1. MALWA INSTITUTE OF TECHNOLOGY, INDORE MINOR PROJECT PRESENTATION ON FSAE SUPRA VEHICLE Guided By:- Vikas Sharma Asst. Prof. (Dept. of Automobile Engg.) Submitted By: - TEAM AUTO VARP Aayush Verma Priyesh Patel Rajat Sharma Vijay Pratap Tomar 4 th Year (Dept. of Automobile Engg.)

2. CONTENT Introduction Literature survey Problem identification Aim and objective Proposed solution Conclusion References

3. INTRODUCTION Formula SAE is small Formula-style race car. The prototype race car is to be evaluated for its potential as a production item. Each student team designs, builds and tests a prototype based on a series of rules, whose purpose is both performance and ensuring track safety.

4. LITERTAURE SURVEY S.No . Paper/ Book Name of author We extracted 1. Design and Construction of a Space-frame Chassis Brendan. J. Waterman University of Western Australia Focuses primarily on space-frames, readily available materials used 2. Design of Student Formula Race Car Chassis Abhijeet Das University of Pune IJSR Design Considerations & Material Properties 3. Tune to win Croll smith AERO PUBLISHERS, INC Suspension, Brakes

5. PROBLEMS IDENTIFICATION • Dealing off with material and manufacturing costs • High Cost of manufacturing Aero dynamics drag Safety at high speed

6. AIMS & OBJECTIVES To design light weighted vehicle To maintain low cost but better reliability of the vehicle with impressive performance To enhance the safety features of the vehicle by adding some safety constraints and using proper materials Minimize the weight to stiffness ratio Maintain Low Center of Gravity Aesthetically pleasing design

7. PROPOSED SOLUTION Vehicle ground clearance is kept as low as possible Giving appropriate space for driver Using push rod suspension Enhancing safety features by adding engine kill switches and fire extinguishers.

8. SAFETY FEATURES Kill Switch Cross Seat belt Fire Extinguisher Side Glass Head light Tail light Indicator Light

9. ERGONOMICS Angle b/w upper arms and lower arm : 90 degree Seat angle : 50degree Thigh angle : 50 degree Steering wheel height : 250mm Knee height : 370mm Width of leg : 350mm Leg angle : 100 degree angle

10. INOVATION Using ram air induction for improving efficiency in low cost Adjustable ABC

11. FRAME & CHASSIS FRAME The body and engine are usually mounted to the top of the chassis with the suspension being mounted below CHASSIS  The  frame,   engine and suspension as one complete unit The   frame of the car with the drive-train and suspension being considered entirely separate items throughout this project, where  the  terms  “chassis”  and  “frame”  mean the same thing are interchangeable .

12. FRAME DESIGN

13. DESIGN CONSIDERATION * Stiffness of frame Torsional stiffness Triangulation law Suspension points Safety Driver position and control Ref. Brendan. J.

15. FRAME Over all length 3725 mm Over all height 528.51mm Over all width 3725mm Over all mass 73.633kg Ref. 2015 Formula SAE® Rules

16. ANALYSIS OF FRAME

17. ANALYSIS OF FRAME Front Impact Force applied 8000 N Stress generated 274.36 Mpa (max.) Yield strength 480 Mpa Factor of safety 1.74

18. VEHICLE * Over all length 4120mm Over all width 1800mm Over all height 900mm Ref. 2015 Formula SAE® Rules

19. BRAKE SYSTEM * Brake is a mechanical device which applies force against the direction of motion of the body. Due to this force, vehicle prevents from motion TYPES OF BRAKES Drum brake Disc brake Ref. Croll Smith AERO PUBLISHERS, INC

20. BASIC CONCEPT The brake system converts the kinetic energy of vehicle motion into heat

21. ACTUATION SUB-SYSTEM Brake Pedal Master Cylinder Proportioning Valves Brake Lining

22. DISC BRAKE

23. DISC BRAKE

24. BRAKE FADE Brake fade is the loss of performance resulting from the lining friction decreasing as the lining and rotor or drum rises in temperature

25. WHEEL AND TYRE Tires for our vehicle Diameters: 12.0'' - 12.0'' Width (mm): 145 - 145 Tire aspect ratio (%): 70 - 70 Smallest tire size: 145/70R12 Largest tire size: 145/70R12 Rims for our vehicle Bolt pattern 4x114.3 Diameter: 12.0'';   Width (inches): 4;   Offset (mm): 45.

26. STEERING SYSTEM Steering  is the mechanism It allows any vehicle (car, motorcycle, bicycle) to follow the desired course Primary purpose of the steering system is to allow the driver to guide the vehicle

27. COMPONENTS OF STEERING SYSTEM The  steering system is combination of : Steering wheel Steering column Steering box Tie rod Wheel hub

28. WORKING OF STEERING On steering the steering wheel torque provided is transmitted to wheels via. various linkages.

29. SUSPENSION * Suspension is the combination of : Spring Shock absorber Push rod Control arm Wheel Ref. Croll Smith AERO PUBLISHERS, INC

30. PURPOSE SUSPENSION SYSTEMS Vehicle's road holding/handling. Keeping vehicle occupants comfortable and a ride quality.

31. TYPES OF SUSPENSION Dependent Suspension System Independent Suspension System

32. OUR PROPOSED SYSTEM We are using independent double wishbone pushrod type suspension.

33. POWER TRAIN OF OUR * VEHICLE Engine ID : Suzuki F8B (Made in Japan ) Engine Type : 4-stroke cycle, water-cooled, OHC Cylinders : 3 Lubrication Type : Wet sump Piston Displacement : 796cc (48.6 cu-in) Compression Ratio : 8.7 : 1 Max.
