Автори: Николов, Н. Д. Заглавие: Влияние на някои технологични фактори върху остатъчните напрежения в лята греда за заден мост на товарен автомобил Ключови думи: residual stress, steel casting, computer simulation, finite Абстракт: This article has examined the influence that the following technological factors have on the distribution of residual stresses in casting: the addition / removal of ribs, the addition / removal of coolers, self-casting mold / establishment of the cluster of two casts. It compares the values of residual stresses (von Misses) in specific areas. It is shown that in the case with heavy vehicle rear axle cast beam distribution of stress at different options are similar, but the values of stresses in considered areas ranged within ± 20%.

Title: Effect of some technological factors on the residual stresses in heavy vehicle rear axle cast beam Keywords: residual stress, steel casting, computer simulation, finite element method Abstract: This article has examined the influence that the following technological factors have on the distribution of residual stresses in casting: the addition / removal of ribs, the addition / removal of coolers, self-casting mold / establishment of the cluster of two casts. It compares the values of residual stresses (von Misses) in specific areas.
