project 2

Aim:-For the given Rear suspension , check for the geometrical errors and meshand apply connection with the given element Quality criteria.

Procedure

1. First open the given rear suspension system in Ansa apply Topology and check the geometrical error of the given component.

2. Given suspension system is broken in to different component and set pid, check geometrical error of the inividual component, check the thickness of each component. If thickness is less than 5mm extract the mid surface for hollow an more than 5mm component choose for the solid mesh according to the given quality criteria.

Generation of two dimensional and solid mesh

First open the mesh parameter set the target length according to the given criteria then open the presentation parameters and feed the given data in mesh module select length apply perimeter and micros according to the given criteria. In mesh parameter set mixed element for two dimensional meshing and ortho tria mesh for solid meshing.

By using spotmesh , freemesh and best mesh is used for meshing the extracted mid surface and solid component. After meshing use resonstruct, remesh,paste, Move ,MV free is used to minimize the tria best quality criteria for the meshed surface. View the off element in shadow mode.

For meshing the solid component use ortho tria mesh for the curved surface and tria mesh for the flat surface. Using combination of both mesh type to reduce time in processing and good looking. To genetate tetra mesh to volume mesh move to the volume mesh module first define the volume by manual selection then go to list after right click choose remesh and Select Tetra FEM for the solid mesh.

To remove the off element from the solid mesh right click on off element select show only apply first level choose fixed quality select the entire element. After meshing of all the component apply RBC connection in the bolt area for overlaping surface apply overlap shell connection for perpendicular surface apply Y-joint shell connection.

Conclusion:-

From the above project we learn about different type component and fixed the quality according to the thickness of component and assign the pid apply 2D, 3D meshing therefore apply connection at the suitable place.
