Week - 4 - 2D meshing for Plastic components

)AIM: For the given Plastic Bottle Cap model, check for the geometrical errors and take the mid surface by suitable mid surfacing techniques. PID and Thickness assignment has to be done for all the mid surfaces. Mesh the same with given element Quality criteria.

objective: To extract manual mid-surface for the plastic component and to mesh it with given parameters

procedure.

1) import the geometry in ansa

2) set con res to 1 mm, use fine in auxiliary to refine curves.

3) use offset to offset the circular part in the geometry.

4) project necessary cons and cerate the surfaces using faces new or surface coons.

5) for creating teeth use middle multi option in faces, transform tool rotate option. in this select two-point axis. make a point using COG of the circles.

6) Use curves middle to extract threads. project curves on the surface and make faces new using coons. you will get continuous Tripple cons.

7) Use extend and intersect command for joining ribs and other portion .

8) assign quality parameters and quaality criteria. use cut option to for geeting good mesh.

conclusion: we learnt how to design solid plactic component with thickness less than 6 mm
