To fully utilize the talents and abilities of everyone on the team, we structure ourselves into groups that work on specific aspects of the car. These are our Subsystems.
The Brakes Subteam designs a reliable hydraulic system to slow and stop the car based on driver input. The system works by converting kinetic energy to thermal energy. Pressure, wheel speed, and acceleration are investigated to validate and tune vehicle dynamics.
Design a frame that integrates the designs of all other subsystems into one cohesive vehicle. A tube frame that protects the driver in case of crash or rollover.
Integrate and utilize composite materials throughout the car in order to save weight while maintaining structural integrity.
Balance the speed/torque transmitted from the engine to the gearbox to maintain the engine at peak power and maximize the car's acceleration.
Electronics is in charge of obtaining data from multiple sensors integrated into the car, through the use of our Race Technology DL1 club DAQ. This year we hope to begin the foundation for our own DAQ, built-off of a microcontroller and custom libraries. In addition, we display valuable information to the driver during our testing days and in our competitions, that information is changeable based on the need of the driver.
ELECTRONS (DATA ACQUISITION)
In charge of data acquisition for Baja Team. Live feedback, and live display for driver
The goal of Ergonomics is to design components that integrate well with other subsystems to improve drivers' performance and comfort. Driver performance is crucial for our teams performance, especially in the 4 hour endurance race, since it's worth the majority of our points in competition. Integration with the other subsystems is also important because the driver doesn't interact with their components directly, instead Ergonomics bridges the gap between the driver and the other subsystems on the car.
The powertrain as a system controls the engine and uses its power to accelerate the car through the use of a continuously variable transmission (CVT), gear reduction box, and output shafts to turn the rear wheels. The CVT currently utilizes a Gaged Engineering CVT with a major focus on tuning to respond to any conditions the car sees and provide an optimal ratio for the situation. The student designed custom gearbox multiplies the torque of the Briggs and Stratton Model 19 and sends power through constant velocity joints to allow for suspension travel. Finally the custom hubs interface with ITP wheels and tires tailored for each competition to put the power to the ground.
Part inspection and jig design.
The baja car's steering system consists of an aluminum rack and pinion interface, designed to provide tactile feedback and predictable handling for the vehicle. Steering assists suspension in creating favorable vehicle dynamics, with the main goal of preparing the car for the maneuverability event at competition.
The Suspension Kinematics Subteam is responsible for developing tests to manipulate suspension parameters with the intention to create performance curves. These curves are then used to create a compliant and maneuverable car.
Design and test suspensions components to maximize performance while maintaining a robust, light weight system.
The shocks sub-team of suspension is tasked with designing and implementing testing to determine event specific shock tuning ultimately for the purpose of producing a reliable system with versatile performance. Compression and rebound damping are adjusted to maximize driver confidence and to enhance kinematic characteristics determined by suspension geometry.
