Abstract (English):
The study objective is synthesis of the control structure diagram of an adaptive elastic and safety friction clutch with positive feedback based on V-shaped elastic elements and determination of the optimal parameters of the system. The task to which the paper is devoted is the development of structural and functional diagrams of an adaptive friction clutch with positive feedback. Research methods: previously applied theory of complete limit torque stabilization of an adaptive elastic and safety friction clutch with positive feedback made it possible to create mathematical models that locally describe the process of automatic regulation in the control device. Based on the analysis of the mathematical modeling method, the possibility of using synthesized structure diagrams of positive feedback acting in the entire range of changes in the friction factor or in its most parts. The novelty of the work is connected with finding the relations for calculating the optimal parameters of the feedback control device, which allow to increase the stability of the transmitted load. Research results: structural and functional diagrams of an adaptive elastic and safety friction clutch with positive feedback based on a flexible console of variable length with a "negative" initial angle of inclination are developed. A dependence is obtained that allows determining the maximum load of the clutch at different values of friction factor. Conclusions: high reliability of the adaptive elastic and safety friction clutch of the third generation is theoretically ensured by the synthesis of a control device with V-shaped elastic elements.
