| Abstract: | In this paper, a theoretical analysis of fatique life forecasting of the components of shaft shapes acted by random load and optimization of structure parameters was carried out. A method of computer simulation and fatique life forecast of mechanical elements was advanced. Moreover, the author proposed "damage degree" as a criterion in obtaining the optimum structure parameters. A relationship between the optimum design of mechanical elements and random fatique life was established. |
