Applications of computers:
- Geometric modelling,
- Engineering analysis,
- Design review and evolution,
- Drafting.
(a)Geometric modelling:
Hear CAD
package is used, which takes input from the designer as a mathematical
expressions and it represents as a graphics on the interactive Computer
Graphics (display).
A CAD package
should capable to representing the given input as a picture on the screen.
Various
packages represents the given command in different views such as wire framing
representation, surface representation and volume representation.
Based on the
application which method is required can be selected.,
Example: for mass property calculations- volume representation
can be used and for area calculations-
surface representation can be used.
There aare
continuous interaction between ICG and input devices through programmer and
designer interaction.
(b) Engineering analysis:
Engineering
analysis is made in two methods. mass property calculations and finite element
methods
Mass
property calculations: volume represented components can be used to find
volume, density and cost associated with the component.
Where is
finite element analysis is used to divide a component into finnet atoms into
finite elements. The solution to each element is found and overall behaviour of
component is determined using Global mattresses.
(c) Design review and evolution:
Once
engineering analysis is done, the evolution of the component plays very
important role to find out any error.
So many
methods are available to review the components such as zoom in and zoom out,
layering technique, colouring technique.
(d) Drafting:
Here hard
copy of the component with different views such as orthogonal, isometric,
oblique, 3D, 2D etc., using printers, drafters.
