The study objective is to improve the operational characteristics of hydraulic drives. The task to which the paper is devoted is to simulate operating processes and minimize the vibrations of the drive hydraulic and mechanical components based on the analysis of the main types of generators and dissipators of acoustic vibrations in hydraulic systems. Research methods: analysis of complex multidisciplinary models of hydraulic machine operating processes. Macro-models provide solutions to problems at the system level. Micro-models provide an analysis of the operating processes of hydraulic drives, taking into account the influence of internal and external factors of impact operating, the interaction of components and parts, changes in structural and technological parameters. The novelty of the work is in the substantiation of the influence of operational factors, structural and technological parameters on the vibration processes that form the acoustic characteristics of the hydraulic drive. The results of the study are presented on the example of reducing the vibration processes of an axial plunger hydraulic machine. Fluctuations in the operating pressure are given in the indicator diagram. The vibration amplitude depends on the dead volume of the piston chamber, as well as due to its under-filling operation at low temperatures. Also, based on the simulation results, zones of energy dissipation of the working fluid are localized to reduce vibration processes. Conclusions: the obtained results of modeling various measures to reduce the vibration processes will allow to localize and reduce the negative factors of noise generation.
