Variation coefficient of torsional vibrations of the connection nodes of vibrating machines

Purpose. To formalize the dependence of eigenfrequencies translational and torsional vibrations structural elements vibrating machine articulated by connection node on their design parameters mechanical characteristics, as well regulatory requirements for vibration activity, strength accuracy. develop a method selecting elastic band element package, taking into account specified values amplitude frequency characteristics dynamic loads reproduced supporting structure coefficient variation natural frequencies vibrations. Methodology. The research is based fundamental approaches applied mechanics, dynamics reliability. Findings. dependences body parts connected are obtained analyzed. Vibrations around an axis orthogonal to working direction considered. A comparative analysis in transmitted its circular from elements, number package packages performed. Originality. It fact that first time describing machine, obtained. Also paradigm choice which results directions through innovative. This made it possible include criterion reproduction accuracy, formalized variation, together with criteria rigidity, methodology synthesis scheme machine. Practical value. proposed methodological solutions calculation selection tape ensure achievement activity indicators parts, ratio related at level normative documents when upgrading existing machines creating new modern equipment. As result, reliability, durability, safety, productivity load-bearing capacity machines, equipment mechanisms mining engineering, aviation, transport space technology increased.
