Week - 8 - Morphing
AIM:- To perform morphing on the given models .
Application of morphing in various industries:-
Morphing can be used to modify existing designs, link with optimization, or create new concepts for future studies. The application of morphing can be found for all disciplines: Crash, NVH, Durability, CFD, etc. Morphing parameters can also be used to in the optimization task as a design variable. This facilitates:
- Shape Optimization
- Topology Optimization
- Gauge Optimization
- Spot – weld Optimization
- Composite Optimization
Morphing technique used in auto industry to change the shape of the existing auto model to a new modified one.
An example of change in shape of the automotive body using morphing technique.
Morphing used in aviation industry to increase the aerodynamic efficiency of the plane. It is necessary for the aviation industry to have good aerodynamic body because this will have a direct effect on fuel consumption and performance requirements. So, morphing is the used to reshape the body .
Morphing can also be used to change the fillets, patterns on component.
CAD Models:-
Procedure:-
Starting with model 1 ,topo is performed on the model to stitch the surfaces.To begin with morphing the vents and the relative adjacent surface is isolated using and not command.
Now, the height of the vents need to be redesigned. So to do this, click on morph decknewortho. Select the surfaces of the vent and middle click.This will create grid points and box morph around the vents
Right click inside the morph box to activate the local cordinate axis.
Now, to change the height of the vents using the grid points, under box morphing panel click on move option. Select the grid points that need to be moved and check the only direction of movement (x,y,z).
The vents are succesfully morphed to a different height.
Similarly the other surfaces where morphed using the same technique.
Model 2:-
To increase the height of the dog houses and the ribs.
Isolate the dog houses and the ribs one by one and by using newortho from morph deck, create morph box,move the grids of the box using box morphing move.
Ribs height changed using min volume.
Final model 2 :-
Learning Outcome:-
From this assignment, learned how to use morph deck. How to change the shape of the surfaces, components mounted on the model.
Conclusion:-
From this assignment, we can conclude that, morphing is a method that need to be done with a very careful attention to the movement of the surfaces. Proper selection of grid points must be made to make necessary changes to the surface.
