Polylogix is a team dedicated to the design, build, and testing of a fatigue machine to simulate cyclic loading on a biomedical polymer. This project is sponsored by Endologix, Inc. to provide test data characterizing mechanical material properties of various formulations of polymer used in abdominal aortic aneurysm surgeries. With this project goal, the machine must be able to test the polymer at body conditions; these include a testing temperature of 37°C and a cycling frequency ranging from 1 Hz to 10 Hz. This report proposes the following solution to this design challenge: an AC motor-driven mechanism utilizing a planetary …

Our group was presented with a challenge to design an automated machine to replace Micro-Vu’s current manual pressing operation. We moved, planned, and scheduled our tasks for the three quarters we will be working on this project by using a Gantt chart. In designing the machine, we generated concepts and used analysis and prototyping to select the most promising ones. Our final design uses a pneumatic press to press the parts, and it includes magazines to hold the parts before pressing, pneumatic actuators to move the parts to and from the pressing location, and a lever to separate the defective …
