THE METHOD OF CALCULATING THE BASIC PARAMETERS OF THE MANUAL HYDRAULIC CUTTER-SPREADER TOOL
This paper presents a method for calculating the power characteristics of hydraulic combined cutters spreads for rescue operations in emergency situations. A kinematic scheme of cutters has been developed and based on its mathematical description the dependences of the expansion force on the angle of opening of the cutters’ jaws and the efforts of tightening have been obtained. The diagrams of these dependencies are constructed. The dependences of the cutting force of the reinforcement on the angle of the cutters’ jaws opening are established, and diagrams of these dependencies are constructed when cutting rods of different diameters.
