In the first report, we proposed digital simulation methods which can account for compressor-piping interaction. These methods assume that the stiffness of gas in the compressor cylinder is constant. This paper describes the new compressor model in consideration of the nonlinear stiffness of gas in the compressor cylinder, in which, as in practical compressors, gas stiffness varies with the movement of the piston and the suction/discharge gas flow from/into the piping. By using the present model, the digital simulations were carried out for a compressor-piping system. From these calculations, it is shown that the present method can also deal with compressor-piping interactions, in comparison with the simulation results in the first report.
