Dynamic Model of Technological Equipment Drive with S DOFs

The study centers on dynamic transients resulting from jump-like changes in controller of machinery electrical drive. Discussion requires description of dynamic processes in various operation modes-acceleration, deceleration, reversing, and transition between different angular velocities given DC and AC engines momentums conditioned on angular velocity values. Conditions in which technological drives operate necessitate relevant transient modes aiming either to provide for maximization of operation speeds, or minimization of losses, or limitation of dynamic loads generated in components of kinematic chains which link electric drive and working element, etc. Control of transient processes in the electric drive guarantees maximum operation speeds and equipment performance given specific limitations. On the basis of the dynamic drive model with two degrees of freedom, the different stages of the run-up mode were analyzed. The characteristics of the static component of torque on the shaft in steady mode and the dynamic component caused by the transient process are determined. The ways of reduction of the dynamic component significant for the drive operation are offered.

Own fluctuations in the drives of technological equipment based on a three-mass model of fluctuating torsional chain system are analyzed. Differential equations of motion of a mechanical system with three degrees of freedom are obtained. An analysis of the forms of fluctuating processes in the system is conducted. Conditions of orthogonality of own torsional fluctuation forms are considered, dependencies of own frequencies on system rigidity coefficients are determined.
