After much consideration, team FeraFree has decided to forgo physical simulation with the wind turbine replica bearing in lieu of simpler fluid calculations. This reflects limitations in budget, time, and a greater emphasis on producing a functional prototype. Consideration was also given to simulating the grease flow in a virtual bearing but that idea was also eliminated as the team does not have the prerequisite knowledge for complex simulation of that degree. Product design continues with passive grease collection as the primary method for sampling debris concentration, with a more mechanically involved collection method as a backup.
Software development for the microcontroller continues and cellular (LTE) functionality was confirmed, providing the route for sensor data transfer away from the installation site. Design of the printed circuit board for sensor data processing and power handling is nearing completion. Testing has begun with two sensors, attempting to use one as a reference signal to reduce noise and isolate the signals produced by the ferrous debris. Next week the team plans to continue sensor work and outline documentation required for the Final Design Review.
