Abstract: Cushion
is a key problem to develop high-speed pneumatic cylinder. Through
studying the cushion course of high-speed cylinder the piston velocity
rebound during the stable phase is found. The main course of this
problem is analyzed and the cushion system is designed which includes
cushion valve with an unchangeable chamber and overfalling valve and
exhaust valve. Experimental and simulation results prove that this
cushion system can solve this problem effectively and has enough
automatic adaptation ability for piston speed change.
Key words:High-speed
