Feasibility anlysis of novel technological principles of producing multicomponent mechanisms
Abstract
Structural analysis of technological processes by the graph method and based on the concept of technological state is applied to a feasibility study of principles of producing multicomponent mechanisms for accurate performance under operating conditions. A state is defined as a condition in which the quality indicators, specifically the geometrical precision, retain their levels attained in preceding stages or transitions in the process. Each technological operation is described by a directional graph, with both sequential and parallel transformations of technological states from one to another included. Dimensional errors are calculated with the aid of a corresponding transformation matrix, whereupon an error compensation chart is drawn which biases the manufacturing variance of geometrical parameters so as to compensate errors caused by influencing factors in service and their deviation from normal delivery acceptance level. These influencing factors are grouped into five categories: (1) ambient temperature; (2) force actions; (3) diffusion; (4) destructive actions; (5) radiation effects.
