Виртуальные испытания двойной несущей системы Пизанской башни
Довнар, С. С.; Лапука, А. Д.; Шведова, Д. Н.; Маненок, А. В. (БНТУ, 2022)FEA simulation of the double load-bearing system (LBS) for Pisa Tower is provided. Cylindrical trunk (T-LBS) is surrounded by 6-stage column system (C-LBS) in the telescopic manner. T-LBS is found out as the main object to bear the tower’s weight. Trunk is rigid and low-stressed. CLBS is partially (about 44 % of mass) hanging on the trunk by pliable cornices. Slender C-LBS is ...2023-01-26 -
МКЭ-испытания L-башни для создания несущей системы аддитивно-субтрактивного станка
Довнар, С. С.; Яцкевич, О. К.; Лапука, А. Д.; Шведова, Д. Н.; Аглушевич, И. Ю. (БНТУ, 2023)Transferring of the medieval L-plan tower in to the machine tool Lcolumn is discussed. Geometrical sample for hybrid (additive-subtractive) machine (ASM) is described. FEA is provided for L-column poured from UHPFRC. High stiffness of spindle units (up to 210 N/μm) is stated. Inner angle of the L-column is recommended for support placement. Ice filling increases Lcolumn’s rigidity ...2024-01-23
