Re: hydraulic actuators-mechanical synchronization
I guess the disadvantage is you rely on the hydraulic pressure to be perfectly equal in each cyl, or that the weight will be the same on each cyl.
Although if coupled, the pressure should equalize?
I was once involved in one system that had four cylinders that were used for raising a R.R. box cars, one cylinder in each corner and four valves, so a encoder on each ram was used to monitor each lift rate and modify flow to keep each equal, but there was quite a high degree of sophistication for this method.
