Lyashenko S. The mathematical models of rotors the systems of the diagnosis of the revolving machines

The thesis is dedicated to the question of developing the mathematical models of rotors for their application in the systems of the diagnosis of agricultural machines. There has built the mathematical model of the oscillatory systems "combine-rotor-man". The mathematical model of the rotor is offered, which allows for the flexure and irregularity of its rotation. There have been offered handy regressive models of the balance of rotor mechanisms, on the basis of which the forecasting models have been developed. For the estimation of the parameters of such models there has been offered an algorithm, which makes for the receiving of unbiased estimators. There have been developed the mathematical models of rotors, which allow for a not stationary state of their characteristics. There have been developed a method, technical means and a laboratory plan, which provide allround research of the oscillatory parameters of rotor mechanisms
