About Us

Baja SAE (Society of Automotive Engineers) is an intercollegiate design competition that provides an opportunity for students from around the world to apply their engineering skills. The University of California, Irvine’s Anteater Baja Racing Team Students are tasked to design, build, test and market an off-road vehicle that can withstand the harshest elements of rough terrain. The annual competition challenges 100 collegiate teams from all over the world to compete in a series of static and dynamic events. This year, our team will be running the Vandal Mark II in the competition.

Project Subsystems:

Our team members are divided into 5 subteams: Chassis-Body-Ergonomics, Brakes, Front Suspension and Steering, Rear Suspension, and Powertrain

Chassis-Body-Ergonomics

Objective: The chassis is the physical structure of the car: it is the skeleton that mounts the suspension, powertrain, steering and everything else that makes up a running car. The chassis sub-team's objective is to design, manufacture, and verify a lightweight but robust chassis that mounts the other subsystems with proper triangulation.

Tasks:

Design:

CAD a design in Solidworks, do Finite Element Analysis, and consult with other subteam leads for packaging their subsystems.

Manufacture:

Profile and bend metal tubing, make jigs and align tubing, and weld it all together.

Verify:

Check alignment, weigh the chassis, do torsional rigidity tests, and check with other subteams that their subsystem components fit.

Brakes

Objective: The brakes system is critical in the safety of the vehicle. The brakes team had three requirements they needed to meet: Design a braking system that is capable of locking all four tires traveling 30mph, design a system to distribute braking force between rear and front and design and manufacture mounts to attach brake system to vehicle

Tasks:

Design:

  • Master Cylinder – Pedal presses pistons in creating pressure in hydraulic lines
  • Front Calipers – Hydraulic pressure pushes pistons to squeeze against the rotor attached to front hubs. Front hubs allow rotor to transmit braking force to wheels
  • Rear Caliper – Hydraulic pressure pushes pistons to squeeze against the rotor attached to the output shaft.

Manufacture:

Machining, Waterjet, Welding, and useConduct a brakes test to verify all 4 wheels lock of power tools such as the angle grinder.

Verify:

Check alignment, weigh the chassis, do torsional rigidity tests, and check with other subteams that their subsystem components fit.

Front Suspension and Steering

Objective: Will use knowledge of vibrations, geometry, and force distribution to design efficient, strong, and easily manufactured systems. It is important to have a vehicle that is both maneuverable and capable of handling rough terrain. Must work with powertrain and brakes for front axles, differential, Must work with powertrain and brakes for front axles, differential, brake pedals and steering placement.

Tasks:

Design:

Steering mechanism and placement (ex: rack and pinion), design independent suspension system.

Manufacture:

Machining, Waterjet, Welding, Profile and bend metal tubing, and use of power tools such as the angle grinder.

Verify:

Test actual turning radius and steering effort.

Rear Suspension

Objective: Must design suspension so that the vehicle is able to withstand the harsh environment of off-road competition and recreational driving. The vehicle needs to traverse over large rocks, downed logs, mud holes, steep inclines, jumps, and off camber turns. Must also work with powertrain subsystems to agree on design of the axles, track width and wheel travel.

Tasks:

Design:

Independent suspension system components such as trailing arms, lateral links, and rear shocks. Design suspension geometry

Manufacture:

Machining, Waterjet, Welding, Profile and bend metal tubing, and use of power tools such as the angle grinder.

Verify:

Verify wheel travel, track width, toe and camber

Powertrain

Objective: Powertrain members are responsible for selecting the appropriate gear reduction for high acceleration and torque performance with the given Briggs Stratton Engine. Other decisions to make include the selection of axles that can handle the instantaneous torque exerted on their system and the linkage system used to engage the vehicle in four wheel drive (drive shaft/chain, differentials).

Tasks:

Design:

Using knowledge of engineering principles and problem solving to create a component/assembly to address a need for the vehicle such as acceleration and torque. Involves research, analytical thinking and problem solving, the use of CAD software, FEA, etc.

Manufacture:

Machining, Waterjet, Welding, and use of power tools such as the angle grinder.

Verify:

Verify dimensions and wheel travel and conduct a series of small tests to confirm the powertrain system will work appropriately before running the car for the first time.
