickness less than 5 mm (Element type: Mixed elements) :

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

procedure:-

Import the given model to ANSA. Clean up the model and check for geometrical errors.

 with peoper geomentry and quality criteria.

following step to be done for meshing the given Rim and Tyre Model.

FACES < TOPO 

And to use UTILITIES < GEOMETRY CHECK < OK 

After cleaning the geometry .

create the 2d shell mesh and create ortho tria and tria.

ortho tria for better mesh in edge area.

tria and ortho tria can be created in spot mesh for rims and tyre.

And create the 3d tetra mesh for tyre and rim.

 VOLUME option create for tetra rapid mesh.

other parts can be created the 2d shell mesh and created the tria mesh.

 VOLUME option create for tetra rapid mesh.

1d spring

CURVE option and create MIDDLE for get middle curve.

NASTRON deck < CBAR 

after cteating all parts to2d mesh and 3d mesh 

connectin option can created and connect all parts

UTILITIES < TRANSFORM < COPY

SECTION WINDOW < ENTITIES 

COPY  ENTITIES < SYMMERTY < MIRROR 3 POINTS PALNE.

learning Outcome

• Manage 2D and Solid meshing together with different quality criterias.
• 1D CBAR element for Spring.
• Symmetrical replication of components.
• Concept of suspension assembly meshing.

Result

The given Suspension assembly is meshed using 2D and tetra mesh with the prescribed quality criteria. Connections are deployed as required. The other half of the assembly is reflected symmetrically.
