The document summarizes a presentation on the design of an FSAE supra vehicle. A team of engineering students designed a small formula-style race car to meet competition rules while ensuring performance and safety. Key aspects of the design included a lightweight chassis, pushrod suspension for improved handling, and safety features like fire extinguishers. Analysis showed the frame could withstand significant impact forces with a safety factor of 1.74. The final vehicle design was 4.12 meters long, 1.8 meters wide, and weighed 350 kilograms.

3.  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.

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

6. • 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. 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.

 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.

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
1. Drum brake
2. Disc brake
Ref. Croll Smith AERO PUBLISHERS, INC

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

21. •Brake Pedal
•Master Cylinder
•Proportioning Valves
•Brake Lining

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

•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 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. The steering system is combination of :
1. Steering wheel
2. Steering column
3. Steering box
4. Tie rod
5. Wheel hub

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

Suspension is the combination of:
 Spring
 Shock absorber
 Push rod
 Control arm
 Wheel
