Wheel Arch Challenge
Wheel Arch Area:
- The Wheel Arch area of the Fender is usually designed for the purpose of protecting the BIW from stones and other objects on the road as well as the Pedestrians.
- To Check the clearance between the Fender and the Wheel,there are certain standards all over the world,They are
- American Standard
- European Standard
- Japanese Standard
In this Challenge we are going to check the Wheel arch clearance based on the Europen Standards.
The Standards commonly used are,
- The Standard that we are using here is European Standard,
- The Main objective of this Standard is that the outer edge of the fender and wheel should have a clearance between them,For European the Clearance should be greater than 10mm.
Procedure:
- Create the datum plane on the outer edge of the wheel.
- Create the centre axis.
- Create the sections SB,SA,SC,SD,SE.
- Create the section SB by creating a inclined line of 30° to the centre axis i.e SA
- Create the Section SC by creating a inclined line of 50° to the centre axis.
- The Section SE is created by placing the line on the fender at a distance of 150mm.
- The Section SD is created by the placing on the centre between the SC and SE.
- Now using the Law extension create the surfaces for esch section.
Now measure the clearance between the outer edge of the fender with the law extension\'s edge
