Abstract
This paper investigates an innovative hydraulic system with two degrees of freedom and a single input, featuring a patented closed hydraulic circuit. The adaptive hydraulic mechanism of this system is analyzed, showcasing a unique force adaptation effect. The speed adjustment of the output piston in the adaptive hydraulic mechanism depends on the current load. Upon reaching a predetermined resistance to movement, the output piston stops, transitioning the mechanism into a single-degree-of-freedom mode, while the input piston continues its motion. The effective force adaptation of the hydraulic system provides automatic regulation without the involvement of a control system. Our research aims to experimentally confirm the force adaptation effect in the proposed hydraulic mechanism and to provide a detailed description of the fundamental principles of its operation.
