To redesign the front suspension rocker as long as the 4 Delphi Panther Racing Indycar

Donoghue, Andrew, Contributing Writer has reference to this Academic Journal, PHwiki organized this Journal To redesign the front suspension rocker as long as the 4 Delphi Panther Racing Indycar. To reduce weight of front rockers by ½ a pound each. Constructed using Aluminum rather than Steel. Rocker used in front suspension as long as Indy Racing League Maximum Load = 7000 lbs Verified by DAG team at Panther Racing Constructed rocker in Pro-engineer Analyzed in ANSYS Workbench Analyzed stresses on steel rocker Resigned rocker in order to minimize stresses Constructed rocker from Aluminum

Redesigning the front suspension rocker has given Panther Racing an edge on the competition by reducing the weight of the car while keeping the driver safe. Even though it is a very small amount of weight that is being lost, anything that can be lost from the car in terms of weight can give that extra thous in addition to th of a second that is needed in order to beat the competition. Modifications of Original Steel Rocker reduced stresses by approx. 30% 7000 Series Aluminum could successfully be used!
