Popis: When developing models of critical mechanical engineering products, it is necessary to solve dynamic problems, taking into account changes in the dimension chains of links in the process of functioning of mechanisms. A method of calculating dynamic dimension chains as applied to solving direct and inverse problems is proposed. The solution of a direct problem is given under the condition that the stray field of the master link includes the errors of production and those related to the changes in the dimensions of the initial links under the action of operational loads. To obtain the value of the product part wear rate we propose using empirical dependences of the relation between the wear rate and formation of hydrogen in the process of interaction of materials.
