Abstract
Some complex modeling of typical external loads of structural systems elements has been conducted. The stress-and-strain state of fertilizers distributor metalwork based on the above-mentioned modeling has been simulated. A universal recording algorithm of both adaptive functions of bending torque moments and potential energy of deformations taking into consideration the unknown quantities of external supporting reactions and internal force factors has been found.Some analytical research has been done with the substantiation of possible cases of external load distribution around the perimeter of the machine frame under study. A bearing metalwork of an updated solid fertilizer distributor has been used as a case of study. The comparison of obtained results with found experimentally qualitative and quantitative characteristics of stress-and-strain state of the distributor supporting frame has proved the efficiency of applied proposed approaches and models in calculations of bearing frame metalwork’s with arbitrary specified distribution of external loading which makes the use of given mathematical model possible for similar schemes of machines supporting frames.
