ЯНОТА ПРОГНОЗНЫЙ КОНТРОЛЬ РАДИАЛЬНЫХ КОЛЕБАНИЙ РОТОРА В статье рассматривается конструкция системы контроля вибрации при применении ротора, в которой должны учитываться различные параметры такие, как критическая скорость, намагничивающая сила, нестабильность и т.д. <...> Ключевые слова: прогнозный контроль, колебания, ротор INTRODUCTION The goal of this work is the design of predictive vibration control systems for rotors. <...> Vibration control in rotating machines is linked to a critical speed, to an excitation at rotation harmonic or to rotor dynamic instability. <...> The dynamics of system is characterized by natural models. <...> System has a tendency to vibrate at their natural frequencies. <...> The main interesting problems in the dynamical study of rotor systems are the critical speeds. <...> We can design the predictive controller that can use the measured disturbances. <...> By introducing predictive control it will be made possible to greatly reduce the vibration. <...> DYNAMIC OF ROTOR SYSTEM In real machine, very high vibration levels can be reached. <...> Usually largest rotors are operated below the critical speed, but mostly the high-speed rotors are run fast over the critical zone. <...> Even if the real rotors are very different from the simple case of the Jeffcott-rotor, also in this case it is possible to consider eccentricity, by introducing a distribution of eccentricity along the rotor and generalizing the results obtained by means of the simple model. <...> This rotor system has only two degrees of freedom or, if we use a rotating co-ordinate system, one: the radial displacement of the disk. <...> The displacement in Cartesian coordinate system is: yx = Re(r), yy = Im(r), 83 №1(44)2014 (январь-март) Технологические машины where r - is the complex radial displacement of the disk in the XY plane. <...> The equation of motion at a constant speed of rotation is given by: mr cr kr m r e uu 2 it , where m - is the mass of the disk; c - is the damping coefficient; k - is the spring constant and r with overhead signs are the first and second time derivatives of radial position; mu - is equal to unbalancing mass; ru - is the distance of the unbalance from the geometrical <...>
