The article is devoted to the analytical calculation of the main parameters and dimensions of a pneumohydraulic hydraulic shock damper with a decrease in pressure installed at the beginning of a pressure pipeline to reduce the emergency consequences of the intensity of shock waves, taking into account the polytropic process of air in the damper. Based on the results of analytical studies of the wave equations of non-stationary pressure movements for the proposed hydraulic shock damper, dependences were obtained for calculating the maximum and minimum impact heads in the first period of pressure fluctuations, considering the polytropic index.
To substantiate the reliability of the proposed dependencies and the economic dimensions of the damper design, comparative calculations of analytical studies with experimental data and data from other authors were performed. Comparative calculations prove the reliability of the proposed dependences obtained by the analytical method of solutions to the known equations of motion of hydromechanics, continuity, and state of the air in the damper.
