Problems of Modeling Working Processes in Pneumohydraulic Systems and Units at Various Stages of the Product Life Cycle

The article presents the result of the analysis of the problems of maintenance of on-board pneumatic systems and units in terms of the requirements for completeness and efficiency of the requested information. It is shown that the current state of the workflow modeling tools of these systems do not fully meet the maintenance requirements at all stages of the product life cycle. An approach to modeling pneumohydraulic systems and units is proposed, as well as ways to reduce the time from the moment of setting a problem requiring the development of a new mathematical model to obtaining adequate simulation results. The efficiency of the proposed approach is demonstrated by the example of a pressure regulator operating in a dynamic mode. The possibilities and ways of implementing modeling tools based on the proposed approach are shown.
