Systems Architecture

Utilizing the current KGCOE dyno system the team has drafted new system level design concepts for the mechanical aspects of the project. The electrical system level design has not changed along with the focus of the project as we are still looking to gather the same data and controls.

Ideas for Transporting and Utilizing the Hot Wheelz Powertrain System
Usable Space to Place Powertrain Cart in the Dyno Room

Usable Space to Place Powertrain Cart in the Dyno Room

Concept Drawing of Portable Cart to Hold and Transport the Hot Wheelz Powertrain System. This way the team could easily move their system from their team room to the testing platform in a safe and convenient way. The cart rigidly holds the batteries and controller of the Hot Wheelz System during transportation and testing. It also features a bracket to carry the motor and baseplate during transportation and storage of the system. The cart will be electrically insulated from the battery system for safety purposes.

Coupling between the Hot Wheelz Motor and the Dyno
Current Motor Coupling Solution used by the RIT Formula SAE Team. Moving forward our group has decided to incorporate a similiar chain drive with the proper gear ratio to replicate racing conditions as much as possible. An idler will be added for to easily tension the chain and disassemble the system after testing.

Risk Assessment

Our team has identified possible risks that need to be accounted for in the design, build and use of the test bench. We have given each risk a different level of importance so that we know what to focus our efforts on in order to avoid to minimize error and accidents throughout the process.

Subsystem Design Review

Our team assembles a conclusive presentation at the end of each review to summarize our work which is located here: Phase 3: Subsystem Design Review Presentation
