Project Name: Biaxial Tissue Stretching Device
Group Number: 30
Group Members: Krista Vedvik, Christopher Zarins, and Joshua Leibowitz
Current status of project:
Progress was made towards a final design using four linear actuators to control stretching. Suitable linear actuators were found from Ultramotion, and quotes were obtained. Two alternate fixation mechanisms were considered, using clamps and posts. Finite element simulations will be performed to elucidate their feasibility of application to this project.
Work completed in the last week:
· Selected linear actuators and got quote from ultramotion (discussed design with engineer to ensure compatibility with incubator)
· Researched physiological fluid shear parameters to verify that fluid shear on membrane will be negligible
· Drafted modified pole and “hook” fixation mechanism designs
· Met with client to discuss analysis performed to choose final design
Work planned for next week:
· Finalize major parts list
· Get quotes on non-custom manufactured major parts (linear rails, etc.)
· Finite element simulations of modified pole fixation mechanism
· Calculate approximate fluid shear from simulations
· Research possible materials for bath
Anything needed from client or TA or instructor to continue work:
No
