DEVELOPMENT OF MATHEMATICAL MODELS ACCORDING TO EXPERIMENTAL RESEARCHES
The analysis of mathematical models on the discrete points, received is carried out as a result of the experimental researches used for research and the description of processes, proceeding in piston engines. These models on theoretical and empirical are conditionally divided. On a concrete example it is shown, that use of models of planning of experiment as empirical can lead to to the big errors as these models are intended only for reduction of quantity of experiments, instead of for calculations. Check of the given experiments on this model leads to to the big errors. It is shown, that by the form by a curve it is appreciated (approximately, for example, as a polynom of the second degree) the equation describing results of experimental researches. Then factors in the found equation are calculated. The settlement data on offered model will well be coordinated to experimental data.
