Consider a balloon, it is a flexible, expanding pressure vessel made of synthetic rubber. I am trying to design a system that will use hemispheric pockets of neoprene to grip an object, much like the one found in this journal:
H. Choi and M. Koç, 'Design and feasibility tests of a flexible gripper based on inflatable rubber pockets', International Journal of Machine Tools and Manufacture, vol. 46, no. 12-13, pp. 1350-1361, 2006. (Behind a paywall, abstract available here)
Although I am not entirely certain where to start, I am dealing with a high pressure (8 bar) and need to work on a small scale (max radius of 40mm).
Values I have recieved from equations found online suggests thickness values in meters and radius expansion reaching the hundrends of meters.
What equations do I need to calculate a solution?
Are neoprene, latex and chloroprene viable materials to use or should I find alternatives?
Is a hemisphere that best pocket shape I can use?
Additionally, how can I calculate the amount of expansion?
