Scientific activity:
In candidate’s dissertation solved the problem of increasing the technical level of hydraulic pneumatic units through structural synthesis and dynamic analysis of rational schemes. A method for designing multi-cycle discrete-analog control circuits using valves with one-way control was developed, based on complete minimization of the standard positional structure, and including: a description of the operation of the hydraulic-pneumatic unit system; structural synthesis of a hydropneumatic unit; synthesis of a multi-cycle control scheme; synthesis of a circuit for a separate positional hydropneumatic unit. This method makes it possible to obtain circuits containing simple discrete hydropneumatic equipment, and does not require the use of complex servo proportional hydropneumatic devices. As a result of the research, a method has been developed for assessing the functional capabilities of the pneumatic unit, from the point of view of its dynamics, which makes it possible to assess the extent to which this pneumatic unit can ensure the performance of the characteristics necessary for the technological process, such as: speed, load capacity, accuracy of the reference signal, etc.
