FIELD: transport.

SUBSTANCE: invention relates to the automotive field and the field of machine-building for determining the thermodynamic characteristics of a block-modular cooling system for traction vehicles. Method consists in determining the parameters of the thermodynamic characteristics of radiators of the block-modular cooling system, used to calculate the values of heat functions over the entire operating range of the engine, and providing the possibility of determining and building a general characteristic of the temperature dynamic analysis of operation of the cooling system of the automotive vehicle during operation at various load modes of the engine. The type and characteristics of time variations of temperature dynamic properties, the position of movement and condition of the traction vehicles, the heat-loaded elements, assemblies, and parts thereof while heated and cooled are determined herein for each studied functional parameter during operation of the engine and during unsteady-state modes thereof. The statistical characteristics of time variations of temperature dynamic characteristics of heating and cooling are determined for each studied functional parameter with repeated calculations during operation and idle time of the engine. The values, and/or positions, and/or movements, and/or states of the controlled functional parameter are calculated based on the resulting characteristics in accordance with the time of operation or idle time, for the current range of positions, movements, and states of the heat-loaded elements, assemblies, and parts of the technical apparatus, and at the moment that said values, and/or positions, and/or movements, and/or states calculated with a set probability reach the permissible values determined therefor, a graphical image of the temperature field of the block-modular engine cooling system is built.

EFFECT: increase in the accuracy of determining the heat transfer of components of the cooling system of traction vehicles.
