Week 8 - Challenge 4 - Bumper
TO DESIGN A CAR BUMPER BY USING CLASS A SURFACE
AIM:
- To design a car bumper Plastic component through the given Class-A surface by creating a tooling axis and draft analysis of the given surface.
DESIGN PROCEDURE:
- To setup the class-A surface and to creating a tooling axis
- add draft angle
- To create a base surface of model
- To create a B-surface
- To create a C-surface
- To use close surface for creating a solid part model
CLASS-A SURFACE:
TOOLING AXIS:
- Tooling axis can be classified into two methods
- direct method
- For this model, to use a line at mid-point of the base of the coin holder
- Due to perpendicular walls of the class A surface
DRAFT ANALYSIS:
- The Drafting analysis was performed on the class-A surface by using the Feature Draft Analysis command.
- Using this command, the compass was set on the main tooling axis and the Draft angle was changed to 3 degrees.
CREATING CLASS-B SURFACE:
- To offset the class-A surface along 3mm for to create a B- SURFCAE.
- Surface Gaps can be filled by using a fill tool and multi sectional tool
CREATING C- SURFACE:
- To use multiple extract tool on the class A surface
- The extract boundaries can be sweep at 90 degrees to the reference boundaries up to required length
SURFACE MODEL OF A CAR BUMPER:
SOLID MODEL OF A CAR BUMPER:
The bumpers are provided in front and back side of a vehicle has two main purposes: first is to absorb the energy generated during these kinds of slow speed impacts and secondly to protect the expensive parts like main engine parts, radiators and connected engine cooling mechanism, headlights, taillights
materials using
Bumpers of most modern automobiles have been made of a combination of polycarbonate (PC) and acrylonitrile butadiene styrene (ABS) called PC/ABS.
