Abstract/Summary
The Baja SAE Gear Testing project outlined a test stand and procedure to update the S-N curve currently used by the Baja SAE team. Currently the Cal Poly Baja SAE geartrain team uses a S-N curve to design custom gears, but this S-N curve does not accurately reflect the gears uses and their fatigue life. This project outlines the exploration of a dyno set up to allow for future testing of different categories of short life cycle gears to collect data and generate a new S-N curve and, ultimately, update the design of the gears. This team created a dyno to allow for this testing as well as the testing plans and procedures that will allow future teams to test small versions of the on-car gears to build this desired S-N curve. The conclusion of this project is an assembled and working dyno that includes a gearbox that can accommodate all recommended gear thicknesses to test. The design and assembly of the dyno as well as the gear thicknesses recommended by this team to build an accurate S-N curve are all outlined in this report. To ensure that this project is continued it is recommended that the Baja SAE geartrain teams continue to manufacture miniature gears as recommended by this report and test these gears until failure in the dyno.
