| Summary: | Заглавие с экрана Представлено имитационное моделирование геометрических параметров наплавленного валика и результаты экспериментальных исследований режимов электродугового послойного выращивания. Имитационная модель построена в программном комплексе CONSOL Multiphysics. Результаты экспериментальных исследований обработаны при помощи программного обеспечения Компас-3D. Определен оптимальный диапазон режимов электродугового послойного выращивания. The purpose of the work consists in the development of a simulation model of pad geometrical parameters and in definition of optimum modes for the method developed for the electric-arc direct layer growth of metal parts. The formation of a simulation model was carried out with the aid of CONSOL Multiphysics program complex. The result processing of experimental investigations was carried out by means of Compass-3D software support. For the definition of geometrical parameters of the pad grown there were welded samples with a consumable electrode in the environment of protective gases. Further there were microsections made of each sample in the transverse direction. The microsections cut out were ground, polished with the use of ASM 10/7 NVL diamond paste. For the definition of the microstructure the microsections were etched in 4% alcoholic solution of nitric acid. The results obtained of the pad geometrical parameters are well correlated with experimental data. The error makes some 1…3%. On the basis of the model offered there is defined an optimum range for modes of electric-arc layer growth ensuring the required pad geometrical parameters. A pad height makes 3mm, a pad width - 3.5mm. Режим доступа: по договору с организацией-держателем ресурса |
