The hardware of the virtual instru ent was configured and the software was designed by LabVIEW. The CAT syste can test pressures at inlet, outlet and cushion cha bers, output force, piston displace ent and shock acceleration of a pneu aticcylinder and plot corresponding result graphs Experi ents indicate that the CAT syste is convenient to operate and has high. , easure ent precision and wide practicability. It applies to the easure ent of cushion charac- teristics, velocity characteristics and transient characteristics of pneu atic cylinders.
