Abstract

The report discusses the transition of hinge-lever mechanisms from one structure to another and the use of these properties to create machines for various purposes. Our research has shown that when some parameters or their ratios change, conditions are created for a possible change in the structure of the mechanism. One of the schemes of hinge-lever mechanisms of variable structure was used in the design of the drilling module as part of the Luna-24 station for drilling a hole on the surface of the Moon, as a generator of power pulses. A major application of lever mechanisms of variable structure was their use as a working body in pressure presses. The report outlines the stages of creating impact machines based on mechanisms of variable structure, from hand-driven perforators to hammers with high impact energy. The design research was accompanied by studies of the kinematics and dynamics of impact machines with mechanisms of variable structure, the identification of new properties, the synthesis of the most optimal design and operating parameters of the power transmission.
