Solid Design, but hard to machine.
The integrated components would add
excess machining time and cost
• Separated Tie
Rod bracket
from main
upright.
• Retains the strength
and low weight of
original design
while lowering
machining cost.
• Low weight, fully
integrated design.
• Revised Design; Added Bracing in
lower portion for additional support,
while adding a negligible amount of
weight.
• Bolt on lower mounting brackets for
decreased machining time and cost.
◦ Equations used to calculate load on upright
•Function of Lateral Force on each tire as a
function of slip angle.
•For our purposes 500lb is approx. 2000N.
•2000/4 tires is closest to 600N (RED)

Using PATRAN/NASTRAN to model frame
Attempted using step file from SolidWorks
Current plan: model using CBAR which gives appearance
of wire frame
[Model of Imported Step File in PATRAN]
Future Steps Needed to Accomplish Frame
Analysis
•Analysis will be run using CBAR
•PATRAN will then recognize each curve as a
beam
•Material Properties
•Cross Sectional Area , ect.

Current Accomplishments:
 Ordered materials for intake
 Continuing flow analysis
Goals for the Future:
 Complete flow analysis
 Fabricate intake
 Flow bench testing of fabricated intake to
verify flow analysis

Initial Testing using SolidWorks FloXpress
Initial tests: flow was through one intake runner at a time
Testing in SolidWorks modified to flow all 4 runners at a time.
Goal is to verify that the intake does not choke engine air
flow
-Initial flow
models, one at
a time
-Modified test
flowing through
all intake
runners

Analysis(cont.)
◦ Flow rates obtained by SolidWorks flow models will be
compared to theoretical flow rates to determine
theoretical volumetric efficiency
◦ Real world Flow Bench testing in the future to determine
actual volumetric efficiency
