Design calculation of dimensional chains on the basis of simulation modeling

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.
