SIMULATION OF ACOUSTIC WAVE PROPAGATION IN HYDRAULIC CONTROL SYSTEMS WITH OBTAINING SPECTRAL CHARACTERISTICS OF SOUND POWER DISTRIBUTION IN THE SOFTWARE PACKAGE SIMHYDRAULICS MATLAB

Modern hydraulic systems are subject to stringent noise and vibration requirements. In the existing scope of work a lot of attention is paid to a variety of factors, often without taking into account their mutual influence. In General, they can be divided into schematic design, system and principle. Currently, the development of science and technology is at a level where further improvement of the acoustic quality of individual elements and systems as a whole is possible in the study of emerging processes at the intersection of Sciences. In this regard, the paper considers the possibility of modeling wave processes in hydraulic control systems with the subsequent obtaining of acoustic characteristics, which is a joint use of the mathematical apparatus of the control theory and methods of acoustics. The simhydraulics Matlab software package is considered as one of the most suitable means of solving the tasks. Along with mathematical models of control system elements, the paper proposes acoustic models of elements that are taken into account when modeling transients in the system. Based on the results obtained, additional criteria for assessing the quality of management systems are proposed.
