Підвищення надійності та відновлення металоконструкцій транспортних та сільськогосподарських машин

Abstract

The frame constructions of transport and technological machines perceive the static load and dynamic load as a result of that in the process of exploitation cracks and other damages on certain areas are appeared. By the problem of establishment of elements of strengthening in dangerous areas, and also proceeding in descriptions of durability of such areas with the engendered cracks, there is a danger of damage of parent metal frames due to negative processes, which can take place during welding. In-process with the use of the programs of certainly-element analysis the possibilities of reduction of temperature overfalls are investigated, that cause local tensions that exceed border of durability of material and cause the danger of appearance of microcracks.
