Решение задач поиска рациональных параметров трансмиссий шахтных дизелевозов методами прямой оптимизации

Abstract

The main (maximum efficiency) and auxiliary tasks (approximation of experimental data)of optimizing the parameters of hydromechanical transmission of mine locomotives using the modified simplex method of Nelder-Mead are considered. The possibility of finding local extremums on the basis of the preliminary probing space; evenly busting the initial simplex (using LP-τ grids) and localization of extremums found with the introduction of additional restrictions on the N-dimensional space of arbitrary objective function. Further refinement of the algorithm is supposed to be carried out in the direction of balance account for simplex vertices, to reduce the number of iterations carried out – considering the second best and the worst peaks. Also stopping criterion for calculating, on the principle of full coverage zones OOTSF localization, ie receiving a total of its examination developed.
