Pneumatic cylinder is used for mechanical handling system. A mathematical model of a double acting pneumatic cushioning cylinder is presented, which is based on the following assumptions; ideal equation of state, isentropic flow through a port, conservation of mass, polytropic thermodynamics and piston dynamics. These differential equation can be solved through numerical integration using the fourth order runge-kutta method. An experimental study was conducted to validate the results obtained by the numerical technique. The computer simulation model presented here has been extremely useful in not only understanding the basic cushion mechanism but also in evaluating different designs.
