THE METHOD FOR THE OPTIMIZATION OF THE FORM OF ASYMMETRICAL MULTISECTIONAL DETAILS
The agricultural machinery often has details with technological elements in the form of sharp transition from one section to another. At action of axial loading in the weakened sections of these details there is largest local tension which can exceed extreme values and lead to the loss of operability of products. At the design stage of new details by criteria of an optimality it is necessary to develop the analytical methods of the decision allowing to solve the return regional problems of mechanics of a deformable solid body. The purpose of the researches consists in the development of an analytical method of the calculation of an optimum form of multi-sectional details providing the decrease in concentration of tension for increase of reliability of agricultural machinery. In work, the procedure of the calculation of an optimum form of a transitional surface of a detail is being presented; results of the experimental researches are being given; it is also proved that as a result of the optimization of a form of an asymmetrical multi-sectional detail concentration of tension in it (detail) has decreased by 30%.
