Polyakov А.N. ACCOUNTING FLUCTUATIONS OF HEAT EXHANGE CONDITIONS IN PROBABILISTIC THERMOELASTIC MODEL METALL-CUTTING MACHINE-TOOL Private case of probabilistic thermoelastic model for metall-cutting machine-tool is proposed. Heat transfer coefficients are considered as system of accidental magnitudes. Theory of linearizing for accidental magnitudes functions is used in representation of model. Here was demonstrated that main criterion of efficiency in practical realization to linearizing procedure is linked with accuracy calculation corresponding derivative. Therefore some scheme for computation derivatives are represented. At the same time the efficiency of the solving of the system of linear equations provides the quality probabilistic thermoelastic model. Taking into account the large number of degrees-of-freedom the determined system, new compact matrix storage has been proposed. Also an analysis various numerical methods of solving systems of linear equations is implemented.
