Challenge 7 : Concept Modelling of Steering Wheel
1. title :-
design 3D model and check surface quality of steering wheel of mercedes in the alias software.
2. objective
1. to created model of steering wheel as per providing blue print.
2. evaluated of curves and surface continuity of BMW steering wheel
3. introduction
steering wheel is part of car and it controls driving direction of the car. nowaday, steering wheel are using in the morden automobile vehicles as example car, truck, bus, tractor, construction vehicles and more. steering wheel is part of steering system which locate at the passenger cabin to drive side. In the past, steering wheel include rack and pinion gears. they are providing good control on the car but steering wheel is very hard to rotate and it is many rotation need to turn on driving time. this days and age we are using hydraulic power steering and it make to easy to turn and low rotation compare to old steering wheel.
in this project, we are generate model of steering wheel and we are trying to match it with mercedes AMG steering wheel blue print. model have tried good quality of surface. further, we have writed in detail of model planning and tools information.
4. Design methodology
preparation plan of steering wheel for generating model
1. find out a same pattern on the blue print ( there is same pattern in the steering image )
2. steering wheel are dividing three part- handl rod, button part, central horn button.
3. steering wheel divid two sections and only one is draw and second section is create by mirror command
4. model is starting to draw from the outer to inner side or bottom to top side
5. use curve tools and surface tools for making surface.
step for generate model
1. set a image on the software.
2. divide a blue print as per same pattern (there is divid image of steering wheel )
3. starte making from the bottom side to top side of fender with the help of curve tools.
4. generate surface on the curve network
5. check surface quality
5. Description
- Input image
File – import – canvas image – open browser and select photo
Another way is you can select image and hold right mouse button and move in the software screen (automatic image input in your need side).
- Curve tools
Window – palette – curves tool – (line, blend, curve and many tools are their)
This tools use for network generation.
- Surface tools
Window – palette – surface tool- (sphere, planar, skin, rail, square, multiple curve ).
Above tools are use for surface generation. Skin tools is create two side surface. Rail tools is crate two, three and four side surface. Square tools use for four side surface. And multiple curve tool use for more then 4 side surface.
- joining of two curve
pick the curve - move – press ctrl + right button mouse or ctrl + alt + mouse middle button
- Short key for pick, move, scale
Shift + ctrl + right button mouse
Shift + ctrl + middle button mouse
Shift + ctrl + left button mouse
- Zoom in and zoom out
Shift + alt + mouse right button
Middle button move round
- Project, trim tool
In the Palette - surface edit - project (any curve project on the surface)
In the Palette - surface edit – trim tools ( any portion cut by this tool)
- Check surface quality
For quality of surface, Skin control bar, rail control bar and square control bar open and find check surface quality and also G0, G1, G2, G3 option through change quality of surface. Crvcvtr tool use for curve smoothness.
9.mirror and dublicet
edit - dublicate- select (mirror or object )
mirror is use for the copy of pattern and paste on the other side.
object use for mode is copy and rotation paste.
10. surface filet
this tool is making round and champer edge of the surface
palette - surface - filet
6. Model image
isometric view
front view
side view
top view
7. Conclusion
to conclude that the model create in the alias software and Mercedes AMG steering wheel use for the generate a model of steering wheel. model has a good quality of surface as well as we wrote a making point, panning and tools information.
