Abstract

A system of differential equations is derived basing on relationships for mass, energy and impulse balances to describe time changes of pressure and temperature derivatives for gaseous working substance in regard to various types of pneumatic systems. Numerical simulation of pneumohydraulic systems demonstrates a close fit between results obtained by mefns of suggested mathematical model and experimental data.
