Ring wear test device

Ring wear test device

Testing and validating were required by the material science department group that was developing O-Rings on the brass piston seen below. The device needed to fatigue the piston with fluid on both sides. This system utilized an Arduino to count the number of cycles, monitor load on the piston and display the load vs time. This is valuable information to have because as you can see in figure 4.2 the load increases per cycle, this is the expected result with the type of rings they are using. Next, after a specified number of fatigue cycles, the system would perform a pressure decay test. This test would act as a validation for the rings to compare the pressure decay to stock rings as well as compare the decay from different cycles.

Glass flexural strength teaching aid

Glass flexural strength teaching aid

The intro to Material Science class that all ME and MS majors take wanted a cost-effective and easy way to give a hands-on explanation for how to calculate flexural strength. Through gathering desired traits from Dr. Moll, I designed a system that could sit on the student’s desk and the students could use it to calculate the flexural strength of glass slides. The benefits to this project were each system cost around $50 and are mostly 3D printed parts. The Arduino reads the load and will display that as well as the deflection for the students to use in their calculation. We ended up making multiple units so all the students can do this exercise at once. On one of the devices, I also installed a humidity sensor and humidifier so the students can witness the effect moisture has on the surface tension and flexural strength of the glass.

Soil Nutrient Delivery System

Soil nutrient delivery system unit

Research being done by Dr. Chittoori had the need to deliver a nutrient to a soil sample. The System was designed and FEW was performed to ensure the system would hold up to required pressures. Multiple units were made after initial testing and are in use in Dr. Chittoori’s lab. The COEN ITS team generated operation manuals for these as well.
