I'm tasked with designing a lift system for a frame that goes around the outside of a 12" x 18" rectangular structure. Due to budgetary constraints, we don't have many choices and a pneumatic system is what we tentatively settled on.
The preliminary design has four air cylinders, one at each corner, and they are plumbed through a common manifold to a single control valve. Although the frame is guided with linear bearings at each corner, I'm still worried that one of the cylinders will get ahead of the others and cause the frame to seize.
After a few hours with Google and looking through several pneumatic handbooks, all I could come up with is using a pressure regulator or a flow control valve on each cylinder's inlet.
What is the accepted method for synchronizing air cylinders?
Thanks.
