Project Name: Biaxial Tissue Stretching Device
Group Number: 30
Group Members: Krista Vedvik, Christopher Zarins, and Joshua Leibowitz
Current status of project:
We have fully developed the linear rail design with several design elements (e.g. drive mechanism, membrane fixation, etc.). Several other designs have been drafted that will be further explored in the coming week. Once these additional designs are fully developed, Pugh charts will be used to determine our final design.
Work completed in the last week:
· Drafting of major designs as per combination table
· Full development of linear rail design
· Exploration of various membrane fixation strategies
· Set up parameters for finite element analysis
Work planned for next week:
· Run finite element analysis
· Quotes for the following
o Linear rails (rod vs. track)
o Linear actuators
o Male-Female threaded standoff
· Fully develop additional designs (cam-drive, mechanical linkage, etc.)
· Get info on proper membrane stiffness
Anything needed from client or TA or instructor to continue work:
Attn: Dr. Yin,
What is the relative importance of being compatible with the upright microscope? A potential design has a rail system above the media bath and membrane and may interfere with the microscope depending on its size. We believe the design in which the drive mechanism is above the bath will be easier to implement and will be more accurate, but how heavily is this weighed against compatibility with the microscope?
Also, to run finite element simulations this week, we need an approximate stiffness for the membrane. Do you have more details about the membrane used in prior work?
