Abstract

The object of the research is the process of design calculation of linear dimensional chains. The purpose of this article is development of a method to choose the most rational combination of admissions and deviations on the basis of modeling of accidental combinations of these parameters by means of a genetic algorithm and selection. Imitating modeling of calculations with the choice of the best option by the criterion used in the article provides the solution of a design problem of calculation of dimensional chains with high probability at rather broad range of a combination of the sizes and technical requirements to them. This criterion evaluates an error of a deviation of a design value of the closing link from a preset value. It gives the chance to the designer, even at the worst combination of parameters of the sizes, to solve a problem with the maximum error and to evaluate the directions of change of a design for the purpose of its reduction.
