Апстракт
The digital signal processing based on new microprocessor technology allows us great success in machines protection, with very acceptable economic investments today. Additionally, including vibration-diagnostics monitoring of machines in addition with analytics methods, it is possible monitoring and quantification dynamics parameter of machine. By means analysis dynamics behavior of rotor, it is possible diagnostics defect which relating on rotor and other parts of machine, and solve it. In last time, vibrations analysis and monitoring are become the most wide spread and softest part of machines diagnostics. Detection, identification and removing of problems about work of machine is simpler if we modeling few dynamics solution. When forming model which oriented on discovering defect by means sensors measured vibrations, which almost located in bearings, mathematics model is presented as elastic rotor with concentrated weight. Experimental results from test tables leading company in the world Bentley Nevada Co. USA used as base for development of this model. As note, mathematics model in the most cases based on radial oscillation of rotor and torsion oscillations in someone cases. Torsion vibration are not detect without special sensors even if they are his magnitude near destruction level.
