The article analyzes the elements of the magnetorheological drive systems. It is examiningthe way of the regulating of discharge in the control flow path by means of magnetorheological
control device and is provided the method of workflow automation for magnetorheological control device. It describes the ways to implement the transmission of control signals and reverse communication by pressure. It presents the method for the calculation of control signal by microcontroller and the example of one control algorithm.
The text covers the electrical schematic circuit diagram for workflow of magnetorheological
control device; this allows the use of the magnetorheological control devices in the actuators of
automatic and mechatronic systems. It describes the way to implement the workflow of magnetorheological control devices by means of differential pressure gauge. It also describes a functional scheme the operation of the differential pressure gauge.
The authors offer the hydraulic schematic circuit diagram to include the magnetorheological
control device in the control magnetorheological flow path with the thermostatic system which
allows the temperature regulation of the rheological properties of magnetorheological fluid.
It presents the method to implement the temperature control of working fluid in the magnetorheological systems. It is discussed the features of thermostatic control systems which is established on the basis of thermoelectric semiconductor elements. It describes the advantages of the using of proposed system. It shows the static characteristics of the magnetorheological control devices in automatic mode of fixed flow characteristics. It is analyzed the results of field experiment and made a comparison with the results of numerical modeling of workflow for magnetorheological control devices. The effectiveness of a method of workflow automation of the magnetorheological control device is confirmed with calculations and experiments.
