The purpose of the work is to analyze the energy losses of compressed air in a pneumatic drive on the basis of simulated modeling of thermodynamic processes of a body of variable mass,. Calculation of compressed air consumption when the drive is activated, determine the efficiency averaged over the cycle. Determine the optimal energy-saving scheme of the pneumatic drive. Choose the optimal control algorithm of the freely programmable pneumatic drive. Research methods - simulated modeling of thermodynamic processes of a body of variable mass to build a mathematical model of a pneumatic drive. Runge-Kutt integration method for numerical integration of mathematical model equations. An analysis of known designs of pneumatic drives and methods of their positioning was carried out, and an assessment of the effectiveness of their use under conditions of large inertial loads was made. An effective technical solution for the construction of a pneumatic circuit with an optimal structure of switching connections has been developed. Mathematical models are proposed that describe a two-way pneumatic drive. It is substantiated theoretically and numerically by applying the developed pneumatic scheme with an optimal structure of switching connections in order to ensure high speed performance in the entire range of inertial and static loads with smooth, shock-free operation of the pneumatic drive with equal deceleration and adjustable braking mode.
