Effect of Dissipative Factors on Dynamical Processes in Controlled Technological Machine Aggregates
要約
Mathematical model for investigation of dynamical processes in controlled technological machine aggregates with considering dissipative factors of different physical nature was stated. It was shown that considering of only one type of dissipation and neglecting other ones can result in qualitative and quantitative errors in estimation of character of dynamical processes. Investigations showed that dissipation in contact zone of rolls and raw parts affects damping of oscillations of the main frequency. At the same time dissipation in electric motor promotes damping of oscillations on high frequencies. So, if we take into account one of the mentioned types of dissipations, then for certain relations of elastic-inertial parameters the modes of stationary oscillations are possible. For providing the given degree of stability of controlled technological group machine aggregate we suggested insertion of special dissipative means in one of elastic elements. We studied conditions, when it is necessary to insert auxiliary dissipative means and obtained formula for determination of characteristic of dissipative means.
