3.  Accomplishments ◦ Finalized designs ◦ Ordered material ◦ Determined forces needed for stress analysis  Future Goals ◦ Complete Stress Analysis ◦ Complete manufacturing

4.  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.

5. 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.

6. ◦ 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)

7.  Accomplishments ◦ Input Geometry Into PATRAN  Future Goals ◦ Meshing ◦ Material Properties ◦ CBAR Properties ◦ Load Cases ◦ Analysis

8.  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]

9. 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.

10.  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

12.  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

13.  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 RPM FLOWRATE Theoretical (CFM) Engine Displacement 10002.644185925599 cm 3 15003.966278887 20005.288371849 25006.610464812 30007.932557774 35009.254650736 400010.5767437 450011.89883666 500013.22092962 550014.54302259 600015.86511555 650017.18720851 700018.50930147 750019.83139443 800021.1534874 850022.47558036 900023.79767332
