A.N. Polyakov USING OF PROBABILISTIC APPROACH TO THE CONSTRUCTION OF THE TEMPERATURE FIELD IN METALCUTTING MACHINE-TOOLS Utilizing the probabilistic approach in thermal modelling has been directed on achievement of adequacy the mathematical model to real processes in metal-cutting machine tools. All random perturbations on temperature process are divided in two independent groups. The first group of perturbation is connected with thermal loading, second group is stipulated by fluctuations of heat exchange. This division allowed to present building the probabilistic thermal model into two corresponding stage. This article represents the first stage. Here are described theoretical propositions for probabilistic thermal model by example spindle assembly on antifriction bearings. Three parameters of friction moment in bearing is chose as random magnitudes. Results of calculation experiments are demonstrated.
