Abstract
The paper concerns the construction and the simulation testing of a motion synchronization system of two pneumatic cylinders operating parallelly under different loads. The sinchronizer comprises the fluidic amplifier controlled by the slidingspool valve distributing the air flow into the cylinders. The fluidic amplifier is controlled by the pressure signal from the valve output.On the basis of the mathematical model the simulation of operation of two cylinders working parallelly with synchronizing valve has been carried out. The results has been compared with the simulation of two cylinders working parallelly without synchronizing valve. The aim of the simulation testing was to optimize the construction of the synchronizing system.
displacement of the piston rods of both cylinders x1/t/, x2/t/ on the way cylinders stokes.
The experimental results allow to state that aplication of the synchronizing valve with the fluidic amplifier essentialy improves the characteristics of the system, decreasing the displacement difirence of cylinders by about 50 /e.g.for the load difference 900 N, the displacement difference is 21, while the system without synchronization showed the difference of 43%/.
The selection of the amplification factor of fluidic element and of the springs which holding sliding spool in midposition has the most important influence the working of the synchronizing system.
