Abstract
In this article the dynamic processes in the drive together with the asynchronous engine, coupling with gas, and mechanical drive are considered. The coupling of this type consists of separate segments, where additional masses are input. The presented dynamic model of drive pressure wave propagation in gas, interaction of separate coupling bodies and gas. Gas movement in segments is described by the equations of continuity, movement quantity and gas state. This system of equations is solved by the method of characteristics together with the system of equations of asynchronous engine and mechanical drive, received non-linear equations are solved by Newton method.
