The main tasks of automated control and diagnostics of the technical condition of hydraulic drives are formulated, criteria for assessing the technical condition of a hydraulic drive as a whole and its individual devices are considered, examples of test operating modes for hydraulic drives with a guide and proportional hydraulic equipment are given.

A complex of formulas is presented, the consistent application of which allows, based on the given characteristics of the sinusoidal law of variation of the internal pressure in the test pipe, to calculate and select the main parameters of the hydraulic system of the test bench. An example is given of using a simple method for checking the correctness of the choice made.
