Представлено математичну модель механізму склоочищення в середовищі Matlab/Simulink та проведений його кінематичний синтез. The four-link mechanism of the car's mechatronic windshield cleaning system is substantiated using different ratios of links and analysis of their kinematic and dynamic characteristics. A mathematical model of the glass cleaning mechanism in the Matlab/Simulink environment is presented and its kinematic synthesis is carried out. A mathematical model of the movement of the brush on the glass was developed for the case of close to uniform pressure distribution along the length of the brush, taking into account the unevenness of the law of movement associated with the operation of the transmission mechanism. The influence of the material properties of the rubber element on the quality of glass cleaning and the obtained values of the values characterizing the elastic and dissipative properties of the neck in the limit modes of the system are considered. The possibility of regeneration self-oscillations is shown when the dissipative properties of the neck are reduced as a result of wear or an aggressive environment. The processes of dry friction and hydraulic movement resistance occurring in the system are clarified, the limits of possible visually noticeable self-oscillations depending on the parameters of the friction mode and system operation are shown. It was found that the presence in the system of the possibility of regenerative selfoscillations in critical operating modes requires the introduction of micro-oscillations into the law of movement of the brush on the glass, which can effectively reduce the amplitudes of these self-oscillations. Analytical dependencies are proposed for calculating the parameters of the software, which implements the management of the dynamic characteristics of the system by superimposing the law of motion of microoscillations. The necessary hardware and software requirements for the controller are shown, as well as the possibility of saving the windshield wiper control unit as a functional unit of the mechatronic system for ensuring the comfort of movement.uk-UAмехатронна системамоделюваннямеханізм склоочищенняавтомобільщіткигумовий елементпередатний механізмкут відхиленняmechatronic systemmodelingwindow cleaning mechanismcarbrushesrubber elementtransmission mechanismdeflection angleArticle
