Annotation
A schematic diagram of adaptive friction contact of solid bodies with indirect regulation is proposed, according to which the adder is an integral part of an automatically regulated pressure unit. It is shown that the efficiency of using the setting influence is determined by the nature of the change in the mismatch coefficient. A condition for self-regulation of contact within the interval of change of perturbing influence is set. Research objective: synthesis of positive feedback and investigation of its effectiveness in synthesized adaptive frictional contact. Methods of mathematical modeling allowed to create a knowledge base in the form of private mathematical models that locally describe the process of automatic regulation in the control device. Results of the study. The principal possibility of applying synthesized structural-functional and schematic diagrams of the control device with positive feedback in couplings for maintaining their high accuracy of operation is determined. The regularity of the control action formation in function of the disturbing influence is obtained, and the parameters of the control device are identified. The obtained results can be used in the practice of design and calculation of adaptive friction clutches with positive feedback.
Conclusions. To ensure self-regulation over the whole interval of the disturbing influence and the effective useof the setting influence, a constructive realization of the control device is required in accordance with the found dependences between its parameters.
