Ryan Baldi is currently in his fifth year of team membership. He has held positions as the chassis welder, the Fabrication Group Leader, the Engine Group Chief Engineer, and competition driver. He is currently the team's Chief Engineer.
Interview SummaryWhere: 09-2325
When: 7pm 10/30/08
Why: Initial needs discussion
- FSAE Team currently spend large amounts of time and
money cutting tubes, designing and fabricating jigs, and
welding the chassis. In addition, accuracy of suspension
points and chassis nodes due to tolerance stack-up is not
- CNC machined plug templates or molds for composite chassis could reduce chassis lead time while increasing complex contouring capabilities and suspension point accuracy.
- In order to reduce chassis 9lbs of chassis weight
over the last two years, the team has sacrificed
300lb*ft/degree of torsional chassis stiffness.
- Composite chassis could potentially reduce weight by 10-15lbs while INCREASING chassis stiffness (ideally increased to 2000lb*ft/degree).
- Potential drawbacks to composite chassis:
- Must be joined to steel roll hoop and steel rear box. Joint methodology? Can not weld. Adhesives are difficult to inspect and ensure quality. Bolted joints are difficult to predict in composites.
- Structural equivalency tests must be performed to prove composite monocoque is safe in competition.
- Skillset of designers and manufacturers differs greatly from tradition steel tube chassis personnel.
- Aero package would be great. Competition teams claim 25lbs of downforce at skidpad speeds (~30mph).
- Aero package is very low risk. Added weight is below the CG of the racecar and acts with a rear bias. Can easily be detached if it is undesired.
