The article presents the results of a mathematical model development and analysis of brake disk and brakeblockthermal state during braking with consideration for influence of the design, materials science and operational factors, for which the loading-velocitudionous parameters of interaction of the disk brake members, the mutual overlap coefficient, the friction unit geometric pattern, physicomechanical and physicochemical characteristics of the properties of friction materials, as well as the parameters of microdeformations realizable in the contact area and in the contactless areas of the brake disk surface have been taken. It has been shown that the temperature fields of the brake disk working surface differ in the absolute, maximum values by 5–10% (for the entire braking time) and up to 10 … 15% upon reaching a fixed time mark during braking with and without due regard for effect of the reversible deformations on the disk brake thermal state. It has been established that prediction of the generated and dissipated heat flux values during braking with consideration for influence of the reversible deformations makes it possible to improve the calculation adequacy up to 10–12%. The developed mathematical model adequacy has been assessed based on a comparison of the theoretical and empirical results obtained on a full-scale bench test set, the discrepancy of which does not exceed 20–25%.
